How to increase the power of a Grant 8 valve engine

And so in the first part I told you what can be done with the motor of your 8-valve valve for 10-20 thousand rubles. In the second part I will tell you what can be done with an 8-valve valve so that owners of 16-hole valves start to get nervous. For more serious tuning of 8 holes, you already need a different budget, many know that the first horsepower is the cheapest, and to get the same amount you need to invest a lot of money. Many at this time are starting to collect 16 cl engines, but if you are a maniac and pointing at a photo of a charged 16-hole with a knife, hanging on the wall, because a guy beat you, and sometimes girls come across, with vegetables on the prior, then the situation is something like this... Again, we won’t bother too much with the 8-hole bottom, bottom from Granta is a completely worthy alternative to the heavy stock bottom end. 1. We put grantoniz, 7000 rubles 2. we choose a more serious camshaft, for example STI-4 (12.1 / 308-300), OKB engine 68.72, Stolnikov 11.8-322, Nuzhdin 12.1-292 is also an option, 4000-8000 rubles 3. You still have the receiver from the previous config, 4. The cylinder head must be modified, with a shaft whose phase is in the region of 300 and higher and the lift is over 11.5 mm, it is necessary to modify the cylinder head, 7000-8000 rubles 5. For the fuel system: injectors we change to more productive ones, 107 Volgov will do, 2500 rubles 6. In addition to everything, you need to tighten the degree with a cylinder head gasket from the grant, 7. Setting up the ECU - 4000-4500 rubles Total: + 25000-30000 rubles to what you already had installed, not cheap, but for this money you can simply turn your 8v into 16v, and then the output is already 130-135 forces and this motor spins at 8000

this is already enough to punish a certain Priora with vegetable shafts and not only... But there is one more catch - this is a gearbox. The stock gear ratios will not be able to realize the full potential of such an engine, so you will have to get into the gearbox, change a pair, row, etc. pops up at 20,000-25,000 rubles...So it’s up to you to decide

The LADA Granta car (Lada Granta) is a front-wheel drive budget model of the Volzhsky Automobile Plant. Various modifications of LADA Granta are equipped with several types of gasoline engines with a volume of 1.6 liters and a power of 87-106 hp. With.

At the same time, the 21116 Lada Grant engine is very popular among car enthusiasts, since it is installed on affordable versions. Next we will look at the Grant 87 hp engine, its pros and cons.

21116-features and tuning of the Lada Granta engine

Technical features

The basis for the creation of this unit was the engine 21126 and 21114. The engine took pistons and a cylinder block from the Priorovsky one, the rest is not much different from the “dinosaur” 21083. Here the volume is 1.6 liters, nominally 87 horsepower, and the torque is around 140 N *m.
There is an electronic throttle here, as we had to comply with modern environmental standards. This means that the engine is programmatically and technically “strangled”, and its real potential is slightly higher than the rated power. The German company “Federal Mogul” took on the task of lightening the connecting rod and piston. The main advantage of lightweighting is reduced friction losses, which means lower fuel consumption and better dynamics. Following the advantages and disadvantages: the vulnerability of the pistons to detonation, a shorter service life due to reduced weight, the inability of the connecting rod to withstand even a slight hydraulic shock, the lack of counterbores for the valves, and this is inevitable for the pistons and valves when the timing belt breaks. I was pleased with the actual fuel consumption with such an engine: in the city it is 8.5 liters, and outside the city 6.5 liters.

What problems do owners of cars with engine 21116 face?

• Noises and knocks often occur at 150,000 km, as a result of an increase in the gap between the crankshaft journal and connecting rods
• floating idle speed due to faulty sensors of the electronic gas pedal “E-gas”
• The coil often fails, despite the fact that it is made by Bosch
• the engine often “snotty”, but this is a common problem with all 8-valve engines of the front-wheel drive Lada family
• a sudden break in the timing belt, which means the pistons meet the valves.

How to extend engine life. Proven Methods

• change the oil not every 15,000 km, as the automaker indicates, but once every 8,000-10,000 km
• adjust the valves once a year and replace the valve cover gasket
• change the air filter every 5,000 km, fuel filter every 10,000 km, spark plugs every 25,000 km
• The timing belt is changed every 40,000 km
• antifreeze must be replaced every 3 years or 70,000 km.

How to improve engine efficiency and tuning methods

Transition to a mechanical throttle and flashing

What I often hear is that owners complain about late throttle response. More precisely, too much time passes between pressing the pedal and opening the throttle. This directly affects acceleration and fuel consumption. For this, there are ready-made conversion kits from “E-gas” to a mechanical throttle. The average price of one is 1000 rubles, and the kit consists of a gasket, an adapter and a bracket for the accelerator cable.

After installing a mechanical throttle, you need to “teach” the control unit that there is no electronic throttle. You can also shift the cutoff to maximum speed, as well as install a larger diameter throttle, but I recommend no more than 52 mm. It wouldn’t hurt to install a “4-2-1” or “4-1” exhaust manifold instead of a catalyst - the throughput of the exhaust system will improve.

Installing a special kit to increase power

This configuration gives a significant increase in power, but the ECU will have to be flashed, since the engine begins to operate in other modes.

Replacement of piston, work on cylinder head, intake and exhaust

What is needed for a major overhaul, part-time tuning

• forged piston group with valve counterbores. It is slightly larger than standard pistons, but just as light and resistant to detonation, and the pistons are not afraid of “meeting” with the valves
• forged reinforced connecting rods for a wide liner
• wider phase camshaft and split aluminum gear
• intake manifold with wider passages and larger throttle body
• insert instead of catalyst
• injectors ZMZ 406
• Luzar Turbo water pump
• bronze valve guides, bronze seats and lightweight valves
• boring the cylinder head channels and grinding the head plane
• setting the fuel pressure regulator to 380 kPa.

All of the above parts, before installation, were calculated to obtain a balanced engine, with the most even torque shelf. As a result, I had to roll back the firmware on-line and configure the ECU in all modes.

What we got as a result: maximum power of 140 horsepower at 6900 rpm, torque increased to 195 N*m. Acceleration to 100 km/h was 8.2 seconds. Fuel consumption increased by 1 liter, taking into account refueling with only 95 gasoline. Once a year, the engine undergoes a major cleaning of the oil, cooling and fuel systems, as well as cleaning of the throttle.

The estimated resource of such a motor is about 250,000 km. How it will be in practice is unknown, since according to data on the Internet, the maximum power without loss of resource is 120 hp.

How to make a car more powerful.

Automakers usually, when designing a new model, try to reduce not only the vehicle’s fuel consumption, but also modernize the power unit to increase its power. But, unfortunately, many owners are often not satisfied with the factory power of the car. But not everyone knows that in fact, everyone can add horsepower to their car at their own discretion. There are several ways you can add power and make your car faster.

Method No. 1

Increasing engine power

– There is a common misconception that if you install the entire exhaust pipe with much smaller diameter pipes than the factory, the exhaust gas velocity will be reduced, which will lead to back pressure of the exhaust gases, which will flow back into the engine. This is why many people believe that excess pressure in the exhaust system will lead to a decrease in torque.

But that's not true. Ideally, any sports car uses exhaust pipes of different diameters. Some parts of the system have a small pipe size. Some, on the contrary, have a large diameter. This is done in order to provide an optimal level of exhaust gas velocity for each engine speed range.

– In order to change a section of the exhaust pipe, it is necessary to accurately measure the length of the pipe that goes after the catalyst. Of course, it would be better if you contact a specialized company that specializes in tuning exhaust systems to replace the pipe.

– Open the hood and locate the air filter housing. Remove the old filter. Clean the inside of the housing where the filter was installed with a damp cloth.

– Keep in mind that installing a zero resistance air filter will actually allow particulate matter in the air to enter the engine and oil filter. In addition, when using such a filter, the flow of oxygen into the fuel system increases, which of course will affect fuel consumption. Due to an increase in the flow of oxygen into the system, in any case, the service life of the mass air flow sensor will decrease, which can often fail after installing a new filter.

This is a difficult and expensive tuning. But one of the most effective for increasing power. There are several types and types of turbochargers:

– There are turbines (the most common) that direct large flows of air into the intake manifold, which provides a rapid increase in horsepower when you press the gas pedal. This type of turbine is very common on older cars.

“In addition, there are more modern turbines that draw in additional air flows using special blades. Air flows enter the sealed compressor housing. Next, the air flows pass through the constricting cone. As a result, the pressure of oxygen entering the engine increases.

– There are also centrifugal turbochargers, which use active impellers with blades. Centrifugal forces can rotate the impeller at speeds of up to 100,000 rpm. As a result of the rotation of the impeller due to centrifugal forces, a vacuum area is formed in the center, as a result of which air is thrown towards the edge, which ensures the absorption of oxygen. This type of turbocharger is the most efficient available today.

Method No. 2

Chip tuning

It is not uncommon that with the help of chip tuning it is also possible to reduce fuel consumption.

If your car is not equipped with a turbocharger, then as a result of chip tuning the increase in power will not be significant. On the contrary, if your car has a turbine, using new firmware for the engine control program you can achieve a significant increase in horsepower.

– On the Internet and in many car services, chip tuning services are often advertised for little money. As a rule, such chip tuning at most includes connecting a computer to the “brains” of the car and changing several settings of the working mixture in the combustion chamber. But this dubious tuning is unlikely to add even a few horsepower to you. As a rule, for a noticeable increase in power it is necessary to completely install a new microcircuit with modified software, which a priori cannot be cheap. So be careful and don't fall for advertising.

– To install a new electronic engine control unit, carefully read your vehicle's repair manual. You should know the procedure for replacing the car computer. Before disconnecting the unit from the connector, you must first remove the negative cable from the battery. Only after you have removed the terminal, disconnect the computer from the cable harness.

– Connect the new vehicle control unit. Attention. Depending on the make and model of the car, the installation of a tuning sports car control module can be done in a different way. After installing your new computer, connect the negative terminal back to the battery.

Yes, at low speeds, chip tuning and other types of work will not lead to an increase in fuel consumption. But with a sharp increase in speed, fuel consumption can increase by 40-60 percent.

In addition, remember that installing a turbocharger also increases the cost of owning the car. The thing is that a car with a turbocharger needs more careful scheduled maintenance.

How to increase engine power Lada Granta 8 valves

Togliatti-made cars continue to be popular among numerous car enthusiasts. First of all, because of the affordable cost. However, even the most ardent fans of AvtoVAZ admit: the Lada Granta has many shortcomings. So those who want to get a faster and more comfortable ride, an aesthetic appearance of their car, soon after purchasing it begin to improve their purchase. Fortunately, tuning the Lada Granta Sport is not too complicated, it has been worked out and can largely be done with your own hands. And everything necessary for modernization is sold in specialized stores.

We do powerful tuning of the Lada Granta ourselves

When choosing a car for thorough tuning, many people turn their attention to cars from a Russian manufacturer. This is due, first of all, to the fact that AvtoVAZ cars are low in cost. When tuning such cars, you can achieve significant improvements in both the vehicle's performance and its appearance. After all, car tuning can be compared to other creative works, and the master needs a “clean canvas” to create a new masterpiece. Tuning the Lada Granta can be either thorough: installing all new units and completely changing the appearance, or partial: improving the installed engine, suspension and other components.

If you do a thorough tuning of the Lada Granta, then immediately determine that this is a do-it-yourself Lada Granta tuning, in some cases, it will be almost impossible - the changes are so strong.

What's the result?

As you can see, with the modernized 8-valve engine of the Lada Granta, not only fuel consumption has been reduced, but also dynamic performance has increased, since there is a reduction in mechanical losses. Also a plus was the reduction of vibrations and noise, and increased comfort.

Despite the fact that in recent years the production of domestic cars has reached a new level, which resulted in the release of the Lada Granta model, Avto-VAZ is still unable to demonstrate the quality and reliability of foreign-made cars. Therefore, the best solution for many owners of these cars today is chip tuning of the Lada Granta.

Malfunctions: causes, elimination

Like all internal combustion engines with mechanical adjustment of valve clearances, the 11186 engine requires periodic adjustment of this characteristic. In addition, during operation, characteristic “diseases” of this particular version of the power drive were identified:

When repairing piston and crankshaft engines, it is recommended to use original components from the AvtoVAZ manufacturer. Because only he uses special technologies for strengthening structural materials. From third-party companies, the metal may be “raw”; the resource of such consumables cannot be analyzed.

Updating the factory firmware of the AMT Lada Granta robot box

Updating the factory firmware for the robot box or AMT (automated manual transmission) to the latest version UAA6CB060040. With the new software, shift times from 1st to 2nd gear and from 2nd to 3rd gear are reduced by 30%. Crawl mode is activated. This feature allows the vehicle to start moving forward without pressing the gas pedal. This option is needed to increase the comfort of the robot when driving in a traffic jam. To support confident starting in slippery conditions, the “winter mode” function has been added, which allows you to start moving from 2nd gear. Reprogramming the AMT takes approximately 20 minutes.

Power measurements after chipping

They can be made on special stands. We measure there without any problems, the only negative is that it’s a little expensive. Therefore, savvy car owners solved the problem within budgetary limits. It turns out that there is a special program for the phone that produces fairly accurate numbers. And if you do not strive for the filigree execution of a task, then it will certainly do. Similar programs for iPhones have already become famous. What should you do if you have an Android? And there are free options here. But, according to experts, their measurements are sometimes greatly distorted. There are paid ones, but they are inexpensive. It’s better to buy one of these, put it on your phone, enter the required data for your car and try to measure the changes in power after chipping the engine.

Firmware for VAZ 2114

Publication date Jun 15, 2014, Categories VAZ cars |

Firmware for VAZ 2114, this issue haunts many motorists. It is believed that by cleaning the “brains” of a car, you can make it faster, more dynamic, and easier to drive.

Of course, in order to professionally reflash the standard ECU, it is recommended to contact special tuning studios, but if you are well versed in the essence of the issue and know exactly what you are going to do, you can replace the VAZ firmware on your own.

Before you start work, you need to find the necessary program that will fully match your car, and then the standard firmware of the VAZ 2114 can be replaced.

To search and select a program, you can refer to the extensive information contained on the Internet. Before reflashing the injector, make sure that this procedure is really necessary.

If any of the car systems does not work adequately, this means that operational errors are not due to a malfunction of the injector or the ECU in general.

Before replacing the firmware, be sure to make sure that the standard software of your car does not provide for disabling misfire detection.

If this option is “registered” in the standard program of the VAZ 2114 car, the need for flashing “no longer exists” automatically. Before replacing, it is necessary to accurately determine the type of standard firmware.

This is done with the help of competent diagnostics and scanmatics, the use of which will accurately reflect the system configuration of your vehicle.

Next, the firmware is replaced according to the general rules. Purchase a DF with a cover and a special pin for the camshaft. Connect the adapter and constantly focus on its readings (in real time) during operation.

Communication with the ECU should be restored, but if an error is reported when connecting to the port, you will still not be able to flash the VAZ 2114 firmware yourself. After this, download a new program (at your discretion) and modify the ECU.

For greater convenience, experts recommend that when performing this work, you generally remove the controller from the car. Upon completion of work, check the functioning of all systems: power supply, ignition, main relay, programming permission.

Lada Granta 8 valve: main faults

Even taking into account the fact that the internal combustion engine of the Lada Granta 21116 is not the most complex unit structurally, certain problems associated with certain engine malfunctions may still arise during operation.

Main malfunctions and methods for their elimination:

• The occurrence of knocks and noises. The problem is misaligned valve clearances or defects in the pistons, connecting rods or crankshaft main bearings. The problem is eliminated by adjusting the gaps by repairing or replacing damaged parts;
• The occurrence of floating idle speed. The problem is related to a failure in the electronic throttle control system “E-gas”, namely the failure of its sensors. The malfunction is determined by testing the system and replacing the sensors;

Reviews from car owners about the 87 hp engine.

Most reviews are positive.

Mostly problems occur due to low-quality fuel and lubricants. The engine may start to stall and run intermittently (floating idle, stalls, loss of power, etc.). In this case, the “Check Engine” malfunction icon (indicator) should light up on the instrument panel.

The engine pulls well at low end; on the highway, even with a full load, there is enough power. This is especially noticeable when compared with a Ford Focus automatic: engine capacity 1.6, power 100 horsepower. Granta drives more fun, Focus “deflates” after 80 km per hour. As for Focus - personal experience, I owned just such a car.

Maintenance

In accordance with the manufacturer's regulations, engine 11186 must be serviced in the following order:

This is exactly the frequency of maintenance that the ICE 11186 device is designed for.

Engine VAZ-11186 1.6 87hp. This is a Kalashnikov assault rifle.

Why can you blame AvtoVAZ? Yes, for a lot of reasons, the plant greatly damaged its reputation in the 90s and 2000s, when it was torn and shaken by everyone who could. In fact, 20 years were lost in development, and competitors jumped far ahead. But in the mid-2000s, the plant rose from its knees and began producing Kalina with a VAZ-11183 engine. The VAZ-11186 engine is a deep modernization of the VAZ-11183 engine. Someone may write in the comments that they say they stuck a new lightweight piston and that’s it. And when the timing belt breaks, the valves also bend, so they only made things worse. Apparently our mentality is such that we don’t want to accept everything new. I remember how everyone criticized injection cars, saying that the carburetor was more reliable, but all this electronics only made it worse. Another memory: Priora came out in 2007, and everyone criticized it as best they could, called it ugly, said that the “ten” was more beautiful. And now the new Lada Granta model is coming out, and it has an 8-valve engine on which the valves bend! Grant, according to our tradition, got it to the fullest. What has changed:

Of course, it remains cast iron, the cooling system for the cylinder jackets has been optimized. Piston oil cooling nozzles appeared.

received enlarged coolant flow channels, increased inlet channels of the working mixture. The cylinder head itself received aluminum hardening at the manufacturing stage, as well as different seats and valve guides.

a new metal two-layer gasket has increased the reliability of the gas joint and tightness, with less tightening force. This made it possible to reduce the diameter of the bolts holding the head and cylinder block from M12 to M10.

New lightweight pistons from Federal Mogul and new connecting rods were used. We managed to reduce the weight by 39% for the piston-pin-connecting rod set. The pistons received an anti-friction coating on their skirts to prevent scuffing when starting the engine.

increased from 9.6 to 10.5, which requires the use of 95 gasoline, which is noted in the instruction manual.

A Gates timing kit with an automatic belt tensioner was used, which is larger in diameter, which required a longer timing belt.

We installed a more reliable bearing and oil seal and increased productivity.

Receiver (intake manifold):

got longer channels, which had a beneficial effect on the torque, it increased.

Electro-mechanical throttle:

Now the throttle is cable-free, and the control unit has the ability to control the air supply to the cylinders. And yes, now the decorative engine cover is inaccessible, does not tighten, and apparently it was expensive to develop a new one)

the exhaust into the catalyst has changed, the channels have become a little longer, and the exhaust gases have become less sticky with each other, resistance and losses have decreased.

I received a generator belt tensioner with its own roller, now it has become much easier to control the tension.

The engine cooling system has been redesigned, a new thermostat has appeared, all this has made interior heating more efficient, and engine overheating with a working system is practically eliminated.

The changes affected everything we could touch. The new engine turned out to be as reliable as a Kalashnikov assault rifle. It doesn’t matter what you fill it with, 92, 95, gas, it works properly. It is so reliable that modern engines on foreign cars can envy the service life and cost of maintenance. It doesn't burn oil. It starts at low temperatures. It has the potential for chip tuning, after which it starts to drive like a gear. Soon this engine will be valued, just as the Renault K7M and K4M engines are valued. Definitely worth recommending for purchase to those looking for a reliable workhorse with low maintenance costs.

And here are the owners’ reviews about chip tuning

1. Of course, the factory firmware of the sports Grant has some bugs. If, for example, we drive in second, if we roll, we press on the gas, it does not gain momentum at all. Sometimes there are dips and jerks when switching. So I decided to get it chipped by a specialist. Immediately upon leaving the service station I noticed that it drove really well and came to life. The cutoff was set to 7200 - excellent sound. We added speed to the engine. In general, it was an interesting car. On some foreign cars, with additional chipping, you won’t even understand whether you did it or didn’t do it, there’s practically no difference. And here – everything is palpable, I’m happy! Now I’ll install the correct exhaust so it can breathe. Victor Levandovsky
2. The difference is immediately noticeable after replacing the factory engine software. If previously the speed switching occurred at 4500 rpm, then after adjustment the switching occurs already at around 5000-5500 rpm. The response to the gas pedal has become faster. The power has increased, which allowed the Lada Granta with automatic transmission to slip. I was pleased with the work done (from the site https://xn--80aal0a.xn--80asehdb/car-description/reviews-tests/lada-granta-reviews-tests/421-chip-tyuning-dvigatelya-lada-granta-otzyvy .html).
3. Video review: Talked to friends. Found a man. I asked for it. ADACT firmware for Sports. The car has become more interesting. Acceleration is observed throughout the entire range of engine operation. The cutoff is moved far away. But there is no point in turning it further than 6500, since the intake-exhaust phases are peculiar. I went to Krasnodar the same day. I filled it with 98 Lukoil. Traction appeared throughout the entire range. The gap disappeared when you unscrew the first one, then switch to the second one, my car “shut up” and became stupid. And now the operation of the internal combustion engine has become more elastic, the torque is more stable (from the site https://adact2.ru/chip-tuning/otzyvy/lada/granta).
4. And now about what interests most readers of this article. What has changed after tuning with the chip? The dullness of the gas pedal has disappeared, pickup from 3000 has become much better (and switching to a lower gear generally gives the effect of going to boost :D), the cutoff has shifted to around 7000 rpm (good for the future shaft, but that’s next summer), the failure when switching from 1 has disappeared by 2. Unfortunately, I did not notice any changes in consumption. As it was 10, it remains so (from the site https://adact2.ru/chip-tuning/otzyvy/lada/granta).

But in general, reviews about chip tuning of the Lada Grant are different. Some users do not share the opinions of the authors of the above videos and texts at all, preferring not to change the factory firmware of the engine. But do not forget that there are many firmwares that allow you to approach chipping each car individually. And what the result of replacing the software will be will also directly depend on the technician.

Result

After chip tuning is carried out, you will notice the following improvements:

• the car will sharply pick up speed and stop stalling after pressing the gas pedal;
• acceleration will be smooth and without jerking;
• if you need to overtake, you can quickly accelerate to maximum speed;
• the car will consume less fuel;
• power will increase;
• traction and dynamics will improve.

The most important advantage of such an upgrade is that no mechanical changes occur in the engine. With the correct settings on the on-board computer, the effectiveness of the result is guaranteed.

And instead of a heart - a fiery engine

• Car owners have long figured out all the disadvantages of the engines that Ladas are equipped with. They are inherent in almost all copies of the line.
• The engine often stalls when starting. Alternatively, it gains momentum too slowly. In urban conditions, taking into account traffic jams and traffic lights, driving the Lada Granta becomes difficult.
• The Granta does not move very well on rough roads and unpaved roads at low speeds. The car handles wet country roads especially poorly.
• There are also problems with high revs: driving through mud in this mode is simply dangerous.
• High climbs are, to put it mildly, not ideally overcome. You have to slow down before the hill, switch to 4th, or even 3rd gear.

What modes are optimized when chip tuning a Granta power plant?

The plant periodically makes some warranty adjustments at service stations, but not everyone uses this service, and those who undergo warranty maintenance do not always receive it. As a result, owners continue to operate obviously faulty cars, not suspecting that it is enough to correct the electronic algorithm. The point of changing the ECM software is to optimize the operation of the engine and transmission.

Lada Granta modes that require improvement:

• ignition timing;
• injection time value;
• exhaust emission control systems;
• algorithm for determining the octane number of fuel;
• automatic transmission operation.

If desired, the second oxygen sensor can be removed from the circuit to further remove the catalyst.

What to expect from ECU tuning

Reflashing allows you to correct errors and optimize the performance of the car.
Companies offering chip tuning services develop and offer various software that allows you to optimize the basic performance of cars.

This process allows you to correct all sorts of errors, create a backup copy of the initial settings, study and adjust characteristics, as well as make changes and test new firmware of electronic components.

If you need to return to default settings, this is done almost instantly. But those who have already reflashed Granta will never return to the standard factory settings. After flashing you can get:

• reduction in fuel consumption by 5%;
• high speed characteristics;
• 10% increase in power;
• smooth operation of the automatic transmission;
• improved traction.

And that's not all. In this case, not a single intervention is made in the mechanics. This is one of the cheapest ways to make Granta better. There is one caveat. If the car is currently under warranty, after flashing the ECU, the warranty is invalid.

"Deep" tuning

True engine boost enthusiasts can go much further in their pursuits. Among the most popular measures:

• installation of forged pistons;
• cylinder boring;
• installation of a nitrogen accelerator;
• turbocharged engine.

If you intend to strengthen the engine of your Granta Sport in this way, it is better to carry out tuning in a comprehensive manner. Installing a forged group is pointless without intensifying the fuel supply, and turbocharging accelerates the wear of serial pistons. And do not forget that increased “sporty” engine power requires intervention in other car systems. It will be necessary to strengthen the brakes, modify the suspension, and make changes to the transmission. Without these procedures, you will not be able to enjoy the speed of your fret for long.

Upgrading the exhaust system

To further strengthen the engine of the sports car, it is recommended to supplement the tuning by making changes to the exhaust system. Namely, dismantle the existing exhaust manifold and install a “spider”. It will collect exhaust gases from several cylinders at once into one conducting pipe.

When purchasing such a collector, experts advise contacting manufacturers who have proven themselves well. Their products use high quality steel, which is treated to prevent rusting, and the wiring diagrams are calculated as successfully as possible.

Tuning Lada Granta: bringing the car closer to ideal

Togliatti-made cars continue to be popular among numerous car enthusiasts. First of all, because of the affordable cost. However, even the most ardent fans of AvtoVAZ admit: the Lada Granta has many shortcomings. So those who want to get a faster and more comfortable ride, an aesthetic appearance of their car, soon after purchasing it begin to improve their purchase. Fortunately, tuning the Lada Granta Sport is not too complicated, it has been worked out and can largely be done with your own hands. And everything necessary for modernization is sold in specialized stores.

What cars was it used in?

Created in 2011, the 11186 engine is used as a power drive for several models of the auto manufacturer AvtoVAZ:

• Lada Kalina II – station wagon, sedan;
• Lada Granta (Lux and Norma equipment) – liftback, sedan;
• Lada Priora – sedan, station wagon, hatchback;
• Lada Largus – minivan, station wagon, van;
• Lada Vesta - station wagon;
• Lada XRay is a compact crossover/high hatchback.

Lada XRay
Improved engine characteristics allow it to be used on any front-wheel drive car in the event of a swap rather than engine tuning.

Increasing sports power

If you take care of your Lada Granta Sport, engine tuning should affect the filters. Factory - it is recommended to replace it with a zero resistance filter. It comes complete with special impregnation. Dust particles settle on the lubricant, and purified air passes at higher speeds through many microscopic holes.

The zero resistance filter provides:

• 10% above the normal rate of passing oxygen;
• more complete fuel combustion;
• increase in engine power by 3-5%, depending on the initial engine size.

The disadvantages of a zero resistance filter include:

• the need for private service. The filter should be washed at least every 10 thousand kilometers. And if you drive on country roads, then twice as often;
• purchase of a special cleaning agent;
• more frequent filter replacement - “nulevik” can withstand no more than 20 cleanings and new impregnations.

If these nuances do not bother you, and you are interested in increasing the engine power, you can replace the filter yourself. The factory air filter is removed along with the housing, and a zero filter is installed in its place.

How does the electronic unit on Grant work?

Before making changes to the car's firmware or performing diagnostics, you need to consider the basic principles. As much as some would like to jump right into making practical changes, you need to understand how the electronic “brain” works.

Any computing system, be it an ECU or a home PC, is a storage device. A home PC contains photos, videos, games, and work software. The computer constantly stores the user’s actions, errors, and data about software failures. All this is hidden among system files hidden from view.

The Lada Granta electronic control unit is also a computer, only the tasks it is designed to solve are more specific. There is also diagnostic information here. It is stored in RAM. This memory stores all the data that comes from various sensors. Information is stored until the block calculates everything it needs for some actions, then the information is erased from memory.

When it comes to diagnostic information, the car owner must be very careful. RAM cannot operate without a power source.

The control unit is a mini computer with specialized functionality

However, in addition to the RAM, there are other memory blocks of the controller. They are completely independent of nutrition. The data stored in them is unchanged. Unchangeable until new firmware is updated. These are PROM and ERPZU.

The first chip stores all the firmware data that was made at the factory. All the original algorithms and operation schemes of all nodes are embedded here. All diagnostic information, calibration data, vehicle weight, engine power and other Grant parameters are also stored here.

The second chip stores anti-theft information. Here are the codes that are on the alarm keys. If the codes do not match, then Grant will not go.

Attention to the salon

The design inside the Granta is not bad, the seats are quite comfortable - there is lateral support and heating. However, if you want to own a non-standard version of the Sport Grant, tuning the interior is still necessary. At least in minimal quantities.

• In the case of the Lada Granta Sport, interior tuning most often begins with the installation of alternative dashboard lighting. The algorithm of actions is simple: the devices are dismantled, and the LEDs on the board are soldered to a variant of a different color.
• Next, you can finish the handles and mirrors to match the body. The most commonly used is spray paint.
• A good idea for the Lada Granta Sport: tuning the interior - in terms of the “chrome” frame of the deflectors, as well as the console.
• You can cover the elements inside the cabin with vinyl.
• We supplement the heating of the mirrors by integrating an electric drive into them.

Try to implement these ideas for tuning sport grants 2022 - the only thing that can limit the flight of its owner’s imagination is a lack of money or lack of time.
