Do-it-yourself firmware for priors | Tricks of Life

Chip tuning of Lada Priora is a change in the software (chip, firmware) of the electronic engine control unit to increase power, reduce fuel consumption, eliminate failures, and ensure stable operation of the engine control system.
Lada Priora cars with control units M73, M74, Bosch 7.9.7 and Bosch 17.9.7 are available for flashing. For tuning we use software from leading Russian developers: Paulus chip, ADACT, Ledokol.

The proposed chip tuning software is intended for use on ordinary (non-sports) cars without the goal of obtaining maximum power and torque, without reducing the service life of the units.

You'll get a well-balanced increase in power and torque not only at high rpm under full load, but also in the low and mid-range, without increasing emissions.

After installing the modified software, improved driving characteristics can satisfy even the most demanding car owners.

The firmware is focused on comfort in driving: elimination of factory software errors, elasticity, reliable starting at any temperature, no dips and twitching, freezing of speed, elimination of sluggish acceleration dynamics, excessive fuel consumption. When the air conditioner is turned on, the loss of engine power is significantly reduced.

In addition, it is possible to eliminate errors due to non-functioning oxygen sensors (lambda probe), remove the software catalytic converter (catalyst), and also reflash the Lada Priora to Euro 2 or Euro 0.

The appearance of error codes P0130, P0131, P0132, P0133, P0134 and other errors associated with a faulty lambda probe, catalyst errors P0420, P0421, 0422, P0423, P0124, P0430 can be eliminated forever with the help of reprogramming and without compromising the driving characteristics of components and units. The warranty for the operation of the modified software extends to the entire service life of the vehicle, that is, indefinitely. Working time 1 hour. For each car, a certificate is issued with a unique authentication code, which can be verified on the software developer’s website.

In addition, for the Lada Priora it is possible to disable any errors, remove the adsorber, remove the immobilizer, adjust the temperature of the fan, disable misfires, disable the brake and clutch pedal sensors, adjust the idle speed, change the cut-off speed, disable the rough road sensors, the camshaft sensor.

What exactly are we talking about? Flashing is changing the operating characteristics of the Lada Priora engine by recoding electronic components. Thanks to the variety of firmware from productive and experienced programmers, modern upgrading of the Lada Priora car provides an opportunity for anyone who wants to improve the performance of their “iron horse”. Each Priora model, through a chip located in the control unit, provides a different effect: the ability to operate the engine comfortably on different gasolines, increasing power at low speeds and reducing fuel consumption, turning off the neutralizer control, optimizing the smooth operation of the air conditioner.

Pros and cons of Priora chip tuning

The Internet is replete with stories about the fantastic possibilities of chip tuning. It says that only by updating the controller firmware you can increase engine power by up to 50%, torque by up to 30% and reduce fuel consumption by 15%. However, this contradicts the laws of physics. The power of an internal combustion engine is the product of torque and speed. To increase the motor power, it is necessary to increase one of the indicated factors.

It is almost impossible to increase torque programmatically, but you can increase the number of revolutions per unit time by reducing the ignition timing. However, this increase in Priora engine power is limited and does not exceed 5-7%. The consequences of such an “improvement” must also be taken into account. Ignition advance causes an increase in temperature in the combustion chamber and an increase in the content of carbon dioxide and carbon monoxide in the exhaust. This harms the ecosystem and threatens problems with passing exhaust gas control.

After modification of the Priora engine, it becomes sensitive to the quality of the fuel, or rather, to the octane number of gasoline. An increase in engine power by 5% is practically not felt, and reprogramming threatens to cause additional problems and loss of the car’s warranty.

Malfunctions and repairs of the Priora 21126 engine

In 2015, production of the NFR sports engine began, called 21126-81, which used the 21126 base. And since 2022, cars with 1.8 liter engines 21179, which also used the 126th block, have been available.

The most basic malfunctions of the 126 engine

Let's move on to the malfunctions and shortcomings, what to do if the Priora engine is running rough, sometimes flushing the injectors solves the problem, it may be the spark plugs or the ignition coil, but the usual thing in this case is to measure the compression in order to eliminate the problem of valve burnout. But the cheapest option is to go to a service center for diagnostics. Another common problem is when the engine speed of the Priora 21126 fluctuates and the engine runs unevenly, a common disease of VAZ sixteen valves, your mass air flow sensor is dead! Not dead? Then clean the throttle valve, there is a possibility that the TPS (throttle position sensor) needs to be replaced, perhaps the IAC (idle air regulator) has arrived. What to do if the car does not warm up to operating temperature, there may be a problem with the thermostat or the frost is too severe, then you will have to put cardboard on the radiator grill

A little about firmware

If you still decide to upgrade the ECU yourself, use only high-quality firmware. According to reviews from car enthusiasts, Paulus firmware is a good option, as they “correctly” change the settings of the electronic unit. Moreover, they should be downloaded from official sites, and not from third parties. Because you can run into a fake and spoil the characteristics of the car.

Therefore, be extremely careful when choosing new software, since the cost of an error is very high and there is a risk of damaging your car with low-quality software.

Rules for handling the motor after flashing

Chip tuning, carried out by a highly qualified specialist, really improves the performance of a naturally aspirated engine: it increases its power, increases throttle response, which is especially important in overtaking mode, and reduces fuel consumption. When overtaking, the maneuver time is reduced, you have to press the gas pedal less when driving without acceleration, and change gear less often when using a manual transmission. Otherwise, driving a chip-tuned car is no different from driving a regular car.

Individual modification of the engine, performed professionally and using modern equipment, has a positive effect on the functioning of the engine. Chip tuning allows you to make the operation of the power unit more flexible and dynamic. At the same time, it is also necessary to take into account the negative consequences of such alterations: the service life of the catalyst is significantly reduced and the engine service life is reduced.

Modern methods of ECU firmware and equipment for this

After this, Bosch again took a step towards simplification. The new Bosch 7.9.7 block is already flashed by removing just one microresistance. Well, Russian developers have again created a good analogue (January 7.2), which in general can be stitched without “surgical intervention”. And then M73 for Priora. But it already contains the firmware. Same resistance as Bosch. However, it is just as easily removable.

What equipment is used to change the Priora firmware?

There are now many devices on sale that are designed to connect an ECU with a personal computer. These are adapters that transcode data from the “brains” of the Priora into an understandable PC interface. The most popular devices are the following.

• Adapter from Scanmatic.
• Block programmers from NPP NTS.
• Firmware downloaders from SMS.

All of them come with instructions for use and a set of cords with connectors for connecting to different computers.

Firmware

Only a programmer who has full knowledge of the structure of a car with an ECM can create firmware for the Priora ECU from scratch. Therefore, all auto electricians involved in chip tuning use ready-made modules. You can find them on specialized websites and download from there.

Firmware classification

The programs installed on the Priora computer are quite unified. That is, the middle option in the sets of tables for engine operation was selected. And buyers have different driving styles. They have their own ideas about fuel economy and other parameters. Conventionally, types of firmware can be divided into three categories.

The features of these programs can be determined by their name. Moreover, each of the categories also has dozens of different modifications, and are selected individually for each driver. By the way, it is possible to install two options simultaneously on one Priora, with a switch button.

The Economy category also includes firmware adapted for gas equipment, which has become popular recently.

Firmware of the first samples

What makes owners change, do chip tuning, “Priors”? Since the mid-2000s, the Euro-3 standard has been firmly established in production. This is a dual oxygen sensor system. The second one is located after the exhaust catalyst, or particulate filter. The thing is that due to the quality of the fuel, this sensor and the catalyst itself often fail. The control unit reacts to this by sharply reducing the fuel supply. Driving turns into sheer torture. And replacing them is expensive. Therefore, the main goal of Priora chip tuning is to install firmware with Euro-2 parameters.

What is an electronic control unit (ECU) chip?

Everyone knows that chip in translation means “slice”. It is no less widely known that electronic chips are information storage facilities for computer systems. Likewise in a car, a chip is a microcircuit that contains the “firmware”, “operating system” of the ECU.

How does this happen

This system is based on reading sensor readings. Schematically, the principle of operation of an engine with an ECM (Electronic Engine Control System) looks like this.

1. Signal receipt from various sensors.
2. Processing of received data in a microcircuit, chip, ECU.
3. Switching on of actuators according to the provided tables.

The operation of the sensors is based on various principles, but the essence is the same, a change in voltage during any action. Thus, the crankshaft position sensor changes the voltage at the moment when a gap appears in front of it in the toothed rim of the pulley. A change in voltage at this moment lets the computer know that the crankshaft is rotating and it’s time to supply a spark and fuel. The throttle position sensor (TPS) shows the degree of throttle opening by changing the resistance. In this case, the ECU, in accordance with the attached tables, regulates the opening time of the injectors. That is, it increases or decreases the fuel supply. All this is done by the same Chip.

The first cars with an ECM and replacing their firmware

At first, the USSR auto industry collaborated with the American one. This was in the 80s. The ECUs installed on the first versions of “injection” cars were of the corresponding brand - GM. Then a domestic analogue was created - “January 4”. In general, the order of release of ECUs with firmware for domestic cars was as follows.

• GM VAZ (January 4th analogue)
• Bosch 1.5.4 (January 5.1)
• Bosch 7.9.7 (January 7.2, M73 Euro3)
• Bosch 17.9.7 (M74) Euro-4, E-gas.

Main stages of chip tuning

Before you begin upgrading the engine, you must bring it into a condition that meets factory specifications. Otherwise, the cost of chip tuning and the setup itself will be pointless. The reprogramming procedure does not depend on the make of the car or the number of camshafts with 8-valve or 16-valve mechanisms. Chip tuning of the Priora engine consists of four stages:

1. Reading the standard program in the ECU - this procedure is carried out through the OBD diagnostic connector.
2. Editing a downloaded program.
3. Uploading the edited, firmware program back to the controller.
4. Checking the operation of all vehicle components on a special stand equipped with instrumentation and mechanical rollers, or in the field.

If the program needs to be modified, it is adjusted and uploaded back to the ECU. The described procedure is repeated until the desired result is achieved. You can do the firmware of the program yourself if you have knowledge in the field of computer programming and special equipment.

Video on how to prepare an SD card for flashing the radio

Firmware order:

1. Copy the firmware files (Chain.bin, chain.lst, NK.bin, TINYNK.bin) to the root of the SD card.
2. Remove the flash drive from the USB port.
3. Insert the SD card into the MMC.
4. Restart the radio (for Lada Kalina 2/Priora - hold down the power button for 15 seconds, for Lada Granta hold down the volume button for 15 seconds).
5. During the download, an update will occur, after which the radio will boot into desktop mode.
6. Without rebooting the radio, go to the screen calibration mode (Start/Settings/Control Panel/Stilus/ to the Calibration/Recalibrate tab), then press the screen during the countdown.
7. Reboot the MMS with the SD card inserted.
8. The firmware of the radio is complete, the SD card can be removed.

Transition to j7es firmware January 7.2 Lada Priora

1:502 The first valuable investment in a new car was the acquisition of normal brains, January 7.2 I can flash them myself, and they are suitable for online rollback.
I decided to use j7es firmware as a basis for experiments. This is a new project to develop a sports version of software for the January 7.2 ECU. The scope of application of this firmware is light and medium engine tuning. In total, the firmware contains 415 settings, adjustments and tables. ecusystems.ru/tags/j7es

— Possibility of calculating the air consumed by the internal combustion engine based on data from DBP and DTV sensors — Automatic launch program (launch control). By turning off the cylinders and reducing the ignition angle. — Online configuration on a regular (non-engineering) ECU, by capturing one of the calibrations into the online control of a special program, OpenOLT. — Possibility of cut-off up to 10200 rpm — Possibility of connecting additional ECU outputs: Cut-off indication lamp, Control of 3D rpm/throttle map, Additional fan (in this case, the fan can be turned on either by TZH or TV) — Additional functions of the “CE” lamp ": overheating indication, cut-off indication - Algorithms and calibrations related to environmental standards have been removed - Current algorithms have been optimized in order to achieve greater performance and increase the overall response speed of the entire internal combustion engine control system. (UZ according to the speed-throttle table, Mixture according to speed-throttle) - Firmware j7es is universal software and can be used in any modifications of the ECU January 7.2, namely: 8kl. and 16 grades, classic (without DD and DF), viburnum. 1:3300 I rolled out the calibrations directly for my engine, although I didn’t take out the Wideband Oxygen Sensor, I rolled them out in the usual way, a standard DC. The FunTune program helps well with this; it automatically rolls back the control unit and monitoring station according to the standard oxygen sensor.

Launch control has also been put out by eye for now, for normal hauling you need dry, warm asphalt. So far the acceleration table looks like this:

I made a video of how it works in dynamics. Cut-off of a car standing still, at 3000 rpm. Before the cutoff, the OZ is first filled up, and after 3000 the injectors are turned off. After the start of movement, the cutoff smoothly shifts upward, to 6300. By the way, at 6000 “CE” will light up.

About online capture of one of the tables. With the OpenOLT program, it is possible to capture one of 15 tables in online management. To write the adjusted table into the ECU memory, you will need to re-upload the firmware. This is, of course, not a full-fledged engineering unit, but it is much more convenient than pouring each calibration into your brain a dozen times in search of the optimal result.

The end result is very pleasing, I haven’t taken measurements on slippery roads yet, but according to the ass meter, it’s much more dynamic than standard brains.

Engine firmware, great review from the master

What does the firmware of the engine control unit (ECU) affect?
If I replace the factory firmware, what are the pros and cons? Which firmware is better? These and other questions were answered on the Lada.Online website by a specialist who has been involved in chip tuning of cars, including LADA models, for about 15 years. Stanislav Polyakov began to work on engine firmware since the days of the VAZ 2114, Prior and Kalin cars. For more than 10 years he has been working in a specialized center for repairing Mercedes-Benz commercial vehicles. Engaged in repairs and flashing of Mercedes-Benz trucks and Sprinter vans. Now he is actively involved in chip tuning of modern Lada Vesta, Lada XRAY and Lada Granta cars. Total experience working with firmware is more than 15 years.

Question

: What does engine firmware provide or, as they say, the “brains” of a car?

Answer

: Chip tuning allows you to reveal the potential of the engine more fully. In this case, ecology fades into the background, and in the first place are the power characteristics, which make it possible to achieve better torque, elasticity, power, etc. Also, firmware can solve the problem of long engine startup, change the temperature at which the fan turns on, solve problems with jerking when shifting gears, familiar to many Vestavods, problems with the immobilizer, etc.

Question

: Really, I can’t make normal firmware at the factory?

Answer

: At the factory, engineers make firmware that must meet toxicity standards. Therefore, the factory firmware suffocates the engine for the environment.

Question

: Where did the firmware names of MMK, Chelyaba, Icebreaker, Paulus, RSW, etc. come from?

Answer

: Tuning authors take factory firmware and make their own based on it, calling it according to their brand.

Question

: Does the engine power change after the firmware?

Answer

: Power after engine firmware is most often not measured, and even if it is measured, the test bench readings are not an indicator of the quality of the firmware. A car with firmware can drive much better than a factory one, the pedal will be more responsive, it will respond faster to the gas, it will accelerate faster, but the power may remain approximately the same or slightly more than the factory one (as for naturally aspirated engines).

There are firmwares that show amazing results on a dyno, but in fact the car doesn’t drive at all. The car just jerks and detonates, it is impossible to drive with such firmware. In my practice, many people bought such firmware and then gave up. I have it too, I tried to install it, the car doesn’t drive on it at all, it sometimes breaks out from under itself, or on the contrary, power loss begins. Therefore, measuring power after flashing the engine is not entirely correct; the stand measures power within one gear and with the pedal constantly pressed to the floor, but in life we ​​don’t drive like that.

Question

: Does firmware affect engine life?

Answer

: In general, no, but if it is unsuccessful and the car detonates on it, then of course this will greatly reduce the service life, or even kill the engine.

Question

: Will fuel consumption change after the firmware?

Answer

: Consumption depends on the author of the firmware and the driver’s driving style. For most, consumption decreases.

Question

: Which firmware is better to choose? What advice can you give?

Answer

: For those who do not have an aggressive driving style and who want to get rid of dips when switching, who want to get an adequate gas pedal, but will not drive like crazy, this is how I upload firmware from MMK. These are very balanced firmwares, the golden mean between smoothness and dynamics. It doesn’t happen that after flashing the car the car drives like crazy, and at the same time it would be smooth. That is, these are things that are incompatible with each other.

MMK Super Dynamic is available for 1.6 engines with manual transmission. It allows you to get maximum dynamics from the car. Firmwares are suitable for those who like to drive. These firmwares have amazing traction, the car drives very well, but the transition from engine braking to acceleration mode is very abrupt. If you upload this firmware to someone who doesn’t like to drive, there will often be complaints about a very harsh pedal, and the ride becomes uncomfortable.

Recently I have been uploading firmware from Chelyaba to 1.6 engines with AMT (“robot”). He made firmware for Vesta with creeping mode. At the factory, 1.6-liter engines are not equipped with creep mode firmware, because the engine does not know how to accelerate. This was done at the software level, and as I understand it, they don’t want to pay money for the development of completely new software for 1.6 engines, so they decided to leave these engines without creep mode. And in the Chelyab firmware the idle speed has been slightly added to make it easier to get underway. And when the clutch is released, the “robot” accelerates a little. The car with this firmware drives very cheerfully.

Chelyaba also has firmware for a robot without crawling mode. If we compare it with MMK, then Chelyaba will be an order of magnitude more dynamic, but sharper, and MMK will be smoother.

The situation is similar with 1.8 engines. Those who want smoothness, I flash MMK, those who need more drive and sharpness - Chelyaba.

By the way, Chelyaba is now working hard on firmware for the 1.8-liter engine. He bought a Vesta 1.8 AMT for himself, and over the last month he sent me about 10 versions of different firmware. The guys and I test them, and we pass the results on to him, he then edits them, etc.

There are advertised firmwares, which in fact are not at all as wonderful as the consumer is told about it; on some firmwares, cars detonate, on some, the car simply does not drive much better than the factory one. Again, many authors have their own segment of priority cars, and for other cars they make mediocre firmware just to be present on the market in a given make/model.

Question

: Who is the best person to contact for engine firmware?

Answer

: You need to beware of those craftsmen who claim that they write firmware for engines with their own hands. To write good firmware yourself, you need to know very well the theory of how the internal combustion engine works and know a lot of nuances, have extensive experience in this area, as well as a team of testers who would test this firmware. They usually steal other people's firmware and upload them under the guise of their own.

We had one “master” in the Moscow club who took free firmware from the Internet, uploaded it to people for money, and then they started having problems with their cars.

Therefore, my advice is this: if you are going to flash your car, do not fall for the “masters” who claim that they do the firmware themselves. Look for a specialist who will offer you firmware from trusted authors, and also try to find reviews from real clients of this specialist.

Question

: Can you recommend proven professionals?

Answer

: I recommend contacting:

If you still have any questions about flashing engines for LADA models, you can ask them in the comments, Stanislav will try to answer them.

What firmware to install on Priora 16 valves

Welcome to ChipTuner Forum.

Theme Options

Brother Priora has it. 2010 M7.9.7+ V174DT05. Full luxury. Ran 3000 km. Passed 1 MOT. There are no comments on the car. Now we want to upload some commercial firmware. Requirements: 1. To be as insensitive as possible to the inclusion of the air conditioner and be normally adapted to it (timely switching on of two fans, probably slightly increased idle speed, so that they do not float under load, well, etc.) 2. I would like to get maximum power from the engine from bottom to top, because brother is a racing enthusiast. 3. I understand that the consumption will be greatly increased during extreme driving, but what will it be like with a normal calm driving style? Much more than the factory one? 4. We are not going to remove the catalytic collector, I don’t think we will gain much from this in power, and in general we won’t interfere with the engine and gearbox. We don’t need any increased throttles either. As it was from the factory, let it remain so, so that when for maintenance drive, you could download the serial program and calmly undergo maintenance.

That's all the requirements. Does such firmware exist? I looked at commercial ones, one has an ideal XX, the other pulls perfectly at high speeds, the third is just a speaker for E2. Well, which one should I choose? I want XX good and traction. I looked at the M73 firmware for Priora, there is an ideal one for air conditioning, why doesn’t Bosch have one ideal for air conditioning? In short, I’m confused.

Dear Prior owners! No matter how leniently they are treated, the machine is not that bad. She would like a more decent noise, low-end torque. Cadney and ABS where available are also good. I've owned a hatch for 3 years. First of all, I was forced to take up anti-shumka. As rain rumbled on the roof and cobblestones on the bottom. Tough. Next, I drew attention to the peculiarity of all Priors. This is its outright stupidity at revolutions from 1000 to 3000, and this is at 98 hp. Rowing slowly uphill when there is interference kills you. You can start when overtaking only with at least 3000 on the tachometer. For a year I studied the topic of chip tuning, which I initially treated with prejudice, especially after a lot of comments about what inept chip tuning leads to. Burnt out valves, torn pistons and connecting rods. The abundance of commercial firmware offered on the Internet for ridiculous prices for all cars was frankly alarming. Communication with professionals convinced me that I should still try. There have been quite a few arguments in favor of chip tuning. The main thing is to understand what you want to have from this, this is the first, and second, buy firmware only from eminent, well-known chipmakers, and not impostors, fortunately, you can count the number of professionals in this market in Russia on one hand. I will name only three with whom I had to communicate. This is Paulus, Icebreaker, Adakt. Giving a car for chipping to unknown people, unknown calibration editors, and taking on any car, fulfilling any whim, to put it mildly, gives rise to an idea. I am being scammed, and shamelessly. And at least grass won’t grow there. Chip Tuning, like the Vostok, has a thin body. So, I still had to solder all the necessary adapters, drivers, cords, switches, programs for the computer for diagnostics and firmware, I uploaded the firmware directly from Icebreaker B11KSS(LR)01_v7.4, paying 1000 rubles. Communication here with ShMAX, who works on this topic, suggested the use of his ready-made pouring programs, but the lack of a specific proposal forced me to do everything myself. So, what is, naturally, the result. The result is pleasing, I’m unlikely to return to stock. That same low-end torque that was so lacking appeared. The reaction to the throttle is instantaneous, the impression is that the indicated 98 hp. were hidden somewhere. Fuel consumption has not changed. True, now it’s not Euro4, but Euro2. and is tailored for A95. I haven’t tried it with A92, the author didn’t recommend it. If someone finds the topic interesting, I ask for a response. Without interfering with the authorship, I’ll reflash the block indicated in the photo. There are no contradictions with the law. The contract for the purchase of this product assumes its use in my interests. The cost of this work is 1000 rubles. I let non-believers and doubters steer on the re-flashed one. I will only respond to live interest. There is no time for flooding.
