The VAZ-2114 engine can have 8 valves or 16. The latter option is more powerful. In order for the car not to waste a lot of fuel and to work properly, it is necessary for the mass air flow sensor to produce the correct indicators. Its primary task is to measure the amount of air consumed and the reaction time. The accuracy of the indicators allows the controller to determine in what proportion the air and fuel need to be mixed. If the device shows inaccurate data, then the resulting fuel mixture does not correspond to the engine operating mode. In this case, fuel is consumed in large quantities and power is reduced.
Optimal air flow
If the mass air flow sensor is operational, then when the engine is running at 900 rpm, the volume of air used will be at least 10 kg per hour. When the speed increases to 2 thousand, this figure will increase to approximately 20 kg. If the volume of air at such speeds drops, the dynamics of the vehicle will also decrease, and accordingly, this will lead to a decrease in gasoline consumption.
If these indicators increase, this will also contribute to an increase in fuel volume. If the parameter deviates by 2-4 kg, you should not allow it, since in this case the operation of the power unit may be incorrect.
M73 - 2114. Increased fuel consumption.

What I'm treating: 1. valve adjustment - definitely 2. adjustment of DP leaks - definitely (although on the latest version 2.9 which I tried to fix this issue in software, it's terrible that they screwed up the IAC in particular and the IAC in general) 3. replacing the factory software - definitely.
According to the results: in winter in the city with an aggressive style 9.0-9.4 92 gasoline. With a moderate driving style - factory 8.6-9.2 per hundred.
And yes, 12-13 is the norm in stock for them.

In all cases, I threw in new 037 mass air flow sensors - the readings did not change

Oh, version 2.9 already? I was our last 2.6. Did you play with new cards? They made a lot of calibers in STR according to XX, my eyes wide open
