What should my air fuel ratio be WRX?
14.7 is the ideal mixture. The stock ECU keeps the mixture lower to prevent detonation.
What should AF correction 1 be at?
It should ideally be in the +/-5% range. Your AF Learn 1 looks good.
What is a f correction?
AF Correction 1 (AF Correction 1) -> Short-term (immediate) fueling correction in closed loop based on input from the front oxygen sensor. This is a percentage correction of the injector pulse width. Positive values indicate fuel is being added as a result of the correction.
What should the ratio of petrol to air be?
The ratio of this mixture affects your fuel economy, performance, reliability, or even if your car runs at all. The scientifically “perfect” mixture for normal petrol is 14.7:1, that is 14.7 times the mass of air to fuel, but that doesn’t mean a car should run at that – far from it.
What happens if I Change my air fuel ratio?
Other issues, oil, cooling, and general strength of components can always destroy an engine, but the number one killer, especially among tuned turbo engines, is detonation due to incorrect air/fuel ratios. SO WHAT THINGS WILL CHANGE MY AFR?
How is maximum power obtained with rich air fuel?
On the other hand, the maximum power is obtained with rich air-fuel mixtures. As explained before, putting more fuel in the cylinder at high engine load and speed, cools down the combustion chamber (through fuel evaporation and heat absorption) which allows the engine to produce maximum engine torque thus maximum power.
What’s the best fuel ratio for a car?
For optimum fuel economy 16-17:1 is usually best, leaner than that and the car will begin to misfire. Maximum power is usually found between 12-14:1, but this may be too lean for safety on many engines. For maximum reliability at full power, air/ fuel ratios from 10.5-12.5:1 are considered best, depending on the engine.
