Do you worry about extremely high stft at WOT in 4th? I'm still learning but from what I've gathered the ecu is running closed loop mode and the AFR is what matters at WOT not stft??
The question arise's from some of my logs I have just seen which I'm not sure whether to be concerned about or not.
At 5435rpm I'm hitting 17.5psi, AFR 10.79, FP 1692.31psi and STFT +47.7!!!! LTFT is 0.
At 6163rpm 16.1psi, AFR 9.79, FP 1759, STFT +58.6 and 0 for ltft again.
Now that +58 means the ecu is adding a heap of fuel correct??
So if its adding tons of fuel it's because there is more air going in than the maf says it has seen go in correct??
Am I on the right path in thinking I STILL MUST have a small boost leak?
