Stillen GEN3 vs. K fuel Multiplier

After that, you must log and tune AFR. If you are not able, you can request an e-tune map.


How you can "diagnose" the issue that I posted a week ago:
If you have uprev before you have mounted your GEN3, you can compare an old log with a new one.

You can observe that the max MAF was decreased! But the new air intake ingests more air!

Decreasing MAF, also decrease the BFS, that controls the scale in every maps in the ECU!!

So at High RPM no problem: Timing, VVEL and camshaft phasing are defined.
At low RPM the critic zone is about 2000 and 3000 RPM where all angles moves.
If the scale is wrong, the progressive increase in power is not linear as stock!!

If you observe, Stillen provide graphics that starts at 2900 RPM!!

Obviousilly more air = more gas = more power = less MPG!
Many users says that MPG was decreased after GEN3: BAD!

This means that the car runs lean!!

K fuel multipler adjust the new environment of the MAF mounting.
