So, I've been battling an on going issue with my car the past few weeks. One of my newest problems is that while logging with EvoScan at idle, the only fuel trim that adjusts is the Mid Fuel Trim. It acts just like it should, adjusting every 4 minutes or so, and I've been able to bring the trim close to zero. I have yet to take the car out for a cruise, to see what happens with the trims. Mods are in my sig.

Does anyone have any idea why the Low Fuel Trim would sit at .1008 but Mid Fuel Trim would adjust at idle? Please tell me someone has had this problem or have at least heard of it.

Thanks,

Nate

some of the versions of Evoscan had the trims defined incorrectly. this might be your problem . Look at the addresses and see if they are in correct order .

Just a thought

Thre formula is also wrong. Read the thread linked above.
