HSayaovong what I meant was where in those tables? Flat advancing/leaning out the whole table is not ideal.
Have you any idea what AFR you're eventually aiming for? The problem is that if your LTFT start taking fuel out you will run leaner than desired and that's not good.nif you want to do this, look on Romraider for basics on the ECU. There's some really helpful info here too as well as NASIOC. Don't just look for OFT based info, any Subaru tuning references will do. Just just walk into this blind, do your homework.
