I'm trying to calibrate the MAF scaling on my 2017 Subaru WRX STI. I am brand new to tuning and can't seem to figure it out. Every time i try to make adjustements in the areas where i have above 5% fuel trims, there seems to be new areas in the MAF scaling where i get new fuel trims. Am I doing something wrong? Should I only be doing full throttle accelerations since im on the road?
What software are you using? Perhaps you could post some screen shots of the MAF scaling table that you are modifying.
Yea possibly. I am using Cobb accesstuner and I had been doing light accelerations to tune the maf scaling in closed loop. I'll see if I can post some screenshots later.
