MAF curve queston
Helllo everyone, not sure if i should post this here or in another section but ive always had a problem with my CEL coming on with my CAI installed. bank one and bank two lean codes. ive searched around and nothing seemed to have fixed it. i have a programmer and it has the mass air curve funtion on it. as suggested by others, i increased the curve in small incriments to see if i could reporgram the ECM to take more air flow but failed everytime. well instead of rambling on and on my queston is, what would decreasing the curve do? does it mean im trying to tell the ECM that less air is coming in or what? I love the sound the CAI makes with WOT and want to keep it on.
