Afm tuning help! Going to Dyno.

Ok guys im going to the dyno can anyone tell me exactly what i can adjust to get my a/f correct? I was told to turn this bolt. Is that what adjust the flap stiffness?

You have to turn the big black gear, Mark it's current position, and then hold it in place, pull back the silver arm that is stuck in one of the teeth and rotate it a few teeth, then put the arm back in place to hold the gear position.

For idle adjusments, pry off that blue cover in the bottom left and adjust the screw down in there.

ok does rotating it to clockwise make it run leaner and counter clockwise richer? Please explain which way i should turn.

[rs4pro3]

Increased tension(which ever way that is) should be leaner(makes it harder for the flap to open), where as decreased tension should make it richer(flap opens easier). Looking at the picture it apears clockwise is richer

Good man. Finally someone on R3V doing it right.

thats exactly what i thought. Ill post up the dyno sheets once i get them.
