what is iacv adjust in uberdata?
my car doesnt idle smooth at all with uberdata but with my obd2b ecu it runs perfect and my iacv is blocked off cuz i broke the nipple off. what is the iacv adjust and what is it adjusting. would it help out my idle? i put my timing at 12 and fuel pressure at 33.i also read that you should advance the timing in the idle thing. but once the car is warmed up it idle pretty good and doesnt flucuate as much.

Re: what is iacv adjust in uberdata?
here is what i found on the pgmfi board
iacv adjust, aka iacv slider, is used to adjust your iacv (idle air control valve) which controls the amount of air let in to the tb at idle, commonly used to fix fluctuating/surging idle. sorry if that doesn't help much but i tried whats your setup? i used to have alot of idle problems with uber but most of that went away agter switching to CROME |

I never got the cold idle right using Uberdata. I just put a piece of rubber hose in the inlet side to make my own orifice. That took care of it.

since you said your iacv is blocked off, no adjustment would help at all anyway

Take off the fast Idle valvle, take the plate off and screw in the spring loaded mechanism. The should clean the cold start idle up.
