I THINK I NEED HELP
I've followed the mastertune tuning guide to set the iac table to get a smoother idle, the basic map was to much rough on idle
But I didn't succeed; I can not get a smooth ramp to idle. It quickly start, no puff of black smoke, smell a bit gas but not a lot.
I have monitor the iac on cold start and adjust the iac step at each engine temperatures breakpoint on table iac warm up table, after I have tried to set the crank run step table value without succeed,
It always has a high flare on start, I have set all the crank run values to 0 and no change, I just succeed to get a   rougher idle than the basic map
Is there someone who could give me a hand with this?
Thanks

Did you clean the IAC ? The bore is at the 12 :oo position in the throat. Carb/brake cleaner while turning the ignition on and of to ove the IAC. you likely see lots of crud.

What map are you using? You are on the right track for flare up however a small bit of overshoot then the idle leveling off in a second or two is what I strive for. The rough idle is usually a timing or AFR issue, don't forget the VE table controls the AFR...if the VE's are off everything is off.
Try retarding/advancing the Closed Throttle Timing table a few degrees for a smoother idle.
Good Luck

I'm using UH205-002C2 map
if I'm using the close throttle spark table for idle,with DBW is the tps goes at 1% ? according to the tuning guide will be only active when under 1%.
Will this table work at idle when the engine temperature is over the highest table value?
can this table be used to help with deceleration popping if richen afr 20% column doesn't cure

thanks
