#5294, "RE: Finally got MSII to control stock IAC stepper"
In response to In response to 18




          

Ive been toying with the settings for my IAC and I have an almost perfect idle (again). This is a lot easier than it was last year. I also just today changed my close delay from 3 seconds to 0 (meaning do not close) and the car responds to part throttle SO much better. When its still cold it has to open farther to idle where I want it to, about 60 steps, so when I tap the throttle it jumps a little high. After its warmed up it will sit about 35-40 and a very light throttle tap (2-3%) raises the throttle by a few hundred RPMs, and when I let off my dashpot adder stabilizes it and PID takes over. When I had the IAC closing when the throttle was depressed, a throttle tap would send the RPMs high and slowly settle to a normal 3% as the IAC closed. And also, taking off in 1st gear you could feel the car surge and see it go lean from the IAC being open until it closed to where my VE table was set at.

After setting IAC to do not close and a quick retune, my car now idles, takes off, and cruises better than it EVER did with the stock 95 ECU. I would recommend others at least try the do not close option if the car doesnt like very low RPM or taking off in 1st.
