I'm setting up my SBC with an LS1 throttle body and trying to get the LS1 IAC to work, but when i run the MSII on the stimulator and adjust the coolant temp the IAC moves sparatically and doesn't seem to move repeatably.
Can someone their LS1 IAC settings?

Re: ls1 IAC motor settings
Note that there is a 4 sec delay between moves - this is by design to keep the motor from constantly moving in response to clt temp electrical noise. This may appear to be jerky movement, but it isn't. There is also a hysteresis input, so it may not move until a certain no. of steps have built up.
