Another PWM Idle Control Issues Thread w/ MS2 v3.0
I've got my combo tightened up and road ready. I've been working on my idle and like most that are just starting out, I can't seem to get it nailed. I've done all the research and applied it without any luck.
Currently, in Closed Loop Idle, the car is idling between 650-700rpm with the idle valve UNPLUGGED. With the idle valve connected, it idles at 2500rpm. I've read several posts on here (keepitoldschool has several good threads) as well as MSefi and MSExtra, even used several suggested settings, but still can't get the idle to come down. I've set values to high and low extremes just to see which settings effected the idle and the lowest it got was 1800 but crept back to 2500. I'm not sure where to go from here and was hoping to get some help working this out.
