DIYPNP idle problem
We just got the DIYPNP up and running on our CSP car. Everything seems to me ok but it never idles down after it warms up. We are using the 3.x.x. msextra code and the base tune from diyautotune. I would like to make sure we have the wiring to the IAC correct, where in tunerstudio can I turn the IAC off and on to make sure it's wired correctly.
Thanks, Darryl

Not sure what car you have etc, but in the Megatune, in one of the drop down menus there's a idle option, check to make sure your idle speed is down to 950 (or whatever your target is).
I'd also check to make sure the MS is reading your coolant temp correctly. 160 I think is where it switches over to warm idle.

Zaphod was correct on the idle map being incorrect. That fixed the problem temporarily. After I fixed the map the car would idle down to ~900 after it got up to temp it was a touch rich but not bad and I thought we had it fixed. But we had been running the car with no alternator because we were still waiting on part to put the board together. As soon as the alternator was enabled the care pulsates during warmup (900 to ~1300rpms) up and down and started running very lean. back to the drawing board... Thanks for the help guys.
