I am running megasquirt pnp2 on a 88 mustang stroker with x cam. I am new to all this so maybe someone can point out some obvious changes that need to be done. I think the car starts up and idles somewhat normal cold but at some point it likes to find 1400/1500 and just stay there when its warm. The short data log I attached is a start up after its already warmed up.

You have closed loop idle enabled I see, this should be setup after you have a decent idle in open loop. You also need to figure out the range in which the valve works. I have some videos stickied in the digital tuning forum I suggest you watch them first

I did change it to closed loop because of a tuners advise on youtube, I'll change that back to open loop and check out your videos on the iac. thanks
