Strange problem with idle control

Post by Beemerturbo »

Hi,
Every time i start my engine the megasquirt controls the iac stepper motor so the engine idles around 800rpm, thats perfect but when i go for a drive on the highway and rpm is around 5000 for a while the stepper motor comes out and doesnt go back in so the engine idles around 2000-3000 rpm. If i start the engine again it's back to normal.
I'm using MS extra 3.2.1, idle control is on "iac stepper moving only"
(sorry for my bad english)

the problem is solved. The pin from the stepper motor came out during driving. We set it to "always on" and now it doesnt come out
