GMPP ls2 engine controller, case learn ? Having an issue getting the car to idle with new cam (ms3), when the car decides to idle it idles great and the afr sits between 13.8 ish to 15.0. Generally speaking however it just wont settle in to an idle without very slowly taking my foot off the throttle.
From what I've been reading it sounds more like a throttle body sensor learning issue, but maybe i'm just not reading the right things? I'm using a tbss 87 mm tb.
I have HP tuners and have had no luck with making adjustments to the minimal amount of idle parameters given on a dbw setup. Had no issue tuning the car on the dyno or making changes at the track.
I'm probably leaving out some vital info here but really just starting to get lost in the searching so decided maybe someone knows what i'm missing or just not getting.
