GMPP ls2 engine controller, case learn ?
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.
