MS1 v3 Tuning Questions BMW E30 M42

Post by Ryno »

I was hoping I could get a second set of eyes on my current tune for my car. Would anyone be willing to look it over quickly to see if there are any apparent issues with my settings? I am working on smoothing my idle and I have a pesky slight stumble (very small) almost like an idle hunt. I've adjusted ignition timing back and forth a few degrees and experimented with richer/leaner using VE table 1 when the car is fully warmed up. Still no progress. Smoked tested the full intake system for leaks/ non found. Idle is set with throttle stop as I do not have an ICV.

Any ideas?

Will post log asap

Engine is M42B18 4 Cyl Turbo

Please also post a data log of the problem; this will tell how the tune is working on the actual car.
