How to: Test Clutch Condition with the GT1

2022 M3 · 28-03-2022, 04:04 AM

Hi Nz_M3, I saw your post on how to check clutch and flywheel values in GT1. I've gone through those steps and my clutch and flywheel passed with very similar stats to yours. I have no issues shifting gears at all but do have an issue where my car often shudders/stutters like it's slipping when pulling away from a stop in 1sr gear. It's especially bad when other passengers are in the car or when going up hill.

I've ran the clutch slip point teach in in GT1 a bunch of times both hot, cold, and very hot with no success. I've also "teached in clutch valve values" which also didn't fix it.

Have you ever experienced these symptoms? Any other tips? I guess I'm going to keep adding my adaptation steps (like gearbox adaptation, longitudinal teach in, and maybe reset clutch curve characteristics) but am just nervous running extra tests and adaptations because I've read it can fail. Any other tips?

Really appreciate the advice!
