I never ended up doing this on my 135 and the gearbox feels completely different in the 1M.
I actually didn't think they'd have it on the 1M.
The gearbox on the 1M does feel different than the 135i, but that is not where the CDV delete will be of benefit.
CDV delete regulates the pressure for release of the clutch plate against the flywheel, to stop that jerky feeling between gear changes.
Absolute must mod... actually my first mod on both my 135i and 1M.
