I recently upgraded my clutch in my Z06 to a Monster Triple Disc, which engages in a different spot than the factory clutch (earlier as you begin to release the pedal). As a result, my rollback/hill assist is behaving really weird. Since it goes by clutch pedal position and the clutch catches earlier as I'm releasing, the rollback assist doesn't disengage right away. As a result, by the time it does, my car will lurch forward pretty violently. I'm wondering if the rollback idle can be completely disabled somehow or if the clutch pedal can somehow be relearned to work with the new clutch. I tried setting the Enable VSS to 0 mph because the description says that below that speed it will allow rollback idle to enable. In reality, it's not a "less than" threshold; it's a "less than or equal to" threshold. So, it still enables when i'm at a complete stop on enough of an incline.
My hacky fix for now is to release the brake pedal, keep the clutch pedal all the way down, and wait for the car to start rolling backward after a couple of seconds before I start coming off the clutch. But, it takes 2-3 seconds for that to happen, so people keep beeping at me in traffic because I don't go right away. This is really irritating, and I'd really appreciate any help if anyone has encountered this before!
