DIY Stillen Supercharger

wortmeister

The VDC has its own separate CPU, and is unaffected by the Stillen/UpRev -supplied ECU supercharger flash.The VDC can be disengaged, or engaged, via the factory button switch--with or without a supercharger installed. My problem post supercharger installation is that the rear braking force limiting wheelspin on launch, controlled by the VDC computer, is inadequate to prevent frying the rear tires, even if the pedal is stabbed from a 20 mph rolling start. This may be due, in part, to the torque multiplication of the 16.53 final drive ratio with the auto trans' first gear. The higher 1st-gear final drive (14.01)with the 6 speed manual might lessen the problem.
