DIY Stillen Supercharger

Nismoracer

OP is it true you no longer can run the car with VDC on with the SC install? If so do you have to turn it off every time you get in the car or will it stay off once you turn it off?

The kit runs fine with VDC on or off.

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.

I have less problems in 1st with my 5AT (08 G37s) with VDC on. The VDC is continually kicking on and off if I get on it hard though. I don't know what the difference in ratios is between the 7AT and 5AT. However, if I powerbrake to anywhere above 2200 RPM on launch with the VDC off it will spin all he way through 1st if I keep the pedal down. I am still playing around trying to find the best launch method. I am alson on stock sized NITTO Invos which don't hook up very well.
