Launching the Z ?

One thing to note on the automatic transmission of our Z's is that if you push the brake torque too much the computer will shut it down back to idle. You have to stay below 2k rpm level when doing this to get the converter to stay locked.

Under 2000, you're just creating excessive wheelspin. The launch is hard after you spun for a couple seconds. But there's a slight cut in power before the pop.

I keep VDC in first to control wheelspin on launch. Then release vdc in second so power doesn't cut while upshifting so aggressively. Vcd will cut power the second a bump throws off the balance of the Z. I can control that on the wheel without cutting power. Hence VDC off.

Beginner's question, how do you turn VDC on and off? Or am i miss-interpreting any terms here?

Lower dash left side of wheel. You can't miss it. Round button marked VDC and the unlit word "Off" under it till you hit VDC off..
