When driving an automatic I brake torque to 1500 -1700rpm, then floor it. I usually take a sip of coffee too.

I do this in all my rentals

Pretty sure they're not intended to actually launch. I'd bet that doing it over and over is just going to destroy your transmission. If it was intended to be launched, they would have added a Launch Control mode like the GT-Rs have.

If I'm remembering correctly, the old GT-Rs had transmission failures because of the stress that launching (foot on brake and gas at same time) places on the transmission.

Ultimately your call if you want to lunch your transmission, but just something to keep in mind

Definitely agree with ya, I don't do this that often cuz I still baby my Z, but i just wanna have the ability to make her work when i want to

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..

My way sounds dumb to people but it friggin works. Just try it first. But read what I wrote carefully so there's no cornball mistranslations "a la EDUB".

Hey Unknown_370 that is an interesting way of doing it im just curious, you mean to drop it into drive when you stop reving? does it matter that the revs are up or you wait until they go down?

DONT REV AND DROP. the only purpose of revving is for the algorithm logic sensory program to get a sense you will be driving aggressively.

Oh. One thing... When you initially hit the gas, you instantaneously press to 25%, then when take off is in sequence, floor it n change gears accordingly.

JARblue · 11-14-2014, 03:43 PM

Yes... the idea is that giving it a bunch of idles revs makes it think that you wanna go fast (which you do). So when the revs drop and you put it in gear and goose it, it performs better than if the engine were just idling prior to goosing it.
