"Rev hang" on my new 370Z

It's just the dbw programming.

Good call. Not SRM at all, but rather the "rev-hang" they program in for various purposes like emissions reduction

Do they spike up to wear they should be for the new gear, or above it?

If it is just to the level appropriate for the gear, that is supposed to happen.

I don't think it is really intentional, it is just an effect of the way they run their control systems.

yea i guess it spikes to where the rpm's should be for a new gear.... I still think the reving will prematurely wear the engine...no?

Not appreciably, and it will save your trans.

A fraction of a second of unloaded revving isn't really a problem for the engine, but that jump to the next gear can be hell on a transmission.

Either way, the transmission coding or some other type of programming, my brand new Z is not messed up so that makes me happy.
