Killing VDC doesn't do a DAMN thing for those of us with the serious problem. It sounds like you guys just don't like the throttle mapping. This thread has to do with a serious problem where occasionally the car falls flat on its face with the pedal to the floor then gives you whiplash.

I haven't been here in a while, but I added the 34 row cooler from Z1, oil temps now run no hotter than 200, even on 110+ days and the car still does this. Absolutely mind boggling how Nissan can let this go. Its a serious safety issue...several times I have punched it to enter traffic etc and the car has fallen on its face.

I'm sorry, but there's no way that's from a little extra heat in the engine. More than one issue is being confused in this thread, repeatedly. What you're describing sounds like VDC to me, which is a whole separate issue. Even if our engine was at half its potential power due to some monumentally bad tuning at higher temperatures (and it's not...), it would still have enough power to get up and go in traffic.

With a bunch more Z experience under my foot, I agree it appears to be the VDC

You are 100% WRONG on this. I disable the VDC EVERY time I drive the car. Now that we are experiencing 50-60 degree temps here in PHX the issue has disappeared. When its 85 degrees+ the car bogs 100% of the time. Its a temperature issue, not related to the oil temps, since those are now running no hotter than 200 degrees ever.

This is a NISSAN design flaw in their engine management software...or a sensor issue. NOTHING else it could be.

Yeah, I got into a minor 'accident' because of it. I stalled on a steel hill, tapped the car behind me. No damage or injury. I traded it in the week after that.
