Do you use SRM at all or all the time?

I have a feeling that SRM throttle position overrides actual throttle position during a set of time prior to gear engagement.

I believe this behavior is what is causing this lag we all have been complaining about. If we could remove neutral position awareness and allow actual throttle position to override if it's greater than SRM throttle position value, I believe we'd be considerably better off with this issue.

I'd like to see if there is a garage out there that can validate if this action is occurring so that we can provide Nissan with data they can action, if the choose to.

When I don't utilize SRM, I don't receive this lag issue at all.

Good thinking... I use it all the time - also VDC off

IcedZ did the "special" tech ever get back to you in March?

Just bought a Z. I don't mind kinks here and there, as long as they are fixable, but if not I have little patience for this sort of thing. Mine hasn't really dogged yet, but I have noticed a jerky acceleration from a stop. Bummer is nothing this side $75k excites me in vehicles besides the Z (not for performance, Mustang GT can match that, more that excited "I want to drive this thing fast" sort of feel).

I have never once used SRM and I still get the lag. SRM on or off apparently doesn't affect the lag issue.

No, the guy's a little bit of a flake I think. I called him again in April, but no answer. I've been really busy, I just switched jobs. Need to call him again after I get my car back (assuming the new cat doesn't fix it =\ )

Yeah, first can be a little... unrefined.

Got my car back, took the long way home for an extended test. At first, it felt awesome. But, toward the end of the trip, oil sub 220, the same problems hit.
Busy this weekend, going to test drive a mustang next week. Easy way to fix it =)

IcedZ · 05-06-2011, 01:05 AM
