Torque Management... that's what I think I'm feeling. It was discussed before, but it's very annoying. Must get rid of this TM so I can induce whiplash. So far it's probably the throttle table mods wstar defined. :)

Has anyone tried the Apexi throttle controller?

This is getting stranger and stranger. My 08 G Coupe has no delay, up or down, aside from mass of moving parts which I can live with. The crunchy new Z I tested was lagging uprev in third (say) at 3500 and badly lagging downrev all across the spectrum. A tragic flaw. It's up to Nissan to straighten this out.

Lagging downrev???

As stated earlier, the easy fix is: don't go below 3K, or really more like 3500. If you're racing just keep the car in the right gear and there's no need to be that low. If you're just making a pass on the highway or something, surely you can see it coming and downshift earlier. This whole issue is really about drag racers (and even then you can avoid this at the strip with proper launch and shifts, so it's really just about street drag racers from a roll or whatever).

I totally agree with Mikey this is Nissans problem to fix!! Start a poll an see just how many people are having this issue. This is a serious flaw.

This issue goes beyond drag racers. I almost got tboned because the engine decided to bog when turning across a few lanes of traffic.

Most of the time it isn't that bad, but it is a serious problem.

Almost happened to me a year ago. I pulled out to make a left as this car was approaching. It's just a big blind spot with cars parked on the side. I floored it in the middle of a turn and the car just slowly hovered at low revs in 1st.

ive not encountered this..? :confused:

"when turning" - sure that wasn't VDC? But either way... If you think you're gonna need power, don't be down at 1,200 RPM to start.

Haha... nah, just getting the car to scoot as usual in 1st. It just doesn't budge down there. But you're right, if I get the revs up a bit higher in 1st the car gets moving. It's pretty much linear from there. I did that one time (even while the A/C was running) and spun the tires throughout the turn with barely half throttle.

Try disabling the VCD control...

As an update since I switched to the Southbend SS with 14lb flywheel, the issue is still there but far less noticeable. I have a feeling it has to do with torque management + our clunky trans design with the lightened flywheel the car jumps off the line cuts throttle very quickly then ramps up like hell if you push it quickly around 1- 1.5k rpm, it didn't fix the problem but it shortened the "return time" in a big way when the car ramps its power back up.

Eh, I shouldn't have to disable VDC to make a somewhat rushed left turn.

Just to elaborate, there was no traction loss and the clutch was fully disengaged. The car just kind of fell on its *** for a few seconds, then surged forward.

It was without a doubt an engine management issue. The management and engine (other than intake/exhaust) is stock. I agree that some sort of torque management is to blame.

It's a lot like what other people have described here.

Definitely an eye-opener.
