Gas Pedal Delay

FWIW I ran with open fang vents and it didn't do jack for my problem.

Ha! So it was definitely not related, but I guess it's safe to assume 220F is when power starts cutting. Yet, I felt the lag past 190F. I will test low end response and heatsoak after getting the car back.

I felt the lag as low as 180 - 190 oil temps. Don't think it was oil.

Indeed. Regardless of oil temps I always had the lag/no power below ~4k issue.

Power in general was greatly reduced with oil temps running in excess of 220*F. On a hot summer day driving the Z almost felt like driving a Civic... it was just dog slow.

I believe they are two seperate issues. One related to ECU/VVEL controls and the other a byproduct of excessive heatsoak.

In comparison, my Mustang barely breaks a sweat when it's 105*F out and I have the A/C blasting. The two cars are like polar opposites when it comes to temperature sensitivity.

If it helps, since I've switched to the Nismo, I've noticed a very small lag in high temps with it as well but it does exactly what Digi described above. It cools down very quickly. I've done no mods to the car other than audio. I do plan on CAIs soon so I'll post if the small delay I notice decreases any further.

Started noticing this problem this summer. I have a Nismo

Wow. I 'd be REALLLLY p*ssed if that was happening with the Nismo.
Only thing I can say is what I said before: report it to Nissan. Not that it affects me anymore anyway.
