370z Ignition cut at Full Throttle

BGTV8 · 05-17-2018, 04:47 PM

What revs does it happen at (or any RPM)

Sounds like the ECU thinks you have hit rev-limit for some reason

If you have hacked the canbus and are still using the OEM ECU, you are into test-pilot territory

The car ran fine last year. All we did was install a fuel cell, require the lighting and tune the car. Tried to find a stand-alone ECU, but there doesn’t seem to be anybody out there that says “Yes, we have the solution”. Seems with VVEL, there is no way to ditch the factory electronics. The problem happens after about 5-7 minutes after starting from cold, and it happens at any RPM. It’s definitely not a limiter, it’s a complete CUT. If you plant your foot, she shuts right off.

It’s a shame, this car is so capable on track. It routinely eats E-46’s, many mustangs and some vettes, but right now, we are on a ledge ready to jump off.

Spoke with one of my tech's from work & he asked if you installed a one-way check valve vent for the fuel tank?.....he then added to try & run it with fuel cap off-say's it sounds like it's pulling a vacuum on fuel system; though i emphasized that it's like turning ignition off when WOT is achieved.
Don't Jump...it's not worth it....i'm sure you'll find it soon.

The car has a fuel cell with all of the requisite ATL lines.

If your really looking a stand alone there is a solution now. Contact VitViper. He has a Motec set up for our platform.

What he said ........

I have an M150 Motec running my OEM VQ37VHR engine using the VitViper package.

I can provide a patch harness to connect the M150 into the OEM harness for an M150 running Vitaly's package if you require.

What was the package price of this solution? Was it plug and play? How much post installation tuning was necessary?
