I have a serious engine problem
 

serious, as in time sensitive

Car ran fine all day yesterday at ZCON autocross. This morning it has no power at all. It will rev all the way to redline in first gear, but I have the scan gauge hooked up to it and I'm not getting more than 15% on the TPS reading with the pedal all the way down. Have the battery disconnected now for a bit, then John from Z1 is going to hook the Osiris up to it in a little while.

I just hope I don't miss the track day tomorrow :(

oh yeah, no codes, no CEL

Have you tried to reset the ecu?

Good luck with this, let us know what happened and how you fixed it

Only by disconecting the battery for an hour. No joy

Good luck with the fix, Mike

Weird, Mass airflow problem???? Good luck and keep us posted.

What is your oil temp/ you might be in limp mode/ or it sounds like the MAF do you have aftermarket intakes?

Mike, you dont have to unplug it for an hour, you just have to unplug it and pump the brakes like 5 times. Sounds to me like an ecu glitch that will fix itself.

nope, nothing that easy.,
Fortunately, being at Zcon, I had the best minds from Z1, Forged, Injected, UpRev and Nissan Motorsports working on it, and noone has a clue what it could be. On one data logging run that Sharif did, while in second gear, it kept cycling between full and reduced power, leading the guy from UpRev to believe its a problem involving VVL, and that its probably a loose pin in the harness somewhere.

We reflashed the ECU with the stock tune, reflashed it with another Z1 customers tune and reflashed it back to stock. Did the accelerator pedal reset procedure, did the TB reset procedure and a few other things and nothing works.

Its gonna have to go the dealer and get hooked up to the consult-3 to go from here, but its not even throwing any codes. You would have thought they would have the consult at Nissan HQ, but apparently, they aren't allowed to have any tools there.

its back on the trailer, going home in the morning, no track day for me :(

On the bright side, I came in 9th overall in the autocross, and on street tires at that. Yoko AD-08s rock! They really behave like R compounds.

Sucks to hear you had to miss track day. Please post the solution when you've got it. You never know who could be next.

That sucks man, I hope it works out for you!

Good luck with finding the solution

Not going to miss the track day!!!! Sharing my good friend an zdayz CEO Bryan Settles beast of a 350z track car. It doesn't even have a dashboard!

Good luck. Sounds like the TPS crapped out or has a short.
