well does it cut out at the exact spot where vtec engages or not?

move vtec up and see where it cuts out

 

Well i still haven't had a chance to put in that wideband, it's still in my brothers turbo 350z from tuning a basemap for it.

But i tried loading a stock tune and swapped to stock injector and it still does the same exact thing. It does it just revving the engine, partial throttle, full throttle, everything. I know it is something mechanical so any other input would be appreciated. I think the only test i haven't done yet is putting a mechanical oil pressure gauge on the front port by the vtec solenoid and checking for 60psi there.

 

Yes, whether i set vyec at 4500, 5000, 5500 it does the same thing. I might try to find a vtec dizzy, I'm using my non vtec dizzy with a leg cut off, ghetto old school way of doing it but i know that still works that way..

 

 

Does that mean you hold an answer? If not then kindly refrain from posting.

Would having no o2 sensor cause this? My buddy was actually having a similar problem, we thought it was because sometime wired in vtec wrong but he put in a rear 02 sensor he was missing and now his vtec works fine. I have mine disabled but it has nothing plugged in, it probably won't help but it's worth a try.
