Yeah. It's got myself, my dad, and my mechanical genius friend all stumped

At this point it is really starting to like the ecu is smoked. unless can is shorted that is the only other thing mentioned under u1024. Sorry.

But can an ECU/CAN fail gradually?

Exactly... I know it is not unheard for a reflashed program to lose a couple ones or zeros somewhere. So maybe it dropped a portion of its program, but not enough to make it altogether quit, just enough for it to get confused.

if it is cracked solder connections that are causing the failure yes. does computer ram fail gradually? Just a catch all though it doesn't mean something else isnt wrong or something is overloading a circuit in the ecu that causes the failure, or there is another condition that is giving the ecu the same symptoms of sensing a communication error with the vvel module. that is why Nissan Electronics :shakes head:

You could replace the boost with a boost/ AFR, the one I have reads boost in a ring around the outside and AFR digitally in the center.

Kind of sucks that it seems like I'm the only person to have this problem.. Woohoo having a big expensive boat anchor in the garage.

Could be a bricked ECU or a blown VVEL sensor.

Have you tried flashing a "back to stock" ROM on there? Also, make sure the ROM file is the correct one for your ECU.

If the injectors are larger and the intake plumbing is different with your set up, it will run pretty roughly, but should still turn over unless bricked.

I've flashed it back to stock with one for my ecu... All it does is just crank. I guess I can try a VVEL sensor replacement maybe.

if you have a buddy with a 370z unmarry your cable, flash his with the nats disabled and see if it will start your car. if it does you need an ecu.

So I'm not quite clear on this. I unmarry my cable ( which is just to put it back to stock I think ). Find someone elses car and flash it, then see if my car starts? I don't understand.

Yes you take the ecu out of ur buddies car put it in yours flash the ecu with the nats disable box active so it can start your car and see if it works then you know your ecu was bad.

Then put thier ecu back to stock and go buy yourself a new one.

Oh ok I got it now. Didn't know you meant pull out a buddies ecu.... Now if only I knew someone with a 370 that I could do that with.

We can with mine tom but I'm not home... For a whilr yet
