Holy moly. Premature product release, anyone?

Hey Semtex....mine is doing the same. Exactly as you described. Hmmm...when I talked to Sharif at the time I got my tune last week, he indicated the "bugs" were worked out. I think UpRev didn't catch this before releasing. I'm gonna talk to Sharif and see what his thoughts are.

Thx Niko. It just so happened that I was on the phone talking to Sharif about this when I looked at your post, so I let him know that your car is doing this as well.

They're comin' out of the woodwork folks....hopefully it's something simple

Just run in stock tune folks till you get a updated map to fix your tunes from Jared.

I asked Sharif about this and he said it won't fix anything. What he explained to me is that, from the sounds of things, the issue is with the UpRev ROM, not any particular tune/map per se (which is why so many people are experiencing the same issue). When you get your car tuned, the first thing that happens is that they flash in the UpRev ROM over your car's stock ROM. All the maps are contained within that ROM. In other words, you don't switch between ROMs. You switch between maps within the ROM. So even if we switch to an alternate stock map, if the issue is within the ROM itself as Sharif suspects, the problem will still be there. Or to put it another way, the stock map is still an UpRev stock map, not the one that came with your car. The only thing we can do, per Sharif, is wait for UpRev to fix the bug.

You have 5 maps normally. One of those will be your STOCK MAP. I had issues with my UPREV and I can switch to my stock map and my car was fine then. If you can switch maps, put it on your stock one and normally the problem goes away.

Also UPREV has access to the Stock flashes. Contact them and they will email it to you if you don't have one for a 370z. or Sharif needs to as he is a vendor for their software.

As I previously tried to explain, the problem isn't the map, it's the ROM. Switching to the stock map within the UpRev ROM won't do any good, as the bug will be present in any map that is hosted within the ROM (according to Sharif).

Yep, good idea. If the fix isn't forthcoming soon, this is what I'll have to do -- replace the ROM entirely with the factory ROM. Sharif said he's going to call UpRev on Monday to get a better idea of what's going on, ETA for fix, etc.

and how are we supposed to do this ?^^ Don't even know if the extra option tunes that come with it work and since the valet and theft mode don't there is a doubt the others do too.. :-/

Not really, you can take the map completely off and revert back to stock.

You're assuming he made a backup of my stock ROM. He didn't. He said it would have taken an hour to do that via a ROM dump.

I have made many dumps of my stock ROMs as I had the full tuner version of the software. It only takes less than 2-3 minutes to pull it off the ECU. Not an hour. Sounds to me like Sharif is making excuses. Call UPREV.

I don't know if Sharif is making excuses. Heck, for all I know, I may have misunderstood him. It's really immaterial at this point -- the bottom line is that he didn't make a backup of my ROM, so worse come to worse, I'll have to get UpRev to send Sharif a copy of my factory ROM and have it flashed in. (I don't have my own license to the software, so I'm dependent on Sharif to flash it in. I didn't figure I'd have any need for my own copy.)

Having said all that, I don't think the problem is bad enough to make flashing my factory ROM back in absolutely necessary. Basically, the throttle is a little quirky on cold start, and the problem goes away within 2 mins. It's not like the car is completely undriveable or anything like that.

When I switch to the stock map I still seem to have the problem.

caneman88 · 11-01-2009, 09:46 PM

I looked up the maps and i don't seem to have a stock map
Uprev said last week that should have a fix real soon.
If I were to guess I would say it would be within the next couple of weeks
