Hey guys.

During a flash, the uprev software crashed. My ECU is on safety mod and my fan are on. It's we flashed only 50% of the map...

UPREV support told me to ship to them the ECU. But i'm in France and i have a race in one week. So i'll never get it back before.
The question is:

Can you flash the ECU without UPREV ( like conventional flash by eprom), flash a standard map, then use again uprev ?

My tunner is afraid to crash it, because UPREV is maybe adding some table over stock, that the rewrite of stock map could not erase....

My race is august 3 and 4 , please if someone know if the ECU recovery can be made by a tunner ?

ps: already did the tips for ECU recovery with the software and it didn't worked.

Thanks a lot guys

 

not sure on what you are going to need.
but . you COULD buy.order a stock ECU. used or new or reman.
and get it there in time. and just flash it there and then.
good luck.

 

Can't find the same ecu on the market atm. And even if i find one, not sure it could work, because the licence is based on my ecu,

If someone know if UPREV is adding table to the ECU other than the stock ECU... That could help me a lot. If they don't add table, i just have to flash the eprom to a standard 350z map and then use UPREV again to flash my acutal map.
If UPREV add table to the ECU, this method will not work becaue we'll have stock table+ some rest of uprev table on the ecu

 

There is a lot more involved in recovering an ECU than that. If Rom Editor will not detect the ECU then yes you have to ship it to them to recover.

If Rom Editor will detect the ECU, then you just need to flash it again with Uprev to recover it.

I think your best solution is to find a replacement ECU (does not need to be exact same, just matching engine/trans) and flash it with Uprev to disable NATS then just plug it in. Explain the situation, Uprev will give you a new license

 

Shipping it to them isn't the only option.

HP Tuners can recover your ECU if you have an HR. If you have a DE, a dealer with a Consult 3 device should be able to recover it.

What ends up happening is UpRev uploads their own bootloader to RAM. On failed flash, it enters a temporary state of limbo (regardless of what UpRev says, it's NOT actually bricked). What this means is while a request for ECU identification will fail, an actual flash attempt would still succeed. The reason why UpRev doesn't allow you to flash after a failed attempt is because they attempt to identify the ECU, and if it doesn't identify they won't even try to flash. What they could do is just trust you know what file is compatible with your ECU and let you go ahead with it, it would save a LOT of people sending in their ECUs. EcuTek does it this way, HP Tuners does it this way, I don't know why UpRev doesn't. Maybe send them an email and ask if they'll add something in temporarily to allow you to skip the identification step and go straight to the flash.

You can also boot flash your ECU using Renesas's flash development toolkit if you have a little bit of electrical savvy. It's not terribly difficult to set up (there's a very detailed how-to post in this section and on RomRaider's forum), this is all UpRev is going to do when they get your ECU. If you need a binary file to flash I've got pretty much all of them.

 

Thank you for your answer! I'm going to test it tomorrow

 

If you don't have the right file there's nothing to test. You can't just use an OsirisROM file because they're encrypted. Again if you need a binary to do the boot flash, let me know.

 

My tunner have the original map from the ecu too. My first custom map 2 year ago was made without uprev, with eprom flash

 

Hey dude, we flashed it with stock ecu map and it worked. But now we have a licence problem.

It say : licence error 00..
Hope uprev can clean this up and give us the licence...

 

I don't know if this helps you in any way, but CTD Germany is a reputable 350/370Z shop. They'll reflash an ECU and return it back to you. Altogether in 3 days.
