I just got my Accessport for my 06 Base Z. Flashed the Stage 2+ map to it... No problem. Ran my car on a dyno, and found out that I'm running a little lean, so I went to tweak the map a bit. Saved, uploaded, datalogged, repeated til I got it about right.

Was uploading the final map, it got about 40% complete, then got a communication error... I told it to retry, then I get a Fatal Error. Says to contact support, which does not provide phone support anymore... Please help. I can't get the car to start, and attempts to reflash/uninstall are unsuccessful

 

I think you may have fried the ECU

 

Really? dammit!!

 

Sucks, but I cannot understand why someone would use a product that even the manufacturer doesn't want any part of.......just my .02.


That said...I hope you get it sorted.

 

This is what worked for me (Uprev, not Cobb) - disconnect the battery for a couple hours, hook back up and try flashing again.

The actual recovery has alot to do with the flashing software so I don't know if AP can recover the same way as mine did. Worst case, you should be able to send Cobb your ECU and they can manually flash it on a bench.

 

Thanks, I'll give that a try

 

Didn't work. unplugged the battery for the last 5 hours, and no luck. guess I'm fukked.

 

Any other suggestions?

 

Looks like a new computer is in order. Ouch1

 

I was hoping it wouldn't come to that...

Wonder if Cobb would be able to do anything. I emailed them.

 

Id call, email etc...8 times a day till they offer up a solution!

 

Thanks. I'll give them a call.

 

In the interests of helping out ex-Cobb owners and because they are good guys, UpRev may be able and willing to fix your ECU for a small fee. If Cobb lets you down, it's worth a try I guess...

 

Thanks. I'll keep that in mind.


Update:

Just got off the phone with Cobb. They just gave me a ticket number, so I can send the ECU in. So, now I gotta figure out how to get the thing out... lol. Wonder how much this is gonna cost me to do.

 

To get the ECU out? Just a little time.

 

Do your fans run at full speed when you just turn the key to the on position?

 

That's what mine were doing when my Uprev flash crashed. But luckily it recovered on it's own after leaving it off for a while.

To the OP, Cobb should be able to recover it on their bench. And if possible ($$ wise) I'd switch to Uprev once you get it back. Cobb has dropped support for our platform.

 

Yes, they do



Thanks, I'm actually considering going to Uprev now... I was originally going to go that route anyway, not sure why I didn't...

 

Well, just for giggles you may want to check the ECCS control fuse in the distribution block by the battery, but when those fans run full time like that it usually means there is no communication with the ECU.

 

Anybody know an easy way to get this ecu out? I'm kinda having a tough time with it. Looked in the service manual and don't see anything useful in there.

ok, I'll go look.
