ECU BRICKED? Immediate help requested!

Requesting immediate help to fix this. I just flashed a valley runner tune and once complete it immediately started throwing codes. I drove it around the block and it won’t shift out of first. I tried to reflash it and it can’t even read the vin now.

 

If the motor is turning on, I don't think its bricked. When I bricked mine, it would just keep cranking. I could be wrong..

 

Disconnect battery wait 10 minutes reconnect try again

 

tried that. Didn’t work

 

VFTuner said it’s not technically bricked if it turns on. The big issue is i can’t even get the software to prepare the ECU now so i can’t fix this.

keep one thread for better consistent help.

 

I had a 20 minute phone call with Jeff from VR discussing the issue and he is sending me a new ECU and i will be sending him mine to diagnose the problem. Lots of possibilities but the current guess is a voltage drop. Il post updates as we learn more.

 

Cheers!

Looks like things are handled. Good news.

 

bumping this, i just had the same thing happen to my truck, truck is cranking over dead in the water wont start...

 

So....

 

I was trying to flash a Yotawerx tune just now. the tune file may possibly be vin locked. the flash failed and now i get the same error as the OP has above. Currently just disconnected batt gonna wait 10 min and see what happens. I have techstream avail if anyone can point me in the right direction to get my truck back up and running i can flash my other tune back.

 

you have to read the ECU first to get the vin to match. (surely you arnt installing another vin's tune) then flash

 

when i hit read ecu i get the error that the op posted now after the failed attempt to flash
