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

 

Jeff is awesome and successfully recovered my ecu and sent it back free of charge. 10/10 customer service.

 

Great to hear! What was the issue?

 

Great customer service, once they fucked your truck up! And people keep doing these tunes???

 

I honestly do not understand why why people do these tunes. Why? To get more pep in it? It is a Tacoma. When I want to race I drive my wife's RAV4

 

It's aftermarket for a reason....there's always a risk but glad there was good customer service. Definitely know the risks and read the fine damn print when you get this type of work done.

If you sign away liability for a bad tune or flash, it could be your problem.
