Help! Can no longer read or write to ECU!!!!
Buddy wanted to clear a code on his 06 WRX. We have used ECUFlash and Rom Raider ECU editor many times on his car over the last 4 years.
I download his current map, save it. Clear the code. Worked fine.
Find out there is also 1 more code left, so I edit the map and go to upload it.
About 5% of the way through, an error message pops up saying that the ignition was turned off while uploading and memory data may have been lost. This is 5% in, so barely any of the map is on the car. It says to turn off the ignition, and re-upload the map.
So I do that, and not it cannot upload the map anymore. It just says:
SSM2 init
SSM2 init
SSM2 init
SSM2 init
SSM2 init
SSM2 init
SSM2 init
kernal get version
interface close
interface close
I can't even read from the ECU when I try that eitiher. So now his car is stuck with 5% of a map on his car and we can't do anything.
I double checked the tactrix cable, the green connectors, everything. We reset the ECU and it is still doing it.
Does anyone have any idea what is going on???
Edit: also, the fans are not turning on now like they normally do when the car is in test mode, even though the green connectors are connected

I think you might have ran out of memory in the ECU i heard the ECU's have a certain amount of memory and every time you flash a map onto the ECU you are using up that memory. You could have possibly bricked the ecu im not 100% sure though so dont hold it to me.
