Hi guys
I have a PRC PRB ECU running KPro v4. It was previously used to run my EG. I have just swapped it into my DC2 and I'm having a weird issue
After uploading a base tune for a K24, I started the car and test drove.
Vehicle drove fine and external wideband is reading correctly. ECU was running external wideband for years and has not changed/been modified upon install into DC2
No DTCs
All wiring in vehicle is correct
Only when going back into KManager did i find that the ECU is now registered as a PRA ECU.
I am now unable to upload a tune to the ECU as it fails.
I have removed the cover and confirmed the green light comes on for a second and then off. Red light then does one big flash and turns off.
KManager shows the ECU as online. USB driver appears to be at latest version
I have managed to erase the ECU but cannot upload a new tune
I do have a PRA ECU with Kpro v4 that was originally in the DC2. This still plugs in and operates as it should using the same PC/KManager.
Any help would be much appreciated
Damaged board? PRC/PRB showing as PRA
Re: Damaged board? PRC/PRB showing as PRA
What is the serial number that is on the K-Pro board inside the ECU?
From Help, About, what is the version of software you are using?

Re: Damaged board? PRC/PRB showing as PRA
Have you tried swapping the K-Pro from one ECU to the other to determine if it is the K-Pro or the ECU that is the problem?
Showing up as a PRA has nothing to do with this issue.

I will swap the kpro board to the other ECU tonight and report back
Re: Damaged board? PRC/PRB showing as PRA
Issue rectified. Swapped boards and both ecus worked as they should. Swapped boards back and the PRC started faulting again
Found a laptop with an older version of KManager installed. Plugged PRC ecu in and it prompted to re-upload tune due to version difference.
Tune successfully loaded this time instead of timing out with an error/warning like before. So unsure what the exact cause was but both ECUs appear to be running correctly now
