I have just been sorting through things and come across my old ecu for my Corsa. The code is PK. It still has EVO 5 chips in it, however I was having problems with it before it was broken. I suspected that it was the EVO 5 chip that was the problem but its been so long now I cant quite remember.
Only problem is I don't have the original chips to go back in, I don't have a car to try it on to test. It will be of some use to someone hopefully.
