Ok so the story goes like this. wanting a bit more power I brought an ecu off ebay for a Z20LER 200bhp astra to fit to my Z20LEL 170bhp. Now the ecu programs to the vehicle fine but I get a trouble code U2108 replace or reprogram ecu" and no power. If I delete the code with engine running then all is fine and it goes like stink.
U2108 is a communication error with the ABS ecu due to the variant config being set to Z20LEL but if I try and change it to Z20LER it comes up programing failed Tuning Protected.
So the Question is does anyone know how I could change this. I've tried tech2win, solus pro and Bosch kts. would opcom allow me to change the settings???
