    Astra H abs mk60

    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???

      Why not remap your oem ecu and save headache?

      Because the ecu was cheap and I wanted to see if it was possible.
      From what I can tell all I have to do is change the variant config in the abs ecu from z20lel to z20ler.

      It is possible. Have allready seen some but all ecus was reprogrammed to ler settings and last one which I remember didn't run it for long time he faced problems with engine
      If remember correctly leh and ler and lel had same ecu, sps it to ler and save money on ecu

      Already tried SPS the original ecu to change it from an LEL to an LER but it wont let you. Comes up with a hardware mismatch error. That's why I brought a LER ecu as I assumed it would just be a case of programing it to the vehicle.

      Yep tried all tricks I could think of to get it to reprogram but to no avail. Even requested a VCI code but they said it cant be done.
      Even if I had been able to program the original ecu to LER I suspect I would be in the same position I am now with the abs variant locked to LEL.

      abs only has an option to program not reset. When trying to change it to LER tech2win seems to check with other ecu's before coming back with programing failed.
      I just wondered if op-com, Vaux-com would be able to change the value. Will have to try and get hold of one and give it a try.
