    Who's told you it's burnt out?

    There is a sticky on here somewhere of what to check when the car is not starting, I'd start with that.

      My mate has a auto electrician workshop I asked him to remove the Clifford alarm as I thought it had messed up further investigation he found a burned track on the ECU

        Just wondering... Do you have a Chinese alternator on your car? There has been a thread recently about an ABY ecu failing due to over voltage from the alternator. Just something to consider...

          Yes Chris 5044 has had a few troubles. He had his ECU sorted out . Maybe you could pm him ask who he used.

              I have a couple of spare ECU's, most from the factory were socketed so swapping the chips over is easy. Is the map sensor in your burnt out ECU a stock one, if so then it should be as simple as swapping over the chips. The brand new AAN ECU that's for sale on here would probably do the job too. No way to check whether it's socketed without opening it up though.

                  jamie9048 this is the thread that may help. It was likely caused by the voltage regulator on the cheap alternator https://www.s2forum.com/forum/techni...p-advice/page5

                      Quick update my ECU had become damaged and kept blowing a main fuse, it's been sent away and repaired.
                      I've also had a suspect Clifford alarm removed and the remnants of three other after market alarms removed.

                      I've drove the car for the first time last night and I'm not sure if it feels down on power as it's been 8 months since I've driven it in anger... I'm now wondering if the repair company has removed the chip from the ECU returning it to standard power.

                      Anyway I might soon get it dyno tested and think about a power improvement injectors and new chip and maybe a new turbo?

                      Any advice on freeing some ponies.

                      Cheers Jamie

                        Not sure who repaired it but I can’t imagine they had Stock S2 chips sitting about and fitted them to your ECU.
                        Pull the codes first, see if you have any faults the ECU has registered. Do you have a boost gauge? If so how much boost are you seeing?
