Ok, so I got my stage 3 ECU... Installed the FPR and plugged in the ECU, everything worked fine no CEL or anything. I started to drive went down the road a ways dident even get to see a full boost when i came to a stop light.... my car cuts off. I plug back in the stock ECU drive home and try the maptun again. it works for 20 seconds.... then stops. the stock ECU will still work but the after the fist time the maptun one cuts out it wont even start. I took it to a saab dealer to see if they could use Tech 2 and fix it. It did not work, he said the new ECU would not work. In addition to this my curent ECU i found out is EU spec. I dont even know where to begin... i just want my damn ECU working.
