Have got the correct one now so i guess i will try this.
Does anyone know:
If i take out my old chip will it work the same without a setup in the new ecu?

For the final time, you tried a working ECU off dannys car, it didnt solve your problem, it was then refitted to his car which continued to run.
IT IS NOT AN ECU FAULT!
