We are fitting another T5 engine in another Autograss special but we are having trouble getting a spark, does anybody know if the immobiliser is within the ECU and if so if there is an easy way to bypass it ?
The ECU part number is Bosch 0 261 203 851.
Any help will be much appreciated.

Yes, 851 ECU does have immobiliser, although it can be disabled.

The software in the ECU needs to be altered to make it ignore the immobiliser.
