Year and model of vehicle and the ECU you are talking about might help.

Engine ECU for GEMS Keith. Plenty to choose from. https://www.ebay.co.uk/p/Range-Rove...rol-Unit-ECU-ERR6645-with-Warranty/1525250362 Putting the security code from the ECU in the BECM may help.

My thoughts too. Could be a connection somewhere? The ECUs are pretty bullet-proof.
Not played with the GEMS much but you should be able to read the engine security code from the engine module and then compare it to the value stored in the BECM module.
