Check the version numbers on your ECU - I expect the one that works was a 59M and one that didn't was a 5AM and the wiring loom/pin out is different between the two; the sidestand is the giveaway I think!

All 3 ecu's were 59M.... The original one was the one that sensed sidestand and kill switches in wrong position and appears an internal ecu fault. That one would consequently not allow any spark or injection.
The other 2 ecu's which allowed one spark/injection appeared not to be communicating with the immobiliser although both were meant to be immobiliser disabled. Incidently, the immobiliser appeared to recognise the key as it extinguished the light iun the correct 0.7 second.
Cheers.
