The problem with the EDC1.3.1 is that it will not accept the command from the diagnostic tool to sync until the engine has been cranked.
Basically you have to try to start the engine so that the immobiliser actually fails before you can sync the EMS.
The problem for me is that I don't have an actual car, just an ECU on the bench.
I have no idea what the criteria is for this ECU that it has been cranked. I am guessing that it will need to see movement from the crank angle sensor or something but this is not easy to achieve on the bench.
Really I will need a complete working car for this one I think.
