I'm not sure if you know this but you cannot run sequential injection with only an EDIS module as your tach input. You also need to add a cam signal. Otherwise you can only run semi-sequential injection since the ECU has no information on the phase of the engine with the EDIS signal.

By the way, even you were to not use the EDIS module and connect the 36-1 wheel directly to the MS3 you would still need a cam signal to run sequential injection. A crank-only signal is not sufficient for sequential injection (or ignition).

Each to their own, but I find a JimStim invaluable for initial bench testing - and repairing broken MS. If it didn't exist, I'd have built something similar.

Thanks for that - as I indicated it is a Thor engine so has a cam sensor as standard.
