Actually, you seem to be overlooking the fact that a DIESEL engine does not
even require a spark.
To the best of my knowledge even the "squirt of fuel" is a mechanical
function carried out by the diesel injection pump, the timing of which must
be at an exact point in the pistons compression stroke.
So basically the on-board computer has little to do with running the engine
on a diesel.
