I'd agree, you DON'T need the crankshaft position sensor (flywheel, transfer case and the actual sensor).  An input from the spark ignition will sufice (distributor? surely that's already on the engine).  That's
all you  need to get speed.  You can use timers to delay injector firings after the spark triger, if you MUST get complicated.

How can I get one of those cheapy Mini injection systems in Canada?!
