hei + crank position

Post by Toymg »

Hi all,
I am curently working on fuel injecting a 2 stroke kick start only bike, and so far my plan is to use a gm hei module to give me instant spark and hopefully sync, my question is can I run a 12 tooth wheel for more accuracy and a single tooth wheel( to trigger my hei)
will this work to get my first revolution spark without sync to light off my "prime pulse" and hopefully everything will then sync up and run? please help as this is keeping me up a night and my wife is getting sick of it... Thanks Blaine

That hybrid approach could work; keep in mind that you will want the 1 tooth trigger to come in at your lowest amount of spark advance you'd run.
