36-1 trigger wheel in a distributor....
Posted: Sun Nov 05, 2017 12:02 pm
So I have been working on a distributor for my turbo beetle project for sequential fuel and spark using a 36-1 trigger wheel to be used with my ms2 (after i upgraded my racecar with an ms3) pictures as they say speak 1000 words
that was at crank speed and so i tested at cam speed in megasquirt
also at cam sensor speed i was able to read 300 rpm quite happily.
my question is i was showing a racecar friend this and he was said that "It will work , but will struggle to get a perfect reading. I would say you will get 5 degrees of difference on and off throttle with the backlash of the distributor drive shaft. And another difference with the clutch pushed down as it pushes the thrust on the crank" now i thought that it would have a much smaller effect (around .5 to a degree at the cam ~ 1-2 degrees crank) at worst case i will add a crank sensor too
