Flame suit on- General MS ign problem
Hey guys, Im posting this here because through the flaming this is the most informative and helpful site I know.
Im helping a mate with a MSpnp (microsquirt based) AW11 install (series 1 MR2).
rather than use toyotas odd ignition system we are getting the triggers directly from the 2 hall effect sensors inside the dizzy. one on a cam and the other a 24 tooth wheel.
Heres the problem, Dizzy spun by hand or in drill (everything wired and installed in car here) and we get a great signal. ecu starts firing spark and fuel etc.
Dizzy 90% of the way in the dizzy opening, spin it with your fingers and we get good signal as above.
Dizzy 90% in, spun by hand, cranking engine, good signal everything fine.
Just that last 10% of the way in, let the cam spin the dizzy, no signal at all.
What the hell.
Any help or suggestions greatly appreciated.
