More testing with timing tonight. It is getting better, lol. Below are some pics that show a Slot Machine 13.5 @ 40* on the can and the readout from my code. Then @ 45* on the can with readout. Finally I put an R1 v21s 21.5 @40 on the can and the readout. Now R1 always read lower on the can by 4-5*. And my Motolyser confirms that. Now there are caveats... The pwm gets in the way of the bemf reading so I have only been able to read at full throttle. Anything less and all the readings are way off. I'm still working on it, lol. But this is progress!
