Mms measures stator inductance.

Just buy one of these.

I think what we can all agree on, is:

1. None of the motor manufactures put their neutral (0 degree) timing in the same place, and
2. Even if they did, the pickup board variances mean there is extreme difference between one motor to the next (assuming the motors are the same), and
3. Every individual motor has a sweet spot where you advance past and the motors amp draw skyrockets and the motor stops making more power, and
4. That Trinity piece is pricy. So is the rotor checker. So is the inductance meter.

If I cared that much and had unlimited budget, I'd own a rotor checker and maybe a dyno. Heck, I might buy one anyway. I bought every other darn thing.....
