What is the stock mark?
Information on the D3 motor I found online suggested that the "Stock" or "zero" mark was 30 degrees mechanical advance.

If you don't want to use the optional 21-30 timing...try max 20*. If you want to use our setting...we were set at 23* on the green timing board.

I had a MMM motor 17.5T
I put the sensor on min (10).
Run boosted class.
With same gearing and ESC settings of my comp v3 motor.
it gets way to hot after 2 min 80 deg
I run in belgium on large nitro tracks.
changed the esc (gt2 pro) settings way down.
It had nice speed out of the corner but lackt top speed.
After 2 min the temp was 36
after 3min 45
Then 2 rounds later (40 sec) without fading motor stopt and started smokking like hell and the temp was 120.
So after 10 min run the motor was dead.

Did you change your gearing from a V3 if you ran one?

These motors are a torque based design now so gearing change from a V3 is a MUST.

Sorry, +20* sensor is optional....MMM came with +10* sensor standard (11* to 20*).

Most motors when running with timing should not have mechanical timing added. If the MMM is a torque based motor like the LRP X12 then run standard timing on the motor. so with a +10 sensor board standard in the MMM i would turn it down to -10. For gearing, a torque based motor can take more gear try around 6.0 +/- .5. ESC timing, be easy at first, add a little a time until the motor temp rises or you have sufficient speed.
