Here's the result of of the last test I did at 30° timing:
A = 19, B = 18, C = 19, Average 18°.
RPM 18630
KV = 2300
AMP = 1.1
U = 8.1

This was with 2 shims. The addition of an extra shim brought the average up to 19° but lowered the other numbers.

I have a second motor of the same kind and am trying to match them as closely as possible.

Any thoughts or tips?

Thanks in advance!
