Motor setup help please

I have a self built VESC 4.12 with 3.34 Firmware, Haiyin 5000mAh 20-30C battery, Turnigy SK3 6374 149 motor.

I can't get the Motor Setup Wizard to complete.

Please can anyone supply a set of BLDC Parameters that may work?

I have limited the battery current to 15 Amps for safety (is this a problem?) until I get it going on the desk.

I'm looking for I, w, D values that will work for this motor.

BLDC mode, I always get Detection failed, tried a few different values.

FOC mode, RL stage completes:
R: 13210.19 mOhms L: 23.11 uH
Motor spec says 0.021 Ohm internal resistance, so calculation seems to be wrong.

Please help

My current settings (IIRC, that same motor, but I"m not in the same room as that motor right now).... 

R: 16.0 mOhm

L: 16.63 uH

5.053 mWb

KP 0.0166

Ki 15.97

Observer gain: 39.17

If there is a version with a lower KV than the 149 that you have, then I probably have the one wiht the lower KV. Or maybe not if that one was out of stock when I ordered.

Did you ever get it working? I have a very similar problem.
