I checked the config of the controller config

motor-type=3
kp=03333 ki=00050
current-sensor-amps-per-volt=0080
max-regen-position=0042
min-regen-position=0339
min-throttle-position=0539
max-throttle-position=0837
fault-throttle-position=0005
max-battery-amps=0015 amps
max-battery-amps-regen=0015 amps
max-motor-amps=025 amps
max-motor-amps-regen=025 amps
precharge-time=0050 tenths of a sec
angle-offset=119
saliency=0000
pole-pairs=004
max-rpm=06000 rev/min
throttle-type=0
encoder-ticks=0256 ticks/rev
pi-ratio=062
raw-throttle=0501

Change current-sensor-amps-per-volt to 480

stream log data and check the throttle signal, adjust scaling of throttle signal, motor amps, pack amps

range is 1018 at 1k, 80 at 999k
max-regen-position=0100
min-regen-position=0450
min-throttle-position=0550
max-throttle-position=0900
max-battery-amps=0100 amps
max-battery-amps-regen=0015 amps
max-motor-amps=200 amps
max-motor-amps-regen=050 amps

The settings were saved.

run-pi-test2 was run at the following settings. See attached raw log file. None of the settings appear to change much, whether there is power on the DC bus or not, whether the kp and ki are large or small.

I see no convergence at all. Perhaps the IGBTs were damaged after all. BUT - with the old firmware and the settings from my siemens motor I got the motor to run (poorly) but it rotated!

kp=03333 ki=00050
kp=06666 ki=00100
kp=13333 ki=00200
kp=01666 ki=00025
kp=00888 ki=00012
kp=30000 ki=00600
kp=04000 ki=00064

Then I tried running the controller and there appears to be no AC output phase to phase, phase to B+, Phase to B-. Something like 0 - 0.7V but it is not consistent. It should be consistent. I didn't think to check the phase current to see if there was current flow into the motor.
