Oops, I was posting in the wrong thread...
So I finally got around to flashing my controller and display with the latest firmware.
After flashing, resetting to defaults and loading back my config, I also did a couple of auto tunes on the motor.
Now the motor runs really rough when starting. If I roll on the throttle slowly it will smooth out, but if I pin the throttle fast it will jerk violently before stalling and stopping.
It seems like it's having trouble with the initial square wave part of turning the motor. I tried turning off square wave boost, adjusting boost current, played with acceleration limits and nothing seems to help.
I tried playing around with the throttle curve and voltage limits but that didn't help. I should also add that the problem is more pronounced when using higher power modes.
I ran some diagnostics and got the following results:
This indicates to me that the problem might be tuning related still, but I've played with many of the settings I know about without success. I'm wondering if it's related to one of the more advanced settings I don't know much about like the following from here:

Integration threshold - analogue of the halls angles for the sensorless control mode.
Interpolate halls - smooth change of the hall angle based on speed. Used for FOC mode
Interpolation start - the motor is always started from a discrete angle, if digital halls are used. After the specified speed, the angle starts to change smoothly.
The only other thing I think it could be is the hall sensor angle setup, but every time I've messed with this in the past I've ruined it completely and had to revert to a backed up config to get it working again.
Any idea's?
Cheers
