Trying to use the Prius Gen 2 Inverter like a VFD w 3PH open loop motor

I can get the motor to just spin at a very low RPM's using opmode 5 sine. Using the sine mode as it is open loop. I have no idea how to speed this thing up. input is from AC rectified to 200 volts (I can go higher 300+ volts if need be)

I have tried numerous different values in the parameter boxes. I feel like I should try a earlier version of firmware? I saw Damien fire up a motor with the blue pill but how?
Any ideas where to move?

Prius Gen 2 VCU with 4.97.R-sine firmware

I'd think you need to set more boost, like 5000 or so.
Then try running in regular "Manual Mode" and increase fslipspnt in steps of 10 Hz or so.
