That's strange!
With all the bitching I did I don't think any of my threads were deleted?
I wouldn't bother with a new internal Magic Pie internal controller, it's not worth the hassle.
Get a infineon to match your batteries max continuous current, and some alpha eco wire 12 G and rip out that internal controller!
You will also need to get a throttle and ebrake as I'm not sure the GM ones will do!
You may need to request that the infineon be programmed for you including regen strength, or request that the cable be wired into the controller for you and program it yourself, it will be useful if you ever get a better battery or new motor!
