Great work! Thanks for the formulas.

Sounds like a nifty tool. I'm trying to duct-tape the poor man's solution through my off-the-shelf scan tool generic. I may have found the PID/MODE/ECU for MG2 torque, but MG1 still eludes me. I'll keep bit-banging till something looks promising.

Interest to hear what else you find from your data.

Mmm, i did overlook something.
The combined max torque of the prius is 478 Nm.
The final reduction is 3.9 so the max torque at the wheels should be
1864 Nm. The ford focus for example: 158Nm with a final reduction of 12.8 in the 1st gear => 2022 Nm.
