I'm starting to think a simple multiplier on the torque message may work, and we don't really need complex control code.
Over on the Honda Insight forum there is a relatively easy "analog" mod for higher electrical performance by artificially decreasing the sense current in the phase current sensors. This mod tricks the controller into thinking it's not sourcing enough current to the motor and to increase output. Since ABS drops regen current to 0 in the motor, there's no change to the traction control system.
In the leaf, we'd modify the torque by multiplying by a scaler and sending the new message (with correct CRC) to the inverter. So it would be like receive 1 send 1.25. You'd still have a delay in power, but it would be less of a hit since you'd still be getting a substantial increase overall and the amount of time that the acceleration is limited is only like two seconds. I do like the linear pedal feel of eco mode in the 2011-2012 cars, and this would keep the linearity with a larger slope.
Thoughts?
