Hi all, I have one leaf and love it to death but it is time I convert my old '91 miata over.
There are a few threads on here about trying to reverse engineer the can protocol to get more torque but I wanted to bounce a new Idea off you guys.
How would one think the leaf would react if it had 2 competing sets of PWM IGBT gate signals that could be swapped at an instant.
The idea is that you keep all systems intact and run everything as normal except when shifted into forward and the pedal pressed.
Then you switch the IGBT gate signals over to a ti instaspin or similar brain board that is also sensing the pedal but can drive the IGBT with free will. I figure you would need to split or have redundant current meters on the phase legs and pedal sensor as well as a 6 channel switch.
So thoughts? what does an IGBT do when all of a sudden there is no signal? what do we think the leaf will do when it is trying to keep the FOC correct but feels like the motor is running away? I would love to keep most of the leaf control system but not if i can't get awesome power.
