That's awesome! Is it an IGBT module approach like Jack Bauer? Having the LEM current sensor be sort of the center of the design was one of the best decisions I ever made. It allows almost instant hardware overcurrent protection, and doing throttle proportional to current cures all the jerky starts, and Curtis whines, etc... It sounds like the Logisystems controller went the Analog route. I still don't know what the heck an op amp even is. I really need to read a tutorial on that. They sound important.
