1969 Spitfire conversion using a Synkromotive DC750 contoller on a Motenergy ME1002 motor with a 2011 Chevy Volt battery pack converted to 180V, 90ah. Controller cuts power intermittently before reaching 3,000 RPM, then it takes off smoothly even with full throttle. Every gear it is the same jerky start until 3,000 RPM and then it will take full throttle smoothly. It does not appear to be hitting any software limits that I can see, but the controller seems to hit some limitation and cut power for one to two seconds, and then back to full power, back-and-forth until it reaches the magic 3,000 RPM. Any suggestions?
