Running a Phaserunner V6, GMAC 8T and Cycle Analyst V3. These were received as a kit from Grin. Several problems are observed:
1. Cut out on accelerate: When I accelerate from a dead start, often the motor will ramp up for a bit then cut out (does not respond to throttle). If I don't accelerate hard (go easy on the throttle), it doesn't do this. Letting off the throttle, waiting a bit, it comes back and everything works again. It seems like if I keep the power under 1000 watts it doesn't cut out on acceleration. There are no settings in the Cycle Analyst or the Phaserunner Suite that should limit anything to 1000 watts.
2. Cut out on e-brake: Finally got and ebrake and regen working after operating the bike for about 20 miles (with no regen, no ebrake) I was able to stop the bike well on gravel, even skidding the tire a bit. When I tried going down a large hill with regen braking, the motor and throttle suddenly became unresponsive. Eventually (after walking home) I tried disconnecting the battery and everything was again responsive.
3. Cut out on Phaserunner Suite test: Connected to Phaserunner suite software. Read the original Phaserunner parameters and saved the original parameters in a file. Changed the Max Regen Voltage Start-End to 42.5 and 42 V to match my battery. Otherwise stock programming as received from Grin and (presumably) tuned to a GMAC motor. Was able to run the speed up and down a few times, then the system started cutting out on acceleration. When I operate the throttle, The motor will run for a second or two, then it quits running and I get a "1-5" Controller Over Temperature error on the Phaserunner LED [EDIT] I was reading this incorrectly, it is a 5-1 warning "Communication timeout", and also a "Warning: Communication TImeout" error on Phaserunner Suite.
[EDIT] Currently Issue #3 is preventing the bike from operating at all - it will run for maybe 5 seconds then quit. First two issues were observed during about 20 miles of riding, then the third issue appeared and the bike is not usable.
I have contacted Grin, and pushing them for a return authorization.
