I'm hoping there are some nerds on this forum with experience with the grin cycle analyst. I've been mostly pleased with the grin experience so far. Love the rich array of read-outs (TMI maybe) getting good over-all performance, efficiency, the regen is awesome, etc., I just can't seem to get it to max out the wattage.
So I'm running a RH212 with the fast-wind on a recumbent bike with the cycle analyst and the grin frankenrunner, and a 72v nominal battery. Only thing is i can't get more than 1500-1600 watts out of it, at any speed. When i plug these parameters into grin's motor-sim tool, it says I should get 1800 watts at 18 mph and I should be getting 2000+ watts from 25mph to 40 mph. When I'm accellerating, i'm climbing steadily to 1585 or so watts at about 15mph and then the power just plateaus there. Every once in a while i get 1600 watts, but never more.
The speed limit, amperage limit, and wattage limits are all maxed out. I thought it might be the throttle setting. I've tried playing with the throttle output and made sure it was 99% "Through" and the range goes from the maximum spectrum of .85v to 4.24v.
I understand that asking for 2000 watts is a little glutonous. I actually don't really want to go faster than 40mph and the system already does 40 with 1500 watts on flat ground, but it would be nice to have that 25% extra power for accelerating and for steep climbs. I'm hoping there is just a setting to change somwhere. The setup procedures are not super simple, perhaps i am missing something. Other than setting the battery specs and the wheel-size for the accurate speed read-out, and playing with the throttle setting AFTER noticing the issue, I haven't changed any of the factory settings.
I actually have the same issue on my other grin kit which is installed on a cargo bike with a 60v battery, which also should be peaking at 1900 watts at high speed, and again, i'm only getting a max of 1600.
