I weigh 170lbs again
I was up to 177lbs after vacation because I was eating good but now I'm suffering killer jet lag/sickness and am back down to 170lbs... grrr I'm 6'1. Call me 175lbs geared up to ride. I'm living on anti nausea medication right now, might have the flu or just really bad case of jet lag, I hate going West to East and I'm doing it again next week going to Europe for a week.
Found out something really interesting about the controllers I'm using and a problem I was having at low speed after doing the shunt mod. Turns out I was running 102A battery 80A phase. The EB3XX controllers are different. Prior to my shunt mod I was pulling -15ish amps on regen using setting 2, after the shunt mod dropped my shunt to 0.52x mOhm I'm still pulling -15ish amps on regen setting 2 instead of getting stronger as in previous models. Controller expects a 1.5mOhm shunt for software to be accurate so now I triple the battery current setting to figure out what I'm really pulling. Tested this tonight. 20A battery current = just over 60 amps.

, maybe others know this info but I didn't. Set phase battery amps to 60 (programmed it for 20A) and phase amps programmed to 100A and my low speed take off problem was gone and wheelie city was back. 1:5 ratio battery to phase current and this thing is an animal on just 60A battery 100A phase, a lot smoother too. I'll have to try upping the battery current to see how it effects things.
I was so busy testing setting troubleshooting this problem that I forgot my temp probe until I was done, but ran an grabbed it as soon as I realized the controller was warm so about 1 min between power off and temp readings.
FET Temp 48C
Ambient Internal temp 55C
FET temps were dropping faster than the ambient internal temp which was dropping much slower.
Hand on the cover motor temp check, slightly warm, even 10 mins after shutting it off
I tried different settings and was up to 102A battery current at one point again. Went back and edited my posts on phase amps.
Videos will be tomorrow or Saturday now that I figured out this last issue. Gotta get my rear brake installed tonight, I need it desperately.
