Finally going to start a thread on my Kelly kbl controller. Currently is interfaced with a cycle analyst v2.3(will hook up v3 later ) and a cromotor v3. I've had a few interface issues and some programming issues. Currently I'm in class so I don't have a lot of pics and a lot of this stuff is off the top of my head.
First issue: cycle analyst to Kelly hookup. I would like to wholeheartedly trust my cycle analyst but I fear I have not calibrated it well enough. I've purchased a 0.5 mohm shunt from Justin and have correctly inputted the Value into the cycle analyst. However I'm only seeing a max of 118amps even though my Kelly is set to put out 175 amps battery and phase. Any ideas how this is happening? I do have the motor noise reduction option clicked which makes me think it's limiting high current to mitigate the motor noise. As I understand it the noise is from high current going into the motor at low speeds in conjunction with the block signal the Kelly puts out.
Second issue: Kelly controller motor sounds. I've only noticed this after hearing other ebikes. In fact the old infineon controllers were quieter.
Greg put up a video of my cromo v2 in the 26" large marge making a obnoxious groaning noise. My Cromo v3 is now in a 19" Moto rim and still makes a relatively obnoxious grinding noise at low speeds.

Third issue: anyone with experience with Kelly kbl controller have any input on the correct settings?
The phase current is set as a percentage of the max controller rating (250a) and the battery current is a percentage of whatever the motor current was set to. I set it initially to 50% motor and 50% battery and felt fine. I put it up to 70motor and 100battery and have pretty much found no difference which is nuts since that would mean 17.5kw on a Cromo is not flipping me over. Ideas? Settings?
