I spent some time last night trying to find a message indicating the number of regen bubbles to help shed some light on the regen reduction riddle. I failed to find anything that directly correlated 1:1 with regen bubbles but I think I found something better. CarCan msgId:260 d:1 appears to contain available regen. I put a watchpoint on it in my CANary for my drive this morning and saw that regen bubbles appear when this message reaches 6, 12, & 18 (I presume I would have gotten the last bubble if I was able to reach 24). There is hysteresis so the bubbles only disappear when it falls to the threshold below that (the 2nd bubble comes on with 12 and off with 6; similarly, the 3rd comes on with 18 and off with 12). Should be illuminating to plot this along with speed, SOC, and temperature throughout the last year. I hope to do that tonight.
