### Run Information

    For each associated log, describe what tests were performed or whether they even contain useful information (turning on the car for 10 sec creates a log but isn't necessarily useful).

    Log 1: ~6 or so laps with a couple likely motor controller errors. Foggy cold driving around 10-11am. LV voltage low is a likely culprit for MC errors.
    Log 2: Restarted car after flashing regen firmware. No noteiceable difference in driving after regen according to driver (Daniel). Let LV battery charge a bit, drove it off to test regen and then off the track. Then let LV battery charge more while writing firmware to fix LV reading on dash and look at regen data. 
    Logs 3-5: Regen testing with random param stuff
    Log 6: Realized you need charge curr and negative torque to do regen
    Log 7: Back to normal to drive off track
    Logs 8-10: Random stuff testing
    Log 11: Regen probably working.
    Log 12/13: Are each a slow lap around the bleachers. Setting regen higher afterward
    Log 14: 2 laps with strong regen. Not great for driver and weird pedal mapping. Wheels locked up sometimes nice and linearly, sometimes its kind of random.
    Removed regen firmware and flashed traction control firmware instead
    Log 15: tried traction control but very weird (torque mapping at really low speeds is odd)
    Log 16: Added traction control minimum speed based on motor rpm(?)
    Log 17: Working traction control (1x power)
    Log 18: Stronger Traction Control - 2-4 brenner laps, pretty hard (4x power)
    Log 19: 2 Daniel laps to heat up acc, RTD kept tripping at full throttle
    Log 20: Continue warm up, tried Jack's latching fan logic, but it didn't work
    Log 21: More laps to warm up, then sit still with fans at full to cool down
    Log 22: Switch to regen instead of TC, RTD still tripping, BMS fault
    Log 23: Double amount of regen. Insane amounts of sliding, bad spin out, BMS fault
