ADV2 Electronics Upgrade. The good-Bad-Ugly
So I’ve completed install of the V2 electronics kit for the ADV.
I found this kit is bitter sweet for these reasons.
-Safety. The kit is a safety upgrade the better protects the rider from voltage sag.
-Upgrade. In the kit Tony has included basically everything. He’s included a new ESC, a new
BMS a new front light, a new wiring harness, and two new frame parts that mount and fit all the new parts. Which also means you can save your old electronics for a rainy day.
-Cost. $200 is highway robbery for all of this stuff. Tony has to be taking a loss.
- Execution. This is probably different for everyone. My board had a rideable tune when it was first reassembled with the V2 kit. Motors are all a little different so a motor tune is necessary anyways. My board gave out during heavy braking at low speeds. The motor was loud and a bit rough at high torque demand and speed.
Tony helped me work through it for a bit.. and then seemed to give up. He thought I was having a failed hall sensor but I was testing fine.
Eventually I just tried tuning with Float Hub. Since it’s the V2 electronics kit for the ADV it’s hard to say which setup is appropriate, and without Tony responding…. Makes it more of a guess and check.
I’ve tuned the board a dozen times now in float hub, some time with the exact same settings as previous, sometimes trying different motors or ESCs or other values and yet I’ve got different results each time. My last tune I settled on the V2 motor and the early bird ADV2 ESC (which I couldn’t imagine is the ESC ive got… but it’s the best result..) My last tune feels the most comfortable. It’s the tune I’m now testing and hopefully will serve. It’s a little disheartening because the whole reason for the upgrade is safety but I have less trust in the board now than I ever have. I really don’t feel like the float hub parameters are correct. Mainly the ESC. But again, the the only tune so far to feel like I have appropriate power, my motor sounds good, I don’t click. So for now as I test and watch temps… this is the tune.
Other notes are that my detected motor resistance is slightly out of range measuring 89 ohms. This was not the case when I last tuned by board with the original ESC.
