I got my hands on one of those FLASH/CIRC company's scooter. You will need to replace control board, engine controller and accelerator, as no custom firmware or free board exists at the moment. That's not too bad as the assembly is not done well, during disassembly I've found many cut cables and an abuse of hot glue and tape. You will also want to remove the stupid LEDs on the bottom, too much Need for Speed Underground 2 for my taste. There's only one GPS module and GSM module, they are in the control board under the plastic hood, which also contains the antennas. I tried to power everything up skipping the control board but it was a no-go. I've seen that battery, control board and engine board communicate trough a RS-485 line, which receives his 3,3V from a conversion on the control board. There's an ACC cable going from Control Board to Engine Board but I don't understand what it means, I just now is shorted with the positive pole of the 36V battery. The accelerator is connected directly to the engine board, so the control board must give some sort of signal to the engine board to enable the scooter, through the RS-485 line, but I got absolutely no clue on what, how to intercept it or simulate it. Any though is welcome.
I would like to know what do you suggest as replacement engine module. The wheel with the engine has the classic 3 wires and the hall 5 wires.
