Hi everyone!
I have a controller but I'm struggling to find the exact software needed to program it.
Controller model: Edrive EC1922A07 (i uses APT protocol).
I need to modify the startup characteristics and the current (Amps) relative to RPM/throttle position. Since I switched from lead-acid to Li-ion, the factory settings no longer provide the performance I need.
If anyone has a confirmed working setup (the right software version and cable pinout), I am more than willing to pay for the information/help.
I’ve already tried a standard RS232 cable with no luck, so I’m looking for someone who has successfully connected to this specific unit before.
Thanks in advance!
