Thanks AL, I'm prepared for it not handshaking properly but nonetheless, was the last option as u know.It's more serious than just matching up the wires/wire functions. These displays use a form of serial communications from the controller to the display and back. There are no standards set to define those communications, so your chances of an unmatched controller/display being fully functional are remote at best. Some will actually tease you with their ability to light up the display - and STILL not be able to communicate with the controller. I'm not positive on the Bafang stuff, but I am on the KT based equipment. If you want a display to talk to a KT controller, it had better be a KT display.... -Al
Crossing my fingers.
P.s. run 2 bikes with kt - kit and no issues so far. I think there's more valuable info readily available when dealing with KT.
wish me luck
