Not sure what I was thinking about the cable I ordered. Both ends were wrong which makes sense as it's a cable to convert BMW diagnostic to OBDII.
Anyway I can confirm that the GS911 Wifi 100% works with my '17 GSA. I used four wires to temporarily connect the pin from the OBDII connecter to the GS911. Had to experiment a little to find Can high and low of the GS911 wifi but once I figured it out it worked just like it did on my '15 GSA. I was able to reset the service reminder and scan all modules for faults. The Iphone app doesn't work worth a crap but it didn't work much on my '15 GSA either. The windows software works 100%
I will be making my own cable as I don't think one exists at this time with the proper female connectors. Is it possible to get a BMW diagnostic plug some place other than from a totaled bike or a dealer?
The pinout conversion is as follows:
OBD pin 16 to GS911 pin 6 (12v +)
OBD pin 4 to GS911 pin 4 (ground)
OBD pin 6 to GS911 pin 7 (can high)
OBD pin 14 to GS911 pin 9 (can low)
