There are 3pin to 16pin connector adapters available, to connect a obd2 device and then use a app like torque pro, I have ordered a adapter myself, once I have mine, I’ll update here.

I have tried this and it does work. Important thing to note is which adapter you require. Is your bike a US spec or Euro spec? The Euro spec uses 4 pin connector while the US spec uses a 3 pin connector. You can tell by the part number printed on your ECU. 2WD is UD and BR5 is Euro

My ecu was printed 1WDxxx (Asian version) and 2WDxxx is for the ABS version. can you explain the specifications of your r25 / r3. year of manufacture and ecu code? and the connecting cable you use

@Scott - It does read throttle position. There is no brake position sensor on the bike to read from. No production bike that I know of has a brake pressure sensor.
@onnyprima - I am using the BR5 Euro spec ECU. Which adapter did you purchase and which pigtail did you connect it to?
