Hello forum,
I am trying to collect engine data from above mentioned motorcycle using OBD.
I am using RaceChrono Pro.
The OBD adapter I use is a UniCarScan UCSI-2100.
With the 'device output' option of RaceChrono I found out, that RaceChrono connects to the OBD adapter but not to the motorcycle. Command "0100" fails frequently with response "NO DATA".
Here is a command snippet recorded with RaceChrono:
<--13:26:43.785 OUT-->ATZ\r
<--13:26:43.813 IN -->ATZ\r\nELM327 v2.1\r\n\r\n

In contrast to Racechrono I am able to connect to the motorcycle with the UniCarScan UCSI-2100 adapter using the popular app 'Torque'. 'Torque' is eventually able to find the right protocol of the BMW S1000RR, namely ISO 9141-2 (or ISO14230-4 KWP). Here is a 'Torque' command snippet, which I recorded:
...

137.628 0105< 41053A<<>
138.285 010F< 410F3D<<>
...
ATSPA3 forces the UniCarScan UCSI-2100 adapter to use ISO 9141-2 protocol, which my S1000RR understands.
So my question is: How can I tweak RaceChrono to use the right OBD protocol to connect to my motorcycle?
