PIDs for yamaha

Hi,

Has anyone succeded in reading brake or lean angle obd data on newer yamaha motorcycles with imu?

It would be nice to have those 2 beside throttle position and rpm on screen.

I own tracer 9gt and rc is not showing anything regarding brakes or lean angles out of the box.

    That data might not be available through OBD-II, but through raw CAN-Bus only. Unfortunately my Yamaha T7 does not have IMU so I cannot help with that. My KTM 790 Duke has them on CAN-Bus, but cannot find anything related for the OBD-II.

    RaceChrono has only standard OBD-II "out-of-the-box" and it does not contain channels related to braking or lean angles or accelerations. They need to be added as custom OBD-II channels (proprietary to the manufacturer) or raw CAN-Bus channels (also proprietary).

    Here's what I found in the CAN-Bus of my 2019 Yamaha Tenere 700. I didn't create a Vehicle Profile in RaceChrono as I could not find speed after several tries. Not sure if it's a pulse count or something that cannot be easily done in RC.

    Packet ID: 20A (ECU?)
    20A 73 8E 0D 3F 00 01 17 02
    Byte 02-03:
    RPM
    Byte 05(04?):
    00=still, 01=rear wheel moving

    Packet ID: 216 (throttle body?)
    byte 00:
    22 == throttle 0%
    CF == throttle 100%
    Byte 05:
    Changes, maybe interesting?

    Packet ID: 22E
    nothing when engine not running

    Packet ID: 236 (Gearbox?)
    Byte 00:
    236 00 # neutral
    236 20 # gear 1
    236 40 # gear 2
    236 60 # gear 3
    236 80 # gear 4
    236 A0 # gear 5
    236 C0 # gear 6
    236 E0 # between gears

    Packet ID: 23A
    nothing when engine not running

    Packet ID: 268, ABS?
    Byte 03(02?):
    00=still, 01=front wheel moving
    Byte 04:
    00 = no brake
    04 = front or rear brake
    Byte 05:
    00 == engine not running, abs light on
    1C == engine not running, abs light on, off-road abs on

    Packet ID: 2A0
    nothing when engine not running

    Packet ID: 0x20A (ECU)
    RPM = (B2* 256) + B3) / 2.3

    Packet ID: 0x216 (ECU)
    Throttle = B0 (as you wrote)

    Packet ID: 0x236 (TACHO)
    Gear = B0 (as you wrote)

    Packet ID: 0x268 (ABS)
    ABS light
    (Hi nibble) = 0000b (light off)
    (Hi nibble) = 0001b (light on)
    (Hi nibble) = 0010b (light fast flashing)
    (Hi nibble) = 0011b (light slow flashing)

    OFFROAD
    (Low nibble) = 0000b (off)
    (Low nibble) = 1000b (on)

    Speed = B2
    Here need your help...

    The message ID 0x268 is sent every 10 ms and the Byte n.2 is the speed, but....
    It takes the values ​​0, 1, 2, 3, .... which correspond to 0, 19, 38, 57, .... [km/h].

    Now, the passage from one speed to another value is determined by the frequency of the respective raw data.

    Example:
    9 km/h (about 19/2) is obtained by alternating every 10ms the value 0 and 1.
    If the 1s increase compared to the 0s, the speed increases and if they are only 1 to reaches 19 (threshold speed for raw data 1).

    32 km/h is obtained by alternating more values ​​2 to the values ​​1.

    Can you help me figure out how to get a formula for correct decoding?

    P.S. I also found ECT and Air Temperature
