OBD engine diagnostics

Discussion in 'General Motorcycling Discussion' started by iolithblue, Apr 6, 2015.

  1. OBD has been standard on cars since 1994. i have a bluetooth dongle that connects to my android tablet, and lets me see all the onboard data live in my car.

    why cant my bike do that? does any bike have a OBD connection?

    Bikes didn't have to abide by the OBD standard so you won't find many with the car style connector. I think there are some Harleys & Triumphs with it, but most manufacturers use a prioritry connector interfacing using a K/L line (using the ISO14230/KWP2000 protocol) talking to specalised software diagnostic programs.

    Whilst K/L is supported on the standard car type OBD II connector, because most manufacturers have done their own thing as far as software its not just a simple matter of making a cross-over cable to go from the bikes diagnostic connector to the OBD II adaptor.

    You can get specialised tools for reading (some) bike ECU's from places liker Healtech or even the factory units, unfortunately you wont be able to use the more common bluetooth type OBD II units to have your engine diagnostics appear on your iPhone dash board. http://www.healtech-electronics.com/products/obd/
  3. Bummer. It's pretty awesome to see live data like air fuel mix, revs, coolant temp etc. Oh well.
