    Hello,

    after one year of testing and experimenting my multifunction gear indicator for the Stelvio is ready.
    It uses an integrated chip (made in USA) to talk with the motorcycle ECU, as well as a microcomputer to drive the display and collect data.

    It shows:

    - current gear engaged
    - engine (oil) temperature
    - RPM
    - current speed as digits and with colored bands
    - gear usage statistics
    - Kmh / Mph converter

    Also it has quite powerful spot led that can be turned on by simply keeping the clutch lever pulled.

    A lot of work but I'm satisified.
    Ok, it has not a cool/fashion style like my iPhone... but it works damn good in my opinion. :cool:
    I've got inspired by the rude instruments used in the offroad/rally world.

    What you think about it? :mask:

    BTW, here a (poor-quality) photo about the gear-usage statistics:

    Here the menu-system that can be browsed by pulling the clutch lever and/or by rotating the throttle:

    Looks good!
    Obviously a lot of thought and work gone into it.

    Wouldn't want one personally (my Stelvio has a Speedo, Tacho, and Oil Temp Gauge) but I bet there are many that will.
    I'm guessing if you could adapt it for GS1200s, you'd sell a warehouse-full :D

    Thanks John.
    I like it because the device is mounted close to the line of sight. This means that I have increased my safety during driving:

    1. I have not to move the head and eyes down to the dashboard (eyes/brain needs almost two seconds to focus the view on a different target)
    2. I don't need to read the speed, I just look at colored bands. (Again, the human brain needs a fraction of second to convert the image of a digit into his meaning)
    3. On a winding road, knowing what gear is currently engaged increases my awareness, and avoid to change gear in the middle of a curve (this can make your tyre slipping).

    Here, where I live, the speed limits are everywhere, this was making me stressed. Using the indicator I feel much much more comfy! But this is just my personal opinion.

    Selling it to the bimmers? Mmmmmmh... I would avoid if I can. Because, for the first time, a Stelvio could have something that a GS cannot offer! Hihihihihihii... :D

    Guzzi forever!!! :cool:

    So what would this cost and how difficult would it be to install?

    It's about ~$200 or so plus shipping. I'm letting him post here to see if there is interest, and I plan on selling them on the site here if so.

    What about Soul, passion, involvement, Italian style and flair, and not looking like a reject from a Transformers Film set?
    That's more than enough for me! ;)

    No drills, no cuts, no welding, no special tools.
    Just plug it to the OBD and headlamp connectors.

    If you don't have "small" hands (like woman does) the most "difficult" part is could be to route the OBD cable to the plug under the seat through the fairing.
    Usually I mount it in 15 minutes... :cool:

    Would this work on a '13 Griso also?

    Probably yes, with 99,99% of the probabilities. Since they mount the same ECU there should be no problem. But, honestly, I didn't make any test.
    The most challenging part is to find a suitable power connector in the original wiring, as well as to design a specific bracket.

    The style of the griso is unique so one should also take care of it. The shape of the gear indicator is quite rude, on the Griso would looks not so good. Maybe with a chromed suncover... mmmmh...

    Your obviously a man with good taste, your concern of it looking "right" on the Griso is also a concern of mine but it sure would be nice to have a gear indicator. My cali and F800 have me spoiled.

    Most probably I will work on the Norge 1200 and Griso 850-1100 at the end of the summer. I'm full of work and zero free time :cry:

    Hi Zerkaulen,
    the inner part of the display is flooded with a special resin to protect it from water, dust and vibrations. Also, the resin offer a solid protection against direct hits and increases general robustness.

    Last but not last, the plexiglass window is made in England with a special anti-reflex treatment. Otherwise you will see absolutely nothing in a strong sunny day!!!!

    Are you still sure that you want just the inner electronics? I don't recommend it... but if you really want...
