    rapidbike evo dorsoduro 1200 quickshifter

    i own a dorso 1200 from 2011.
    I own the bike for 3 months now. This is mij 5-th aprilia. (rsv mille 5x and Ducati multistrada 1000ds, yamaha, honda etc)
    the bike has a rapidbike evo tuningsbox installed. Riding is a lot off fun.

    I am thinking off installing a quickshifter.
    anyone know how 2 do that with a rapidbike evo? Is there a connection for?

    ciao

    Check their website. You might need a separate box that connects between the Evo unit and their strain gauge / pressure switch.

    You might also have to make your own linkage for it.

    Rapid bike is junk IMHO. JUST some thoughts from your forum dyno tuner.

    the whole basis of their tuning theory is that stock narrow band lambda/oxygen sensors can be used for tuning accurately. They cannot as the are only capable of detecting 14.5-14.9 or so af/r period. I’ve seen more bikes run better on dyno removing that junk than adding it, usually quite to the shock of the bikes owner.

    While my experience is limited to Guzzis equipped with said gobshitery I agree wholeheartedly with the opinion expressed above.

    They do offer wideband kits as well.

    There's some trickery possible with the narrowbands, as O2 sensors are meant to operate in tandem with a catalyst - those require oscillating periods of rich and lean running, which means the lambda will also oscillate in output. So counting "zero" (mean-value) crossings and accumulating integrals on either side of it would give a reasonable approximation of the AFR in a typical range experienced on an engine running in normal trim. Which funnily enough is exactly how a closed loop ECU trims fueling over time. The problem with those is they're usually set to target excessively lean conditions. Sensor calibration (temperature, malfunction, age etc.) could be a problem, though, more than when used for simple binary rich / lean signalling.

    Any DIY setup is going to be no better than the person DIYing, and if the base map supplied by Rapidbike doesn't match the bike then you're going to have problems from the start. Same as any remap.

    With certain software unlocks of UCU’S you can literally plug all but one wire of a wideband into narrow band sensor ports, set af/r tables and nail it, once dyno tuner this way I’d suggest removing widebands as 400 hours in pretty ideal conditions and using clean fuel is about expected lifespan, add lead to fuel and that number drops fast. I keep one lambda wideband separate from rest in my collection, is for leaded only and it costs more to use but I’m logging its lifetime. It’s just a standard Bosch LM2 series unit. There is no such software for thev7SM computer YET. In the Dorso 750/900/1200 they run closed loop with no air injection about 90% of load range. This is why I prefer FatDuc or similar variable resistor for getting them to say a 13.5 af/r baseline PRE CAT if still cat equipped

    Micah, quick question. I bought a DD 1200 with FatDuc installed. Rather happy with the fueling currently, but would like to replace the stock cans soon. Can I expect good plug n play results in your experience? Or will I need to consider tuning/remapping....

    Plug and play. Exhaust takes away weight but it would take headwork and compression and cams to REALLY make power of fuck up the tuning.
