    I was updating the firmware and the pc quit working. No lights and computer will not connect to it. Bike wouldn't start until I disconnected the pc and used the stock ecm. Anyone had this problem? Thanks

    There was a problem with the cables in some cases.

    Had a problem with mine where the computer wouldn't recognize the pcIII.
    Tried plugging/unplugging cable and new 9v batt.
    Reloaded the software into the computer and fixed that problem. Had to reset the throttle position, but that's all. No problem after that.

    I've already ordered the new pcv unit and getting lcd as well. When the wide band commander and auto tune is released, getting Fuel Moto to send that also.

    So, in a little bit, I'll have a pcIIIusb unit I'm not using. Going to ask my cousin in Pensacola if she wants it for her '08 Dyna. If not, then I'm willng to sell (cheaply).

    Thanks for your input. My PC III does not even power up, either on the bike or with the 9v battery adapter. Any ideas?

    Since you were updating I am guessing you have previously connected so no worries with OS version or anything like that. Sounds like it may be DOA. Does Dyno Jet offer any diagonistics if you send the unit in?

    Thanks guys. I emailed Dynojet support and they said it sounds as if my PC III needs to be reprogramed. I can send it to them or I can take it to one of their service centers or I can buy a reprogrammer from Dynojet for $40.00. I will probably take it to the service center and get it checked to make sure it still works rather than buy the reprogrammer and then find out the unit is DOA.
