Low RPM fuelling issue

    I've had the full fuelling upgrade for 2 years now with no issues.
    However for the last month have experienced major hesitation at low revs, particularly upon take off from traffic lights.
    This problem only occurs after approx 15-20 minutes of riding. Requires a good screw of the throttle to clear and occasionally slipping the clutch to keep revs up. I've been advised by a specialist that Power Commanders can drop their program after a couple of years.
    4 tanks of different brand fuel have been tried.
    Any similar experiences or feedback?

    I take it you didn't back up your power commander maps? If you did, restore them.

    It could also be your Autotune. Try clearing the settings in this, and start again. I've done this on a few occasions.

    Well, don't know who this specialist is, but they have no idea what they're talking about.
    Pull and send me the PC-V map. While it is a dynamic system, it does need touch ups by me at every service or annually.

    OK...I admit it. I am a luddite when it comes to computers maps loading and downloading...Todd, do you have a tutorial somewhere on the site for the computer illiterate, or know where one is so I can send you my map for an update...which I have never done.
