    Turning off 02 sensor

    I am fitting a set of 05 headers to my 04 speedy so that I can fit a Competition Werkes muffler that I picked up used for a really good price. I need to disable the 02 sensor as there is no place in the system to install it. Is it simply a matter of plugging in TuneECU and disabling it or do I need to install a tune in which this has been done.

    Someone once told me that there are no stupid questions, just stupid answers. I hope I don't get any stupid answers as I am not confident about being able to tell the difference.

    Great question, I have no answer stupid or otherwise. You lost me on the TuneECU, way beyond my technical knowledge/ability. Hopefully the really cleaver people here will give you the answer you're looking for. So the good price, was it for the shiny or matt black muffler, if that's not a stupid question.

    Dunno about the 04, but on my 06, it was just a matter of unticking (or ticking, forgot exactly which) the O2 box in tune ECU. No new maps and no CEL lights either.

    You can take any tune and just untick the box for the 02 sensor, but you have to save that tune and download it to the bike. So it's like installing a new tune completely, but you can upload the tune that's in your bike and just modify it by that much before downloading it back in.

    Does that make sense?


    So the process would be:

    1) Connect Tune ECU to the bike.
    2) Read the map that's already in the bike.
    3) Uncheck the 02 sensor checkbox under "Devices" on the lower left.
    4) Save the new tune as "JohnsSickTune"
    5) Download (and replace) that tune into your bike.
    6) Eat pie in a world unencumbered with Check Engine Lights.

    Thanks Crash....I can do that. I have never used TuneECU. I have tuneboy and would be able to do it with tuneboy but I have problems with the program I can't resolve and I can't reach Wayne Macdonald to resolve it.

    TuneECU should work fine with your TuneBoy cable. I haven't tried any other cables myself.
