    Forgot to say error 4 long flashes 5 short is for 02 sensor, as a first step I can send you the test procedure on how to test the 02 controller if you have a multimeter.

    Never had one of my 02 controller fail since selling the for the past 5 years have a few thousand units out there, the 02 sensor circuit has no connection to the bikes horn can not see how it can sound the bikes horn, can you refit the mod to confirm or post it back to me for testing.

    Thought you bought a 790. I need your email address to send an invoice, do you want a fuel + 02 controller or just an 02 controller, PM me the details.

    I have had a few guys asking where can they get my 690 mods. https://www.ebay.com.au/sch/7416kevxtx/m.html?item=143315034961&hash=item215e3de351%3Ag%3AWTQAAOSwRKhdGcJ1&siteoverride=15&rt=nc&_trksid=p2047675.l2562

    The 690 does not need much AFR adjustment with my adjustable fuel mod, 1 to 2 O clock will be close.

    The O2 controller is the main device I would recommend, I can post both mods together to save on postage + you can have a controller for $110 instead of the eBay price of $120, just let me know what you would like to do.

    The Booster plug will correct the AFR in the open loop that is the part of the mapping under acceleration quick throttle openings, my O2 controller corrects the AFR in the closed loop that is the part of the mapping at part or small throttle openings & when cruising. Both mods should work fine...

    Jeff 2016 to 2018 Dukes all use the same part number engine ECU so there should be no reason why it would not work on the 2018 models, you are the first person that I know of with a 2018 model, the O2 controller has been tested on all year models except the 2018 models & don't see any reason why...
