    Install one of the cables properly at the O2 connector and battery negative. Before plugging in the AF-XIED, start the bike and measure at the red wire for 14V.

    Shut off the bike and plug in the AF-XIED (And RAM if needed). Start the bike and confirm the flash count. On “F” revision modules the count happens sooner than on “G” rev modules. On an R1200, wait for one minute and then measure the voltage on the blue wire. It should vary between 0.2 and 0.8 volts.

    On an R1100 or R1150, you have to warm the bike up to 4 bars on the RID before measuring the blue wire (O2 control) voltage.

    Can someone point me to some pictures of where to splice into the O2 sensor on the 1150 gs? I get the theory from the instruction sheet, but would like to see where others have actually performed the installation if possible. My searches are coming up short. Happy Thanksgiving!

    I haven’t seen a photo but when you have it apart and need help, just ask. When you get the tank off and separate the O2 connector (temporarily) it will be straight-forward based on the instructions.

    And while you’re doing it, it would be great if you could add photos.

    Hey thanks so much Yuza! Is that middle pic the finished product? That one positap connector that installs at 90 degrees looks like a pain to make tidy.

    Yes middle picture is the final result, all wires isolated with tape and secured to frame by zip ties
    No worries, it is super easy with posi tap, entire process took me 30min max

    Yuza,
    Did you see the change note about adding a ground wire to the O2 sensor GRAY wire? It looks like you don’t have one.

    Pics are few months old, I have added the extra ground wire later

    Simple. But I have no idea how I’m gonna make it look nice and neat like Yuza did lol. That’s for tomorrow...

    How much do those stupid O2 sensor connectors cost anyway?

    Roger why does that gray wire just get left unconnected from the ECM?

    The purpose of the gray wire coming from the Motronic is to provide a ground to the O2 sensor. However it is not a ground that can be used by the AF-XIED, which needs a stronger ground. Since the AF-XIED is grounded to battery negative, so is the O2 sensor. The AF-XIED now provides the ground via the yellow black wire because the AF-XIED and O2 sensor must use the same ground.

    Thanks Roger, you satisfied the curiosity of my 8 year old. That’s tough to do!

    I cleaned up the AF Xied wiring tonight to complete the install. I disconnected and trimmed the adapter wires to line up better once reconnected.

    I used a combination of shrink tube, split loom and electrical tape to protect it once configured to my liking.

    All set! Tank is back on with all new internals. Can’t wait to ride it!

    My battery had been disconnected for a week or two (was working on fuel tank also). When I first connected battery I turned the key on and off once or twice (making sure fuel pump primed). Either the second or third time I did the throttle relearn. Does it have to be done immediately when first turning key on? Or should I pull the fuse and do it again?

    I want to help as friend install the AF-XIED on his 2019 K1600GT. Can anyone give me pointers on how to locate and access the O2 connectors. I’ve got a learning curve to go through in this bike!

    Wish I could help Roger! I pulled my #5 fuse to reset the motronic. Noticed I don’t Appear to have a cat code plug. Should I? Bike is totally stock aside from 1200 injectors and now the AF Xied.

    Roger,

    Thanks very much for your experience, testing, and insights surrounding the haunting stock surge issues. I have a 2016 R1200 GSA-LC and the classic symptoms are sadly profound. I've been combing the threads on this and would appreciate confirmation that the following combined solution is tried and true:

    + Booster Plug
    + AF-XIED

    I already have a Booster Plug onboard (only a partial solution) and your thermostat analogy was very clear indicating the O2 sensor shift is also needed, attainable through the AF-XIED. Before I read this I had intended on removing the Booster Plug and had ordered a PC-V which has not yet arrived. In subsequently reading your comments on the benefits of retaining O2 sensors and associated BMSK functionality, I decided to also order the AF-XIED units for my machine as a preferred alternative thereby leaving my BPs installed (and possibly bagging the PC-V).

    Couple questions:
    1) With BP and AF-XIED, what setting should I start with (or "set-it and leave-it")? If this is a matter of preference, please recommend the shweeeet-spot.
    2) Is it possible to utilize all devices (BP, AF-XIED, and PC-V with bike-specific maps) and derive increased reliable smooth power from idle on up, or would this confusalate the whole shabang?
    Note: I have a K&N air filter and alternate between stock can and Akrapovic slip-on (CAT retained throughout).

    Thank you Sir!

    I’m surprised that you find serious surging on a 2016 GSA. My 2017 RT is fueled very well with no real surging, but it does significantly benefit from an AF-XIED in throttle response in the low to mid range. How long have you felt the surging and how would you describe the symptoms?

    A BoosterPlug does nothing at all for your bike if the O2 sensors are connected, and I don’t recommend removing them. Take the BP off and sell it.

    An AF-XIED will add fuel and may resolve your surging problem but we’d need to hear more about what you’re experiencing and when it started.

    A PCV requires that you disconnect the O2 sensors and is much harder to get set up correctly. If you also purchase autotune, and you are sharp on fueling and good with technology you can get it set up correctly but you still end up with your ECU not having all the info it was designed to process.

    The AF-XIED and PCV are either/or. You use one or the other, not both.

    The sweet spot on AF-XIED is 7 or 8, start with 7.
