    Booster plug

    Has anyone tried one on the new 1250 GS as they now make one .
    The feeling is great already but maybe could be made better as the device riches the mixture on a monitored system , similar to tunning houses making them less lean , but without the ecu remap route.

    I fitted one on my Africa Twin and if I’m honest couldn’t really tell a difference in performance, only fuel economy which was slightly worse, about 25 or so miles less per tank. Doesn’t sound a lot but noticeable nevertheless. Other people have said they have made big differences though so you decide. Cheers

    Honestly, as long as you have your stock O2 sensors connected it won’t do a thing. Although it will shift the intake air temperature, the ECU will figure out there’s a fueling error and fix it in short order. The end result: no change to fueling.

    I’ve got one from my 2012 cam head that I don’t use any more, as the bike has been sold. I now have a 2015 GSW fitted with a AF-Xied. So if anyone wants the booster plug free, just PM me your address, and I’ll post it on.

    A small donation to cancer research or similar would be nice......

    I had one on my Tiger 1050 and it worked as advertised to smooth out low speed snatchiness without any adverse side effects. Having said that, my 1250’s fuelling is as smooth as butter so I personally don’t feel the need for tweaks of any kind.

    Would you not think tho that the plug monitors , adjusts the mixture so the ecu would not re adjust as the readings are normal but more constant and within the parameters of the fueling map , just tweeked a bit to run richer.

    Booster plug and hilltop map work same, bike is good the ECU fixes fuel and all is gone, and you see nothing, better wait for afxied maybe soon on market.

    Stick, Buy a BP if you like, I have one sitting in my junk drawer. I’ve carefully measured it, with a Wideband O2. The BoosterPlug works for minutes and then its effect is gone. Here’s the shortest explanation of why that I’ve posted previously:

    When you install the boosterplug, it changes the temperature signal sent from the intake manifold to the ECU (Motronic or BMSX). Momentarily, that results in the ECU seeing a cooler air temperature and adding about 6% fuel. However, moments after that, the ECU is reading the O2 sensor, sees that the mixture is too rich and within seconds reduces the fueling to exactly where it had been before the addition of the BoosterPlug (let's not just pick on them, every IAT shifter has this problem). And worse, after enough riding, all the long term trims have fully adjust to the IAT temperature shift and there is no fueling difference anywhere--the long term trims are all set to about 0.94, which is 6% less than 1.00. So the simple math is that the BoosterPlug says to add 6% to fueling and the Long Term Trims say to remove 6% fueling and you end up back at stock fueling.

    Fitted one on my T10 smoothed out bottom end in sport mode and increased pick up in touring mode. Peased with result for little money and done in your own garage.

    Can you send some written info or can I use your post as reference , as I could then make a claim against them for selling a product that does not work , would you believe it a company selling a product ( US Company ) world wide that a scam that does not work.
    I have however fitted one to my KTM and it runs better , used more fuel , so I would think on that bike it does work all day and does not ,as you say, revert back to the original map. I will try one and see how I get on as I will notice any changes as I did with the HT I had done on other bikes .
    Sometimes a simple idea works.

    How is it a scam if it works. The fact the gs has moved on technology wise to compensate doesn’t mean it won’t work ( to a minor degree) on other bikes. At least it’s a genuine product you can hold in your hand and not a “map” transmitted via voodoo spells to an inert box.

    Too subtle for me. You need to be a lot more obvious than that
