Re: BMW AF-XIED O2 Sensor Manipulators available at Beemerboneyard.com !!
Got the first one of the two I got from you installed on the SOs R1100S, 04 model.
This has got to be the most cost effective improvement to performance I've ever seen- and I've seen a bunch over almost 50 years of tinkering with performance mods plus my track time with my own and others toys. For street use, the idea of maintaining all of that very expensively developed factory programming but tweaking it electronically to what is really needed is the only way to fly- no need for doing your own maps, hacking into factory wiring (for those who don't know, these are simple plug and play or require only minimal connections)
The AF-XiED completely eliminated all the low end nastiness of BMWs stock fueling and provides a much wider and more linear powerband. This thing will surely tempt you to wear out tires faster because the bike is a lot more fun with it installed. With it in place, 6th gear full throttle roll ons from 60-90 comparing her R1100S and my currently stock (but not for much longer) RT came out so close to dead even that the difference is both hard to detect and of no significance. Of course the RT is more powerful but it is heavier plus carrying my extra weight compared to hers and it punches a bigger hole in the air- but there no way it could leave her bike behind at any sane public road speeds.
Hope folks have the sense to try one for themselves and that you guys sell a boatload of them. It really is as good as noted by folks in the web threads and as you also note.
Have one from Roger that goes on another bike this coming weekend for some data logging, etc
