    Nice install FSAddict! I think your decision to run at setting 7 (about 14.1:1 or lambda 0.96) is only 4% more fuel added to the mixture ... and yet it transforms the bike. Many of us started at 4% and then tried higher. It will be interesting to see what works best for you.

    Credit for this goes to Steve Mullen at Nightrider too. The AF-XIED is his base design. Good guy, good businessman. He's just kicked off a larger run of devices.

    Just ordered mine. I'm always tinkering with ways to make my GS run more smoothly. So I'll try this and see how it goes. :thumb

    Nightrider.com and Beemer Boneyard will soon announce production and regular availability for the BMW-AF-XIED in-line enrichment device. This simple device works with the power of the Motronic or BMS-K to accurately richen the Closed Loop fueling of BMW motorcycles. Open Loop fueling is also richened through the regular process of Adaptation.

    (If you already have a BoosterPlug, IICE Air or boosted fuel-pressure regulator, the BMW-AF-XIED works seamlessly with those products and does not lead to a double-enrichment of fueling.)

    You can read about the theory behind using the Oxygen sensor to work with the Motronic and BMSK, my Wideband O2 Project in these places:

    Support
    Primary support for the BMW-AF-XIED will be through this vendor forum. We have a good community of experts on BMW motorcycles here at ADVrider so as the base of installations build, so should the base of knowledge in this thread.

    About 10 of the first production run units got shipped to me, so that all could be checked against my LC-1 before shipment and as a final QA on the production process.

    Some were shipped to beta testers who ordered them, some others went to support new F800 and R1200 beta tests.

    That leaves me with two BMW-AF-XIEDs and two Universal Cables. The Universal cables do no come with OEM connectors, but the cost less. To use the universal cable you cut two wires in the O2 Sensor cable, and make four Posilock connections (Posilock not included). It is very straightforward and can always be reversed.

    Since it will be a while before R1100, F800 and R1200 OEM connectors will be available for delivery, I can offer these two units with instructions for how to use the Universal Cable.

    Anyone interested could PM me.

    Yesterday I decided to "recognize the right answer when told" and shifted to setting 8 (lambda .946). More better than 7, nothing drastic but definitely noticeable. Makes the bike even more enjoyable to ride.

    Filled it with gas, did the 100 mile loop of the island and refilled. 39 mpg by the odometer (so probably about 37 in reality). This is as good as I have ever done with this bike, so it does not look like the extra performance is hurting my mileage.


    Aloha, Joe

    I heard from Nightrider and Beemer Boneyard that another batch of Controllers and R1150 cables will be available soon. R1200 cables are now in the design/check pipeline and should be available soon.

    R1100 connectors are a little further behind but a Universal Cable is offered. Below is a picture of how 3 of the 5 wires in the harness get connected to a stock O2 sensor in the absence of OEM Cables.

    It's pretty easy really. Four inches from the O2 Sensor Connector, cut the black wire crimp splice to each end of the black and tap connect to one of the white wires. One cut, three connections.

    The BMW-AF-XIED has a stock mode so you can return to stock without touching the cable.

    Here's an update, a very similar approach would work for the F800GS using the Universal Cable for anyone who wanted to get a jump on things.

    Thanks for posting that Roger. Looks like we should have the units available approx August 15th. We will have 25 of the main units and cables for the 1150 bikes as well as universal cables. R1100 and R1200 cables will follow shortly after.
    Thanks!

    I would be interested in the 1200 version, and test it against the Rapidbike 3 I am using now....

    How can I get one?

    Thx,

    If you contact Beemer Boneyard or Nightrider.com they will let you know the schedule for the R1200 OEM cable. A source for the connectors has been found and is being qualified now.

    It would also be possible to use the universal cable but the OEM connectors will be easier and are nearly there.

    Here's an idea of how gas mileage is working out at lambda 0.94 (6% rich AFR). Put 143 miles on my bike the other day. Here are the stats.

    147 miles odometer, 143 miles (google maps) (odometer error 3%)
    90 miles highway (60-75 mph) est. 68 mph average
    53 miles local/stop&go, speed less than 50 mph
    Top case and two side cases, windshield full up
    Air Temp 75F

    2.877 gallons between fills (error allowance +0.1 gallons), 143.2 miles,

    average 143.2/2.877 = 49.8 mpg (with error allowance 143.2/2.977=48.1 mpg)

    Next Up: A test run of lambda 1.08 (AFR 15.9:1) 8% leaner than stock

    For those who are interested in adding BMW-AF-XIEDs to R1200 or F800, the OEM connectors have been qualified and will be available in the coming weeks. Contact Mike at Beemerboneyard or Steve at Nightrider for availability.

    Running the Oilhead Very Lean

    The Innovate Motorsports LC-1 has two analog channels. One is usually used to simulate a Narrowband O2 output. The other analog channel is usually set to drive an AFR gauge, however it is possible to program it to simulate a Narrowband O2 output as well.

    With that in mind Analog 1 to lambda = 0.93 (7% rich, 13.65:1 AFR) and Analog 2 to lambda = 1.08 (8% lean, 15.9:1 AFR). By means of a selector switch you can choose which mixture the Motronic is using, even while running down the road.

    You can see in the chart below how easily the Motronic moves from Closed Loop at 7% rich to Closed Loop at 8% lean, and also how well it holds Closed Loop at either setting. Also on the chart is a reference line at 14.7:1 which represents the stock oxygen sensor setting.

    [​IMG]

    I had a chance today to make a 50 mile run with Closed Loop at the very lean setting of lambda = 1.08. Some observations:

    --The Motronic easily adjusts to 1.08. This wasn't a very long test but under riding conditions over the 50 miles the bike seemed to be running normally, but with, for lack of a better phrase, a more anemic feeling.

    --In cruise mode at speeds up to 60 MPH (top speed I could run for any distance on the roadway), there was no misfiring and no pinging. In fact I tried to make it ping with some uphill roll-ons and couldn't. The engine didn't seem to run any hotter than usual.

    --Since my BBSs were set to idle at 13.65:1, I had to keep the fast idle lever up to idle at 1100 RPM. With the leaner mixture it takes more air to idle at a given speed.

    --The engine performed "okay" but it took more throttle to start off than in the richer setting, the bike stalled as I let out the clutch to leave the driveway. Roll-on throttle while cruising, led to a very slight hesitation before acceleration

    --At low speeds, throttle input exhibited some jerkiness during transitions from acceleration to deceleration that aren't there at all at lambda 0.93. The "hop" that can occur when the bike comes out of Overrun Fuel Cutoff was pronounced.

    --The natural up-shifting point seemed about 1000 RPM higher than I grown accustomed to with richer than stock mixtures. It really did not want to be upshifted until 4000-5000 RPM. It just wasn't settled and ready to be shifted much earlier.

    --Was there any surging? Yes, but only a bit and no more than I remember with a stock O2 sensor. Mostly light throttle in the range of 3000 to 4000 RPM.

    --The course was 5 miles long with short stops and starts during course reversal. The 53.5 miles on odometer (51.9 corrected) was ridden mostly at speeds between 45 and 55 mph but top speeds were 65-70. Fuel consumed was 1.05 gallons +/- 5% which is about 49 mpg +/- 2 mpg.

    Summary
    In effect, this test was a side by side comparison of a richer fueled R1150RT and a leaner fueled bike. There's not question which is the more satisfying motorcycle to ride, the richer mixture by far.

    Although the Motronic seems very flexible and able to run rich or lean of the stock setting with modified Lambda input, there is a big difference in the feeling of the engine. Richer mixtures (plus 4-6%) lead to a much smoother, slightly more powerful engine, especially below 4000 RPM, that "asks" to be shifted about 1000 RPM lower than a leaner one.

    Leaner mixtures (minus 0-8%) lead to a more anemic feeling and seem to amplify whatever bad manners the engine exhibits (OFC hop, surge, roughness, hesitation). Overall it was an unpleasant ride.

    By the end of the 50 mile test I was very happy to flip the switch back to lambda 0.94 where it's going to stay for the rest of the summer.
