Add on Electronics for Smoother Low Speed Riding

[skylarmav1]

Any thoughts guys? I love the torque of my r1150r but a bit more smooth at low speeds without having to ride the clutch would be nice.

See review below-although not for our bikes exactly-others out there but this one seems to have all of the benefits for a fraction of price. I don't need any deep dive on throttle/ECU/engine management- just do these work and work for a long term?

Looking for insight-Thank you...

No. These intake air temperature black boxes don't work.

Please read the following topics carefully. And for thorough analysis of Motronic oilhead boxer fueling, follow the embedded link to Roger's topic in ADV.

As disclaimer, I've purchased both IICE Aire and Booster Plug. When real experimental results became available, I changed to the XIED.

Thanks Sweat-I will review
Appreciate it

Thanks. Funny thing is I see many of the folks on the sites you recommended felt an improvement in their low speed comfort and smoothness..

The intake air temperature (IAT) boxes have temporary effect: The initial fuel increase in open loop is negated by closed loop adjustment. I defer to Roger for details. Sure, my bike felt smoother following Booster Plug, but the real, lasting improvement required a lambda shift. (Edit: lambda tweaked using AF-XIED)

[skylarmav1]

Ok. So it is temporary.
Fot it. Thanks.

I installed an AX-FIED on my R850R and the improvement in lower speed pulling power and smoothness was dramatic. In fact, the bike seems to have more HP overall. It took 5 minutes to put it on and the factory setting seems to work fine.

Not dirt cheap but it works. It worked from the beginning and some thousands of miles later it is still working exactly as it did when first installed. I'm really satisfied with it.

I also removed the cat converter and replaced with a Y pipe. No doubt that contributed to the noticeable improvement in performance as well. However, looking at the plugs it was clear the bike was running too lean which was specifically corrected by the AX-FIED.

Out of curiosity, is your 1150 single or dual spark?

Also, have you run a tank of fuel with Techron added?

Do you find the bike runs smoother for a couple minutes, before the bike has warmed up?

[skylarmav1]

Hey Rodger-
Single spark with the Autolite plugs (which have virtually eliminated the surge) and while I haven't done Techron I do use SeaFoam every 3-4 tanks fulls.

Thanks,

In addition, the bike runs smoother in the "start mode" with the left handlebar lever in up position. I assume it is because it is getting more fuel.

Now that you mention it-it may run smoother when cold, but after warmed up-if that makes sense.

From what you describe, there are a few things going on.

It runs smoother with the fast idle lever up (if you're talking about riding not just idling) because with the lever in that position your engine never goes into what's called Overrun Fuel Cutoff. The cutoff point is when the throttle is less than 2 degrees Open, and if you're decelerating (even between gears) and the throttle is fully closed, and the RPM is above 1800, then the Motronic literally shuts off the fuel until: a) you open the throttle a bit or b) the RPM drops below 1800. Then the engine kicks back on. An AF-XIED or LC-2 by virtue of running a little richer usually significantly changes this transition for the better.

If the engine is warmed a little but not a lot, it gets extra fuel until the engine reaches about 140F. During the time it is a little warmed up until 140F many Oilseeds run better. This is a sign that something like an LC-2 or AF-XIED will make a noticeable improvement.

The LC-2 is for experimenters like me, the AF-XIED is plug 'n play. Your choice.

FWIW, I installed the Accelerator Module on my 07 K1200 GT, which experienced significant throttle lag at times. There was an immediate dramatic improvement, but a year later, the effect does seem to be abating.

My 02 R1150R (single spark), OTOH, has never surged and otherwise pulls immediately from right off the bottom. I did fit an Akrapovic can, and believe it provided an immediate -- if not overly dramatic -- improvement in low-end torque. Finally, I was experiencing a bit of intermittent "skipping " (for lack of a better descriptive), particularly at steady throttle. I ran one bottle (three tankfuls) of BMW fuel system cleaner (Techron) through the engine, and it has smoothed right out.

[skylarmav1]

Thanks all for your help.

So I ordered the Accelerator Module for one simple reason-economics-it's $45.00. From what I understand it will perform well for a limited period of time which will then give me a sense of whether the improvement will warrant spending $220.0 for the AF-XIED.

I know this isn't the preferred ultimate solution but it is the preferred one in a budget range as a relative newbie learning all I can.

I'll keep you posted!

Thanks a lot for everyone's help...

Unfortunately, the AM doesn't change the fueling but for an extremely short time. How your bike behaves in the first few minutes after cold start is a better test of how it will respond to the added fuel from an AF-XIED.

Make sure you got the Extended version. At least then you can put the temperature probe into the intake manifold. With the simple version you send confusing signals to the Motronic because the AM isn't measuring intake air.

I have three Boosterplugs, you could borrow one if you haven't ordered.

Hmmm....without looking for it, I have long noticed that my roadster feels particularly smooth when I start a ride, but it doesn't feel the same later in the ride. I had always assumed that it was just a subjective perception on my part, rather than a real change in the bike's operation. This is quite a revelation. Looks like there is an AF-XIED in my future.

Here's a cold start log measuring AFR for a single-spark R1150GS. You can see that there is several percent enrichment (about 6% at point 2) until the bike is warm enough to support closed loop operation. I initially came up with the LC-1 (then AF-XIED) because I noticed that even with a BP (which I now know is adapted out) my bike ran better when slightly cold.

[lcarlson]

AF-XIED is on order. I'll post my experience after installation.

[ROXTR]

You'll be very satisfied with the AF-XiED. I run on setting 8 IIRC, nice smooth power from idle to the rev limiter.

[lcarlson]

Just completed my first short ride after installation of the AF-XIED, and I am impressed. I had never had a problem with surging, but with this device the motor's responsiveness and smoothness are significantly enhanced; it just feels "nicer" and more refined (I also had the cam chain tensioner upgraded). I understand that as the Motronic ECU adapts to the new setup over the next couple of tankfuls or so, I may see even further improvement. If so, great.

I had been considering the new 2015 R or RS bikes, but with these upgrades and new Ohlins, no need.

[vwdoctor]

Has anybody (looking in your direction Roger) attempted to play with the oil temperature sensor readings. If you fool the ME into thinking that the engine is cold (or colder) it should provide additional enrichment as well. I understand that I will probably not go into closed loop but the effect should be permanent. I don't think they were too concerned with "engine not reaching operating temperature" as they are now. I might experiment a little. It would be the equivalent of booster plug except if engine never goes into closed loop it should never adapt itself out. Amount of additional fuel could be controlled with the value of the resistance.
It would be "oil temperature shifting"
