AF-XIED for 1150gs fitted and first tests.

[cbrgaz]

I tried one of John's chips in my bike and it didn't work well for me (I'm an isolated occurrence by the sounds of it). So I decided to stump up for the AF-XIED unit in a effort to resolve the surging I was suffering......... It fixed it and I'm happy.
I guess it depends what you want to spend or gain or resolve I guess.

Cbrgaz, keep up the report. I'm just damn confused about all the info...

I shall indeed. The bike in my opinion runs the best it ever has, no increase in fuel consumption, no surging so i'm a happy camper. I use 8 flashes as i found the 7 flash setting made for a little surging after a few hundred miles.

I have run a pair of XIED`s on my 09 1200gs for 15K miles having moved on from Power commander 5, etc.
My findings are that on my bike they run a little richer than the literature settings.
I have a full Remus exhaust system. ( no balance pipe ) with extra lambda sensor bosses close to the stock ones.
My data logging is done via a 2 channel Innovate LM2 for the AFR and I have spliced in an 0BD2 socket ( the R1200 uses ISO 14230, KWP2000 Protocol for diagnostics) Whilst this does not give as much info as the GS911 it is sufficient for AFR data logging.
I can record hours of road data and play it back on Logworks , Air fuel ratio ( both cylinders) versus Throttle position, RPM, Road Speed, Engine load, and Closed / Open loop status.
Whilst the XIED has its limitations I have found it to be far better than the other options.
I have found setting 6 to be 13.8 which I use when touring 2 up and setting 7 to be 13.1 at which it runs a little stronger but uses a touch more fuel.
These are the findings on my bike. They are very easy to fit and set. These are keepers.

Hi Mistacat, Thank you for doing all the logging. The data you have supplied is very helpful to everyone with an R1200. The average AFR in cruise while using the AF-XIED is related to the average exhaust temperature where the stock O2 sensor is located. The hotter the exhaust, the lower the lambda value for a given AF-XIED setting. So setting 6 on an R1200, with a specific exhaust could produce the same AFR as setting 7 or 8 on an R1150, if its exhaust is hotter.

I've PM'd you, I would like to have a look at your LM-2 data.

[Mistacat]

Thank you for the explanation regarding exhaust temperatures.
I have emailed an LM-2 Data file to you for setting 6.

How much does the unit cost by the time you have shipped and been stung for import duty?

I'm wondering if there is a bulk buy opportunity. I can get an LC2 for 150 squids, but I am still not clear on the difference between the afxied, techlusion and power commander 111. My bike seems to run fine but there is a definite kick in the power at higher revs. I run a twin spark 1150 no CCP plug (standard) y piece (no cat) and standard end can.

It works out around £145 plus post. If customs get you I would have thought another £30 by the time the post office add their handling charge. I got away with it this time for a change.
My primary aim was to make sure I wasn't running lean with a y piece and remus (baffle removed). It has definately removed any trace of surging, but I did'nt think that affected the twin sparks like yours?
I need to get some more miles in, but its just that bit crisper and manages to pull a gear higher that what I was used to. At the moment I would say the difference is not startling, just a subtle all round improvement. In theory this will improve as well over the next couple of hundred miles. Your set up could well see better results straight away as Rogers bike was a twin spark (an RT though) running, IIRC, a same exhaust set up as you.
If your ever down south you would be welcome to try mine. It takes 20 mins to fit it.

The LC-2 and AF-XIED do the same thing. They shift the fueling reference. Once the reference to the Motronic is shifted, it does all the work of richening the mixture, you retain full functionality of the Motronic and the device only connects to the lambda sensor connector. For the LC-2 you have to do some programming and wiring. And replace the lambda sensor (included in the kit). The AF-XIED is plug 'n play

The power commander III USB with Wideband O2 also shifts lambda (only the PC with Wideband does this) and it also allows you to richen mixture at full throttle. But at $495, twice the price of AF or LC, it's IMO not worth it since the lambda shift richens the high end enough. The lambda shift part does all the work. And you add two connectors to the TPS and two to the right injectors.

The Techlusion disables the lambda sensor (not good) and lengthens the injector pulses. It can be tricky to adjust well because you have to do the work of adjusting the extra fuel in three different ranges and at three more crossover points. IMO it is old-tech.

Here is a report I made the other day on my twin-spark R1150RT. Although I normally run 13.8:1 or lambda equals 0.94 a friend runs 12.9 (12% more fuel) and I wanted to try it. I will stay at 13.8.

Yesterday afternoon I wanted to put Jim's very-rich 12.9:1 to the test on the road. My goal was to find out the lowest RPM before I could make the engine actually "lug". I was amazed.

First off, the bike is fine at 1500-2000 rpm in 5th gear. Roll the throttle, no lugging. Make a left or right 90 degree turn in 4th gear, no sweat. Start in 2nd gear, not a problem, feels like 1st.

Cruise up a shallow incline in 6th gear with no throttle input at 18 mph, 900 rpm (rpm dropped below its usual 1100 at idle), no lugging. However, try and give it some throttle at that point, the engine is not happy--lug, lug, almost stall.

After a little trial and error, as long as the rpm was higher than 1200-1300 rpm, the bike would accelerate without lugging.

With enough fuel the '04 RT engine has real guts.
RB

Edit. In 6th gear, straight and level, it takes 0.7 HP to cruise at 18 mph. Engine torque at the transmission input is about 4 lb.-ft. So add a couple lb.-ft. for my shallow uphill trajectory.

Roger, thanks for posting the above.

One question - have you come accross a case like mine where Im running a weaker '6 led flashes' on the AF-XIED with a Y-piece and Remus without baffle? Although it runs very well, no pinking etc, there is always a niggle that I may be running to lean?

 

[Roger 04 RT]

Mike at BeemerBoneyard runs a setup similar to yours. The greatest risk at low RPMs is that there will be some air reversion back to the O2 sensor from the exhaust outlet. That will result in too rich an AFR as the Motromic tries to overcome the reflected oxygen.

Could some kind soul give me the dimensions of the AF-XIED control box please.

I have very limited space on the top of my Airbox (R1150GS) due to my Intercom/Navigation installation.

I would rather know in advance, before purchasing that I have the room, or have too create more room or reposition things before I venture out and purchase one.

Many Thanks in anticipation.

Ian

Module size is approximately 23 mm wide, 12 mm deep, 65 mm tall.

Thanks Mistacat

That's tiny! It looks a lot bigger than that in the pictures.

Good news, It will fit easily in the space left on top my Airbox.

And a good average AFR across the rev range?

A good place to start is 14.1:1 to 13.8:1. Start with setting 7 on the AF-XIED.

 

[drinu64]

I have John's chip on. AFR was 11.2 on idle. Tps 366mv - no cat or lambda. I set Tps to read 300 and AFR is now 13.2 on idle and ranges from 12.5 to 14 throughout the rev range

 

[drinu64]

Also have a k&n and an aftermarket can

Is this the case after riding a few miles as i was under the impression the TPS tweek doesnt work on the 1150?

 

[drinu64]

Hey blue. I have an 850R.

 

[Deleted account 200123001]

Doh! Ive ordered one for mine now the pinging is getting really annoying.
