Cat code plug bridging????

I may be wrong but I "think" the motronic on the R11S is also 2.4 and that they use the same setup etc

My reserve light comes on when the tank is full.... I think i'll wait for someone else to try this first though

I wonder if your's has somehow shorted with a full tank

No CCP lambda unplugged Bike ran great

I think that you will find that if you just unplug the O2 sensor, then the ecu registers the fact that there is a 'fault' in the system and goes onto a default map. So by just unplugging the sensor, you are not actually doing what you think you are doing!

If you want to run the bike in the standard configuration but without the O2 sensor, then you need to replace the sensor with a blanking plug but leave the sensor connected but taped up to the frame or something. You could also get a little black box that connects into the circuit instead of the sensor that fools the ecu into thinking that the circuit is complete and the mixture is perfect! The ones that I used to use and sell are not available anymore

Back in the day, my BCR ran best with the CCP removed and the O2 sensor replaced by a blanking plug but still connected!!

The early Techlusion unit I have recommends the O2 sensor be disconnected not at the exhaust end but at the, err, other end, which I have. Removes the need for a blanking plug, obviously, but I don't know any other reasons for it. Bike seems to run well though.

I was told the lambda only really comes into play around tickover speeds anyway?

Fixed throttle it definatly has an affect on mine

Most of the 1100s are pushing 10 years old now so we have ten years or more of other peoples bodges to sort out mine has had 7 previous owners so who knows what has been done in the past.
i think this reflects in the way one setting will work on one bike and not another

I would have thought that leaving the lambda sensor conected but out of pipe would have sent a weak signal at all times but i bow to your knowledge on the subject
i wish we had points and carbs instead of all this newfangled stuff

[slparry]

I may be wrong but I think leaving it disconnect means the "safety" setting which is a bit rich. Which given I have a full remus probably helps mine

[Dai wiskers]

Pulling the CCP with the lambda conected in mine it seemed to be very rich when warm it rattled like it was about to go bang i think it was washing the bores also on the overrun it was igniting fuel in the pipes
All i did to get yesterdays results was disconect the lambda sensor under the tank without replacing the CCP i think this has taken the closed loop out of the system so it now runs soly[SPELNN] on open loop setting

Since time immemorial, it worked below 3000 rpm and/or up to one third throttle. However as time has gone on the EU requirements (among others!) has meant that more and more of the throttle and rev. ranges are attempting to be controlled by the O2 sensor circuitry.

Modern bikes (and cars) are pretty much all the time now.

I would suspect that there is something else going on there. My BCR did not have any of those issues with the CCP removed, O2 sensor removed and blanking plug fitted as well as the K1200RS/R1200GS fuel pressure gizmo fitted. Can't have been much wrong with it, because along with the exhaust mod and changes (Laser with chip) it gave a dyno reading of 102.4 bhp at the wheel.

Fact - if you disconnect the O2 sensor electrically, it changes the behaviour of the ecu!!

I have just had the universal four wire lambda sensor through the door yesterday so will try conecting it and tuck it out the way somewhere

[Dai wiskers]

The sort of outcome well at 139 miles the light came on and stayed on it was on and off from 131 so that i am happy with never seen more than 120 and thats been running in

the other thing as to what spec the bike is in i still don't know it ran up through 8500 still pulling no rev limiter cutting in asked my mate that i had the bike from if the previous owner had mentioned if it had been chipped "no idea" was the reply!

No CCP and lambda disconected definatly not get you home fuel map will posibly have to retard the ignition a touch on one start it fluffed through the inlet

[SAS Tom]

Do you have a link to the lambda you bought?

[SAS Tom]

Has the bike been consistently more economical since you fitted the new lambda?

[Dai wiskers]

This is the one i bought but have not fitted i may at a later date to see what difference it makes
http://www.ebay.co.uk/itm/140630407170? ... 1497.l2649

My bike is running fine with the original one in the pipe but disconected under the tank and the CCP removed

Last count was 139 before the light came on and stayed on

as i have said i don't know what chip if any is fitted but no techlusion or PC but it will pull through 8500 easy and still pulling strong the standard rev limiter cuts in at 8200 from what i can make out

It has the accelerator cable fuel spoofer fitted, also val singleton filter, air box top has had the restrictions removed and i have now fitted my fibreglass snorkle [the new inside is bigger than flexipipe outer] also y.piece, rocket sprockets, throttle bodies rebuilt with kit's from cata dan TPS set to 385 valve clearences are set at 8 in 14 out thou, endfloat on cams set to the thinnest gauge i had not sure what these are in metric

Yesterday i filled up with super unleaded and it does seem to run smoother but at 1.49 a litre i'm not sure if this will be it's future diet
The decrease in fuel consumption could be down to the rocket sprockets as well as some of the other mods, the bike will pull from 2000 revs in top two up on a flat road with very little complaint and will pull strong from just under 3000 on just about any road hold on tight at 4000

The way the bike is now i'm keeping it this way i just can't see any reason to try anything else [well ok i have just pinched the nozzle from an old fire extingusher[spelling] to try to make a new/extend the intake funnel fitted]

Have fun out there and try disconecting the lambda probe under the tank and pulling the CCP before spending more on a new lambda sensor

[Daveg2812]

I'll have to try mine without the CC plug. It has a different one fitted than standard, yellow I think, but that was before I fitted the Techlusion, removed the lambda under the tank and recently fitted the sprockets. On Saturday I went out for a run of mixed riding, some fast but a lot of steady stuff, and the fuel light came on at 113 from a brimmed tank.
