Remus and Y piece

[sproggy]

If you were going for programmable ignition then you could keep an injection setup (not necesarily the standard one) and use the same unit to run that. The improvement in controllability should allow a better result than using carbs, shouldn't it?

Adjusting the signal from the temperature sensor is an interesting way to affect the mixture - does it allow a fine adjustment or does it just switch between a 'rich map' and a 'normal map'?

I wonder if it's possible to get hold of an application list/description of all the factory maps and the CCP jumper settings that access them? Somebody somewhere should know...

Agreed an injection set-up would provide better control,but the gain over a carburettor conversion on an engine of this relatively low state of tune isn't worth it.
For CCP applications, all the info is in each countries parts book,you're gonna need a lot of time to source it all.
Best bet,link wires and a dyno.

We've been after this for a while and also an explanation as to why some bikes leave the factory with a CCP and some don't. I'm also wondering what the differences are between my early year 2000 model motronic and the later 2000 models. They must have changed it for a reason?!

Does anyone know anyone who has taken the plunge and fitted the newly available power commander and how much they paid? These things seem to be the only way to get your bike finely tuned with regard to fuelling.

On another note has anyone ever had their bike dyno'd with a y-piece and can and no chip or techlusion and been told that their bike isn't running lean somewhere in the rev range? All the folks who say their bikes are ok seem to base this on the number of trouble free miles they have covered or because their dealer told them it would be fine......not on a dyno test.

Fatal, keep us posted with the dyno result of steptoes link - it's a pity you haven't got a remus end can to try it with as well.

Steptoe, 'You can always adjust the mixture with the CO pot...'

If you're talking about mid-range adjustment,did you put this in to test our knowledge of how everything works?

just for the 1100 - works the same as the K series 1100 - only setting it up at idle- which will then remain constant throughout the rev range - nice and crude, same set up and diagnostics as my porsche

Steptoe,the chap I got all the info about how everything works from reckons the Motronic has the same 'computing' capability as a 70's LCD watch.....!
What're you calling crude?

Casio are now doing a ccp link -

I've been asked about this a few times and on the back of that, have asked BMW what the official line is on it so here goes:

The Remus Y piece and Revolution end can are the same item supplied by BMW under the A C Schnitzer name (not being a complete geek I don't have the BM part numbers to hand, only Stella ). Should someone purchase the Y piece and can from a BMW dealer it will not invalidate their warranty provided it has been fitted correctly either by the customer, a grown up or a dealer. Gaps at the joins you could filter a goldwing through do not come under the heading of correctly fitted.

The person I spoke to did not elaborate as to whether a Remus Y piece and can not bought through BMW is subject to the same allowances but given they are the exact same product with a different part number, I'm sure it wouldn't take a court of law to press the point home. This is my assumption but I don't feel it is inappropriate to mention it at this point.

The ccp issue isn't so cut and dried as the fueling tolerances should be sufficient to allow for the variances involved.

However .... not quite a but, but close! As has been pointed out by many already in this thread, different bikes run to different tolerances from the factory - if a bike is found to be running lean then a ccp is fitted. Most do not seem to need this, a small percentage do and a lot find it beneficial if not essential.

Even on the standard set up of Cat and factory can, some bikes require adjusting to the fueling which is where the elusive yellow relay (282) comes into it ... it addresses certain fueling issues on a small minority of bikes and is fitted FOC under warranty when required.

oooof ! All this technicality (well it is the technical forum). When you get so many different answers to a question, I reckon that no-one really knows the answer, including BMW.
Just hope I keep on being lucky.

It was my understanding that when the CCP (if fitted) is removed, the motronic reverts to a richer fuel setting. Almost a full proof emergency get you home setting. I don't believe it is as crude as this but I think the principle is correct. I haven't heard the above case before where a CCP is fitted to lean bikes.

My bike is back to standard now with cat and original end can. No CCP is fitted and never has been. I have it in my mind that my bike is pretty lean anyway, hence no CCP and when I fitted the Y-piece and end can the motronic simply couldn't cope. I can assure you that the y-piece and end can were fitted correctly and I didn't even experience any popping as all joints were soundly sealed.

There can't be anything else wrong with my bike as it did 20k before I fiddled with the exhaust and has done 15K since reverting back to standard and she's running well every day of the year. It was the 2000 miles with the remus that holed my piston so there is definitely a problem with fitting a remus system on my bike and leaving the motronic to compensate without influence. Adding a yellow CCP certainly wasn't advisable when I modified the bike, the advice was more along the lines of, if you have one - bin it!

I'm tempted to go for a few more dyno tests to try all sorts of motronic jumper combinations with and without the cat and can but I'm thinking about changing my bike and as all GS's seem to be completely different I don't want to have to repeat the exercise with a newer bike! Yes, I am going to buy another GS, there's no bike on the planet that can do what I ask of it any better! The holed piston was my fault, I should have dyno'd her immediately after fitting the exhaust system and I could then have bought a chip or techlusion. Instead I spent over £200 fixing her up and ended up back where I started.....with a cat and standard can!

Words cannot convey..... well they probably could

Well I rest my case, last weekend I tried in vain to fit this damned system, and couldn't as I didn't really have the tools, and most certainly didn't have the CPP, so I callled BMW and they said they would supply the CPP (a white one), so off I went yesterday to pick it all up form a very nice young lady, who was very knowledgable about the whole thing, and said basically that as mentioned before, if it is all fitted correctly then there will be no damage, and I'm even getting a letter to confirm that!
BUT today I have tried again (with lots of tools, copious amounnts of WD40, some blood, and lots of sweat) and I can't fit the ferking thing! ARGRGRGGRGGRGRGRGRG!

So I'm afraid I give up... that's it it's off to BMW, and they can do it. PANTS!

First I got the lower bolt off holding the can on, but then couldn't get the bracket to come loose, so I figured, maybe I can wiggle it free, so I undid the top bolt, but no, wouldn't budge, well I thought, being a positive chap, I've got to replace the Y-piece as well, so I'll just undo the whole lot, and remove it all tuti quanti.
Cunning huh! the 2 font bolts came free relatively easy, now just the center stand thingey.... BO**OCKS.... the left side stupid six sided (sechskant in German, dunno what it's flipping called in English, and frankly my dear I don't give a damn!) sheared..... great... so do I now hacksaw it, hammer it, plead with it.
I mean c'mon, this is supposed to be a go anywhere do anything bike, as I've said before, what happens if you fancy changing your exhaust system while travelling through Outer mongolia or some other far flung place like... East London, stuffed I am, and well hacked off.

Anyway... just thought I'd let you all know, now you can take the P*ss.

Had my bike dyno tested this morning (06/06/05), having fitted the 'steptoe link' the difference was hardly noticeable. Power was very slightly down by approx 0.5hp and 1ftlb, the fuelling at the top end of the throttle range was as before, ie; pretty much spot on, and the lower throttle opening was still a bit lean, but I was told nothing to worry about. So I'm going to leave as is, I'm not forking out a few hundred quid for a power commander, not unless I fit something like a remus can, but then I'll see what the dyno says first. I hope this helps. Fatal.

Then you deserve all you get for not preparing for the trip properly before you left

 

[Comfy Old Boots]

Actually, I gather that hese can be a real swine to fit as nothing lines up 'just right'. The BMW tech that did mine was in for a fair amount of heaving, hammering and swearing, and he told me that mine was far from being the worst he'd ever fitted.

Why it shouldn't all be manufactured to the same spec I don't know. I thought they'd be a simple bolt-on job .....

Oh, and the sevice manager at my local dealer told me that I didn't need to add any relays or things like that. As long as the lambda probe (?) was properly installed everything would be OK.

...bit on from post but how and ever...

I'm on an 850. Thank goodness the lamda probe/sensor isn't in the exhaust . I don't have an 02 sensor on mine. Ok, you caught me out, I don't have a gs, I have an r. Had one of the old massive one piece cat/muffler yokes. I'ts soooo massive I can't describe. The bike feels much better with new remus but it was very simple to install. If your downpipes are healthy all should be ok? Mine just has the downpipes and left foot peg as support. Need a chip but what the hell. I'll enjoy the sound and keep reading.
