Not sure about that, the Euro standard is even more strict then California emmisions laws.

And no, mind hasn't got anything thing there either.

Oh, you can be be sure about that awright....

If the dealer removed part of the emissions system as installed by the manufacturer....that's definitely a no-no.
Now if BMW removed the CCP at the factory, as it seems may be happening, they are obviously confident the bike still meets the requirements/specs as it was originally approved for import to the USA, or have gotten it re-approved....

I have another possibility why all the `04 bikes do not have the CCP installed (since new).

BMW introduces the dual spark engine and it STILL surges (with the CCP in place). They remove it and test the bike without the CCP and find the emissions are OK and it doesn't surge. The CatBox fire stays lit and all is well.

My local dealer removed them upon assembly, I questioned it once, caused the bike to run a tad leaner, probaly contributed to a small amount of surging, on the plus side it added a mpg or 2.

Interesting thread, I have the older '02 single spark model and the catalytic converter was removed and replaced with a y-pipe before I owned the bike. Still has the CCP yellow plug in place and yes, the bike does surge at lower throttle openings. I presume the plug can also be removed with the single spark models? If so I'll let you know what improvment I get.

I am curious to know if no CCP means open-loop only. By that, I mean that the O2 sensor is not used. I think that one should be able verify whether the sensor is being used by measuring the voltage of the O2 sensor (about 0.5V when in closed loop, near zero when richer), but I have never seen it done. Can anybody suggest a way to check if the system is running in open-loop?

There is a great deal of confusion regarding the CCP. Actually the ECM in our bikes has several, burnt in, fuel maps and the different color CCP selects one of many. If you have a CCP, very carefully, pry the cap and you will see that it is a simple short between two of the posts. I no longer have mine and honestly don't remember what two pins were jumped.

Irregardless of the single plug, or the two plug configuration some of our bikes are prone to surging.....i.e. too lean of a mixture when the O2 sensor is in the loop (closed loop), usually during staeady state cruising. Unfortunately this is the result of a simplistic control system with a narrow range (read; cheap) O2 sensor.

In answer to your question the only accurate way to see the operation of the O2 sensor is with an oscilloscope, measuring the output voltage. The problem lies in that the voltage signal is reading continuously and it will be impossible to see a response from a DVM. Actually the ECM does take about a 1 second average of the signal to adjust the A/F ratio.

In closing, you will be surprised of the compromises that have to be made during the engineering stages in regards to cost, reliability, environmental regs and profit margin.....need I say more. BTW, I do have a scope, but never drummed the interest, because short of replacing the ECM or installing an aftermarket unit there is little that can be done.

Of course there is the option of changing the pressure regulator from the stock 3 Bar to that of the earlier generation K bike which is a 3.5 Bar and then there is a difference.....but I digress and besides is way too much of a pain for most.

This CCP fact creates opportunity. We've all read about the rider-selectable mapping available on several new bikes (GSXRs, B-King come to mind) which allow on-the-fly change of tuning to suit riding conditions or preferences. Perhaps the CCP "switch" could be accessed to do similar mapping changes for the R1150R.... not that there's much performance promise for the boxer via tricky fuel & spark tuning (e.g. Dynojet PowerCommander style), but a bit of tweaking might be useful.

In Buell circles these days, the use of the ECMspy to tweak mapping is in full bloom. Not sure how accessible our Bosch (?) ECU is to outside tampering, but if someone can produce a "performance chip" option like the Rhinewest, then why not multiple maps with ability to choose while riding?

Thoughts?

The different fueling/ignition "maps" BMW has programed into the Motronic are intended to adapt it for use on different OilHead motors that have different cams and compression ratios. Utilizing the full capabilities of the Motronic's computer is excellent thinking, using the "modular concept" to reduce parts inventory costs. Here's everything I saved about the CCP's:

CatCodePlugs:
--Yellow: R1200c, R1100s, R1150r, R1150gs, R1100rs, R1100rt P/N 8 366 282 (jumps 30/87 pins together) = USA and Australian map

--Pink: R1150rs, R1150rt, R1100r, R1100gs, P/N 8 366 625, Jumps 30/87/87A (Pink or olive green CCP = RS/RT maps).

--Grey = "Bad Fuel" CCP (comes with GS Adventure) (No pin jump data)

--Brown CCP jumps the 86/87 pins together (No model data).

--The 87 pin is the common pin for all CCPs. Removing CCP gives the "EURO" map. There may also be an unused R1100S map on the chip as well.


I say you can make your own "jumper wire setup" to try these other maps -but- you may find they aren't any better than what you have -unless- you have no CCP installed. In that case, depending on you bike model, you will/may see an increase in trip fuel economy if you connect the 30/87 pins (USA map) together. You can also get creative by connecting the common 87 pin to 1 or 2 of the other pins and see what happens to driveability, power and fuel economy. Remember to use "the procedure" to reset the Motronic memory between map changes.
