I have removed my little yellow box thingy under the seat in the fuse box . I have a 2002 1150R.
What should I expect to happen now.?????????

errrrr, the indicators won't work???

which little box??

That's the 'chip' that tells the ECU what fuel mapping to use. Without it, the Motronic defaults to a base fuel map. Many early users reported that this base fuel map was better than the 'chipped' one. Your gas mileage might decrease, your emissions might increase, surging, if any, might be reduced.

did you reset the montronic? If not, you need to pull the fuse for the montronic computer or disconnect the battery. once the computer has reset to factory defaults, turn on the ignition and fully rotate the throttle to full open twice. this resets the tps.

now restart the bike.

what you will probably notice is that the bike runs rough at first. as the motronic collects data and tunes itself in, it should smooth out a little.

It's not a chip. It's a piece of wire with a spade connector at each end, stuck in a plastic box. Removing it defaults the bike to run rich. The exhaust gas analysis tests done on mine indicated too much unburnt fuel was getting into the system with the CCP removed. I'm now running a jumper wire to simulate R1150RT ?? settings (Brown box instead of yellow).

Can anyone recall the correct pin numbers for the different configurations and save me the trouble of looking at mine tonight? Renagade has asked, but I don't have them written down and can't find the thread that discussed this. Otherwise, I'll check my bike tonight. I know my service guys ran mine with a couple of configurations (including no CCP) and went to the Brown configuration as the best option.

Found this. Thanks to CycleRob. I'm running pins 86/87 (Brown)
--------------------------------------------------------------------------------

The CatCodePlug is just a jumper terminal that chooses specific Motronic fuel/ignition programs according to what country the bike is sold in. They're different colors to easily ID what country and terminals are jumped. Since there is no key-off voltage on the female terminals, i see no need to reset the Motronic, with fuse removal, when you want to make a change for reasons I describe at the end. Here's a copy-n-pasted outline I saved about them:

Yellow: R1200c, R1100s, R1150r, R1150gs, R1100rs, R1100rt P/N 8 366 282

Pink: R1150rs, R1150rt, R1100r, R1100gs P/N 8 366 625

The Brown CCP connects the 86+87 pins together. The Yellow one connects the 30+87 pins together.
The 87 pin is the common one for all CCPs
Each of the 6 CCP maps has a nominal name. The Yellow CCP gives the "USA" map, which is also what Australian bikes came with. Removing the CCP gives the "EURO" map. Running the Pink or Olive green CCP will give you RS/RT maps. You can also use the grey "Bad Fuel" CCP that came with the GS Adventure to get that map. There may also be an unused R1100S map on the chip as well.

When studying the CCP's socket ! saw there are some slots with no metal terminals in place. As luck would have it you can electrically remove the Yellow CCP just by plugging it back in a quarter turn CCW from its original installed position. Factory original is where the 2 terminals are in the right-front area of the socket and the CCP's top mounted removal tab goes right&left. When it's in the installed & electrically disconnected position the terminals are front-left and the top tab goes front-2-back. No other plug in position is possible as the female slots do not match. The reason you may want to take the CCP with you would be to cover the open female terminal -AND- have the ability to reinstall the CCP correctly so the bike will get maximum fuel economy on a long, 1+tankful highway trip. In the OutBack, range could matter!

Recapping . . .
tab goes right&left = it's working
tab goes front-2-back = it's not

Apparently you can fool everybody but good BMW techs

When my bike was new it surged like a bucking bronco at a constant speed at low revs...and by removing the yellow CCP fixed it.

MIXR is right..removing it puts it in its Euro mode and will not try to run so lean..you may loose a little in economy but I would rather that than surge.

I also found our here that you do not have to remove it to de activate it..you can just rotate it 90 deg and plug it back in..so you don't loose it.

Anyway...After my last BMW service I noticed the surge was back..I put up with it for a few weeks..it was pissing me of and I checked under my seat.

Sure enough..He had rotated the CCP back to its correct position..I moved it back and the surge is now gone.

If I am doing a big trip I may rotate it back if but I don't think the fuel saving is very much.

Here's a pic of mine (CCP)..showing it in it's correct possition.

I'm not going to comment DJ - But I'm sure others will! Something about guns and liking people?

Mixr: Do you have or do you know where I can find the Pin Out information for the different colours. This I think could be a really useful thread

riceburner · Post by **riceburner** » Wed Jun 20, 2007 3:13 am

None of my Rocksters ever had a CCP box.

Single650 - Sorry mate - I can't find the info I had on what the pin configurations were. I know it's been laid out in a report for the R1100S, and has been done here in the past, but I've no idea where. I'll have a look.

The pics below are what was done to my bike when the Yellow CCP was ditched. I know that even BMW dealers have removed the CCP to 'help' cure surging, but gas analysis suggests it's not a good idea. Very contentious issue. When mine was removed, I got bad fuel economy and too much 'soot' over the back end.

This is taken from the left side of the bike for orientation:

And this is a close up of the new configuration:

As far as I know UK spec don't have the unit.

I would like to know so I can try remapping, it is good if you get surging and can improve performance/economy.

I don't like secret bits of my bike that BMW thinks I shouldn't know.

Thanks Mixr

Good info here as well - This is the 1100S article.

I'd rather have the bike running rich than lean!

MIXR · Post by **MIXR** » Wed Jun 20, 2007 4:21 pm

And that's why you do an exhaust gas analysis! Mine does not run 'lean'. It's had the jumper wire in place since 30,000 kms. I'm now at 95,000 kms. Running 'rich' was just pumping unburnt hydrocarbons (fuel) out the exhaust and washing the upper end of the combustion chamber. It can be just as detrimental to engine life as a lean mixture. As I said - There are as many opinions on this topic as there are CCP boxes! I'm happy with my fuel economy and performance.
