Hi aksel13,

Read JohnGS1100 Tuning Chip thread about 10 threads down from yours there is a wealth of info, the following was copied from page 12 #183.

Get yourself one of his chips I have one and it really transforms the bike.

Yes there are different setting of maps by using a different CCP plug.
Example for R1150 the seting CCP 30 87 is for a normal AFR, for setting 30 87 87a is for a little richer AFR (large intake tubes, de-cat free air filter, camshafts) and for 30 86 87 or 30 86 87 87a is for using low octane petrols..

CCP settings is similar as the stock chip settings.

So : pin 30 is ground, 86 is for low octane petrols.

For R1150 :
Pins 30 87 stantard setting (GS-R).
Pins 30 87 87a is for all R1150 with large intake injection tubes from RT-RS.
And when connect the pin 86 at all up settings, is for using low octane petrols.
There are no settings for R1150 without lambda connection.

For R850-1100.
Pins 30 87 87a is for GS-R with lamda connection.
Pins 30 87 is for GS-R-RT (fiting large intake injection tubes).
Pins 30 87a is for all R850-1100 without lambda, byt with narrow intake tubes from GS-R.
No CCP is for all R850-1100 without lambda with large intake tubes from RT-RS.
And when connect the pin 86 at all up settings, is for using low octane petrols.

The coding plug allows BMW to minimize the number of different ecus it has to stock. Each ECU can run 8 different motorcycles.

There are different intake tubes, exhausts, heads, cam shafts, compression ratios and octane specs for the various models of R1100, R1150, etc.

The coding plug consists of four wires. One is ground and three are inputs to the Motronic. By grounding the three Motronic inputs in various combinations the coding plug can select one of 8 sets of maps in the Motronic. Each set of maps is roughly 75 maps/tables. In other words the coding plug selects the set of 75 tables that are right for your bike.

On the r1150 all maps are equally fueled. That is to say they all end up producing the same afr because fueling is controlled by the setting of the O2 sensor, not the coding plug.

For the R1150GS,
No plug means closed loop fueling for US+ECE regular fuel
Yellow plug means closed loop us+ECE 91 Oktane
A 30-87a plug means closed loop Japan octane

Get the best result by using the stock plug designed for your bike.

P.S. On the R1150 Pin 86 is not a low octane pin. It can mean Japan R1150 RT or R1100S depending on what other pins are used with it.

so in my case my plugs look like 87a and 87. what it means to my bike i still feel ignorant about it :blast

What you have is/was referred to as the "Steptoe link" from as far back in 2004.
