Coding Plugs R1100, R1150 Decoded

[lowndes]

Racer7,,

I had the same experience with my '99 R1100S when I installed the AF-XiED two months ago. SOOOO much smoother, EASY to use at low RPM's, not nearly so cold natured, it even sounds better. It's the way the engine is supposed to run.

I bought an old '99 RT last weekend, will go pick it up next weekend. The AF-XiED for it came today.

New Coding Plug Data

Hello everybody
I have a 2002 r1150GS single spark (ABS II but "BMW" on brake calipers) that came, used, without any code plug.
I made 8 combinations (that is all possible, considering 30 is earth)
Here are the results

2002 R1150GS EU Single Spark
No Coding Plug : R1150R/GS ECE Kat ECU Code Variant 0 Lamda Control: Lamda sensor
30-87 (Yellow ) : R1150R/GS US u.TEV ECU Code Variant 1 Lamda Control: Lamda sensor
30-87a (Beige) : R1150RS/GS CH o.TEV ECU Code Variant 2 Lamda Control: Lamda sensor
30-87-87a (Pink) : R1150RT ECE/US Kat/T ECU Code Variant 3 Lamda Control: Lamda sensor
30-86 (Olive Green) : R1150RT US II Kat/TE ECU Code Variant 4 Lamda Control: Lamda sensor
30-86-87 : R1150 R/GS ECE ROZ91 ECU Code Variant 5 Lamda Control: Lamda sensor
30-86-87a (Blue) : KEINE SERIE ECU Code Variant 6 Lamda Control: Lamda sensor
30-86-87-87a (Brown) : KEINE SERIE ECU Code Variant 7 Lamda Control: CO

from the common data with Roger's, I assume that it might be the the same as
"2002 R1150GS CA (Canada) Single Spark" and "2002 R1150GS US Single Spark".

Roger, you can add them to the original collection, if you want to.

I plan to do some statistical analysis with the data from various configurations (spark advance, closed/open loop, O2 sensor values) and I will post them when ready.

By the way does anybody know what is the differrence between "US II KAT/TE" and "US KAT/T"?

Nice work. That's a very complete list. There is no difference between T, TE and TEV. There is a 20 character limit in the memory space that holds that string of letters. If there wasn't they would all read as TEV, which I believe is an acronym for our "charcoal canister system" but in German.

I believe that u.TEV and TEV means it supports the canister and o.TEV means it expects no canister. But the TEV is also intermixed with the CH designation which others have said means for Switzerland. Some Coding Plugs also mention Japan. I tried the Japan variant in my 2004 R1150RT and noticed that the bike performed worse.

Thanks Roger.
I am still trying to find what are the differences between EU(ECE), US and CH(Swiss) tables. The only difference I have found up until now is that EU stays longer in open loop mode after strong acceleration or deceleration, also turns to open loop with smoother desceleration than the other two.
The ignition timing is more or less the same.
Still collecting data (with gs-911) for further analysis.
Even if it is of little use, its a nice game anyway!

Given that each jurisdiction (US, ECE, etc.) has its own pollution measuring protocols, it would make sense for BMW to tune the Open/Closed Loop are, ignition timing and other parameters to give the best results for each test protocol.

I've been doing some work on my 2001 R1150GS and decided to map out the coding plugs. I gave all 8 different codes using 30: 86, 87a, 87. In this earlier R1150GS with ABS I (or is it II), it turns out the factory installed Motronic MA 2.4 only has 3 valid maps of the 8 that are possible. Here's what I found:

2001 R1150GS Single Spark
No Coding Plug: R1150 GS ECE Kat (A European 1150GS with Catalytic Converter)
Yellow Coding Plug: R1150 GS US u.TEV (A United States 1150GS with Charcoal Canister and Catalytic Converter)
Beige Coding Plug: R1150 GS CH o.TEV (A Swiss 1150GS without Charcoal Canister but with a Catalytic Converter)
Pink Coding Plug: keine Serie
30-86 Coding Plug: keine Serie
30-86-87: Keine Serie
30-86-87a: KEINE SERIE
30-86-87-87a: KEINE SERIE

This is the smallest set of maps I've seen yet, and this particular date-code Motronic is only set up to handle the GS model. This is something to keep in mind when one purchases a used Motronic. Note the capitalization difference of Keine Serie (not for any series of motorcycle). It looks like the maps were modified and deleted at different times by different designers.

The motorcycle came with no Coding Plug installed and I've been doing some simple tests with each of the three different plugs.

The moral of the story continues to be, don't assume anything about what a given (e.g. Yellow) coding plug will do. In order to know you've got to read the Motronic with a GS-911.
