Coding Plug Information
The Rhine West Performance software for “R” series motorcycles is tuned around two types of exhaust systems: the “high back-pressure” version and the “free-flow” version.
The “high back-pressure” versions includes the stock exhaust system, and various aftermarket manufacturers. Typically any exhaust system that uses a diversionary baffle system, increases the pressure on the exhaust gasses and should run on the stock exhaust system setting. This tuning map is accessed by having the stock coding plug for the motorcycle installed.
The “free-flow system” is any exhaust system that would be considered “free-flow” or a “straight pipe”. This tuning map is accessed by removing the coding plug from the motorcycle.
The coding plug determines various tuning maps that the control unit uses to run the engine. By removing or installing the stock coding plug, the owner can switch between maps tuned for “free-flow” exhausts systems or “high back-pressure” exhaust systems.
We have seen some coding plugs that are modified from the stock condition, meaning that the internal jumpers have been cut inside the coding plug. To check the coding plug, simply find the resistance between the pins of the coding plug. If the coding plug is properly configured all pins should be a closed circuit to one another.
Each
U.S. specification motorcycle was delivered with a particular coding plug installed.
The chip is designed to run with this coding plug in place when the high back-pressure
exhaust system is installed on the motorcycle. To determine the correct coding
plug for your motorcycle see the chart below.

Coding Plug Location
The coding plug on the R motorcycles is located in the relay box. The relay box location is dependent on the model of bike you have.
R1100S
In order to view the coding plug on the R1100s the left fairing must be removed. The picture below shows an R1100S with the coding plug removed. The arrow points to the socket that the yellow coding plug would fit in.
R1200C
The coding plug on the R1200C is located under the fuel tank under the control unit. The picture below shows the location of the coding plug on the Cruiser.
R1150RT, R1150RS, R1150R, R1150GS, R1100RT, R1100RS, R1100R, R1100GS
The coding plug for these bikes is located under the seat in the fuse box. The picture below shows the coding plug removed.
