Power supply circuit The power supply circuit obtains power from the battery (12 V) to supply the power (5 V) that is required for operating the ECU. B. Input interface circuits The input interface circuits convert the signals output by all the sensors into digital signals, which can be processed by the CPU, and input them into the CPU. C. CPU (Central Processing Unit) The CPU determines the condition of the sensors in accordance with the level of the signal that is output by the respective sensor. Then, the signals are temporarily stored on the RAM in the CPU. Based on those stored signals and the basic processing program on the ROM, the CPU calculates the fuel injection duration, injection timing, and ignition timing, and then sends control commands to the respective output interface circuits. D. Output interface circuits The output interface circuits convert the control signals output by the CPU into actuating signals for the respective actuators in order to actuate them. They also output commands to the indicator and relay output circuits as needed.

STEP 1 – BATTERY CONNECTION Locate the battery and disconnect the negative battery cable. Mount the module in the open area in front of the battery with 2-tie straps or velcro straps, directing the harness from the module towards the 6 o’clock position. STEP 2 – THROTTLE POSITION SENSOR (TPS): Remove the air cleaner assembly and unplug the TPS sensor connector at the TPS sensor. The harness includes (2) TPS connectors which should be routed under the gas tank into the factory wire loom to the TPS sensor. The TPS sensor is located on the left side of the throttle body. Plug the (2) TPS connectors from the module in between the TPS sensor and to the factory TPS connector. STEP 3 – O2 SENSOR: Systems equipped with factory O2 sensors Rear: Unplug the Rear O2 sensor connector from the factory harness, which is located at the Rear exhaust pipe. Route the module’s harness which includes (2) O2 sensor connectors and connect one connector to the Rear O2 sensor and connect the other connector to the main factory O2 sensor connector. Front: Unplug the Front O2 sensor connector from the factory harness, which is located at the Front exhaust pipe. Route the module’s harness which includes (2) O2 sensor connectors, and connect one connector to the Front O2 sensor and connect the other connector to the main factory O2 sensor connector. Systems not equipped with factory O2 sensors NOTE: Many aftermarket exhaust systems are now equipped with plugged O2 sensor bungs which can be removed to accept an aftermarket O2 sensor. Typically these bungs already have a thread size of 18 mm x 1.5 mm. Exhaust systems not equipped with O2 sensor bungs need to have the supplied 18 mm x 1.5 mm thread size bung welded to the exhaust pipe in order to install an O2 sensor. The O2 sensor bung should be installed 3 to 6 inches away from the rear cylinder exhaust port and in front of the exhaust torque tube pipe area. The module prefers to receive information from the O2 sensor from an area that is NOT contaminated from atmospheric air. This air may enter through the tail pipe of an unrestricted or un-baffled exhaust pipe. The bung should not be installed in the “5 to 7 o’clock” area. If mounted in this area the O2 sensor can be damaged. The moisture from the gases exiting from the rear cylinder exhaust port will harm the ceramic shell element of the O2 sensor.

Oil Temperature and Gauge 2.1. Introduction My 1998 BMW R1100RT came with an LCD temperature gauge that shows horizontal black bars in a vertical motif, to indicate temperature. This is difficult to interpret at speed (how many bars are exposed?) and does not actually tell me what the oil temperature is. 2.2. Normal Operation The bike seems to run at 5 or six bars under normal conditions. It appears that the oil thermostat for the cooler is set to ’5 bars’. 2.3. Over Heating The LCD panel indicates that 8 bars is the maximum normal operating temperature. It would be useful to know what the actual temperature is. Modern oils have a normal operating temperature of approximately 110 degrees Celsius and will not show any serious degradationii at this temperature. The maximum sustained operating temperature (at the bearing surface) is approximately 130 degrees Celsius for any oil formulated in the past 5 years and some high performance synthetics will not appreciably degrade even at this temperature. However, the degradation curve is a polynomial and degradation will increase rapidly with increasing temperature. According to the oil’s formulation (pure synthetics will show the least increase with temperature), by approximately 160 degrees Celsius (or about 300 degrees Fahrenheit), oil degradation can be up to 10 times faster then at 110 Deg. C. 2.4. Scale To fix the ‘number of bars’ problem, I determined that an overlay with numbers would be the best idea. 2.4.1. Addendum The number scale became too much to maintain. Rather than this, I cut a mm or so wide stripe out of the self sticking stripping meant for the side of a car. Using a red material, I put it through the middle of the fifth bar of both the temperature and fuel display. The stripe is slightly smaller than the thickness of the bar. This allows me to tell when I am at normal operating temperature and when approximately half a tank is used

1. Turn off the ignition switch before proceeding. 2. Select a convenient mounting location for the Bosch sensor. In general, the sensor should be mounted as close to the exhaust valve or exhaust manifold as practical. When choosing a mounting location, allow several inches clearance for the sensor wire harness. The wire harness must exit straight out from the sensor. Do not loop the harness back onto the sensor body. The sensor responds to oxygen pressure. Excessive backpressure will cause a reading error. For turbocharged applications, you must mount the sensor downstream of the turbo. 3. For temporary use during dyno tuning, you can mount the Bosch wide-band sensor in place of one of the original equipment rear oxygen sensors (after the catalytic converter). You can also use a sniffer in the tailpipe. For permanent mounting, an 18 x 1.5 mm weld nut must be welded onto the exhaust pipe. After welding, run an 18 x 1.5 mm tap through the threads. Failure to clean the threads may result in sensor damage. Note that most automotive muffler shops are familiar with oxygen sensor weld nut installation on custom pipes. Do not install the sensor until after the free air calibration procedure described in the following section. Always use an anti-seize lubricant such as Permatex 133A on the sensor threads. 4. Install the WEGO II unit. The WEGO II unit should be mounted where the LCD display will be visible during testing. You can secure the WEGO II unit with Velcro tape strips. 5. Connect the Bosch sensor to the 6 pin mating connector on the WEGO II wire harness. 6. Refer to Figure 1. Connect the black WEGO II wire to frame ground using the supplied ring terminal. Try to use an existing wire harness ground location. Do not extend the WEGO II ground wire or ground the WEGO II to the battery minus terminal or to the engine. 7. Connect the red WEGO II wire to switched +12 volt power. You can usually find switched +12V power at an accessory fuse on the fuse block. You can use the supplied fuse tap and 3/16″ female crimp terminal for this purpose
