EATh setup menu When at the ACh menu press and hold the switch until is displayed then release the switch to enter the tach cylinder selection Press and release the switch to select an output from CYL i for one cylinder to CYL 2 for two cylinder and C4L 4 for a four cylinder output When the desired setting is displayed press and hold the switch until is displayed Release the switch and the next menu will be displayed Note some tachs may require calibration at the tachometer to select appropriate input signal type so please make sure cylinder counts are matched up appropriately Gauge bus simulator 3AU9 The gauge menu is not a critical menu but it will allow the STM 100 to simulate and send data out on the bus to trick the bike into thinking it has a stock gauge still in place This will prevent some trouble codes from appearing but these codes have not been known to cause any problems other than setting the code as more of a status indicator that a gauge isn t connected If you are replacing or removing the stock speedometer you will want to select the SPEEd option so the STM 100 will transmit some data back to the data bus to trick the bike into thinking it still has a stock speedometer present If the stock speedometer is still connected on the bike you shouldn t have to worry about setting this menu and the default selection should be the nonE2. PA COte MoT STM 100 Data Bus Breakout for 2004 2010 Harley Davidson models The STM 100 can be used to simplify the installation of an aftermarket soeedometer and or tachometer on a 2004 2010 Harley Davidson motorcycle The device converts the signals from the data bus into traditional analog signals for a gauge of your choice Outputs are provided for accessory power and ground tachometer signal adjustable for 1 2 or 4 cylinder outputs speedometer signal 8 000ppm in addition to the Check Engine signal normally only available on the data bus The STM 100 plugs directly into the diagnostics port and reads the signals from the ECM so there are no additional sensors to wire In addition to the wired outputs the STM 100 has an LED display that allows you to read and clear diagnostic trouble codes similar to a scan tool Included in the kit you should find Heat Shrink A Manual STM 100 Signal Harness WIRING Locate the four pin diagnostic plug typically found under the seat or side cover near the ECM The STM 100 will plug directly into the diagnostic plug This will provide the power ground and data into the STM 100 Note If you ever need to perform diagnostics or re flash an ECM at a shop or dealer unplug the STM 100 to gain access to the diagnostic plug after the work has been performed simply reconnect the STM 100 to the diagnostic plug All of your previous settings in the STM 100 are saved so
