1. SCG-1 The SCG-1 is a boost solenoid controller gauge with an integrated wideband AFR (lambda) control. The SCG-1 also has advanced safety boost cuts based on AFR and/or boost pressure. Although it can be operated stand alone, it has digital I/O for integration with other Innovate Motorsports MTS compatible products and one configurable analog output for integration with ECU’s and 3rd party data loggers. The following section will help you get familiar with the SCG-1. 1.

- - pressing and HOLDING both interface buttons together will move you to the menu or main screen. The gauge will revert back to the main screen if no there have been no button presses for 15 seconds. From the main screen, pressing and HOLDING both the left and right interface buttons will disable/enable solenoid control. If there are no other error codes on the status viewport of the screen, the SCG-1 will display “SC OFF”.

5. Reinstall the three #2 phillips screws verifying that the buttons are not binding on the gauge lens. 2 2.1 Installation Wiring The SCG-1 has 5 stripped wire leads: 1 Connect the RED wire to an isolated switched 12V source in your vehicle. A switched 12V source goes ON as soon as “key on” power is active. The circuit to which you will pull power from should be able to support a 3 amp draw. Make sure this connection is protected with a 5A fuse (not supplied.
PAGE 5
4 Optionally, the YELLOW analog output can be connected to the analog input of other devices such as data loggers or ECUs. If this wire is not being used isolate and tape it out of the way. The default analog output configuration is 0V = 7.35 AFR and 5V = 22.39 AFR. 5 Optionally, the PURPLE wire can be connected to a tach signal to log engine RPM and to use the shift light function.

components that could damage the cable. Also avoid routing the cables near ignition components or other sources of RF (radio frequency) and EMI (Electromagnetic interference) noise. 2.3 Solenoid Installation - 2.3.1 Mount the solenoid in a suitable location away from high temperatures or near ignition components. Secure hoses with cable ties. Make sure not twist or pinch any of the hoses. The solenoid will make audible clicking noises when in operation, this is normal.
PAGE 7
2.3.2 2.4 External Wastegate MAP sensor 1. The MAP sensor MUST be installed with the hose fitting facing down. It is very important that the sensor be isolated from heat sources, mounted away from all ignition and/or other potential RF emitting sources, and protected against excessive vibration. The MAP sensor has two 1/8” holes that can be used to secure the sensor. Another viable option is to use double-sided mounting tape. 2.

accurate readings. Using a bung is the preferred method for mounting the oxygen sensor in all applications.  Weld the bung at least 24 inches after the turbocharger.  Using a clock as reference, mount the bung between the 9:00 o’clock and 3:00 o’clock position. Welding the bung in the lower section of the exhaust pipe can result in sensor damage caused by condensation making contact with the sensor’s internal heating element.  A 1” bung (provided in the kit) will best protect the sensor.
PAGE 9
As the O2 sensor measures the oxygen content of the exhaust gas to provide an accurate O2 reading, even a small pin-hole leak in a poorly welded sensor bung will effect the accuracy and performance of your O2 sensor. Remember, any deviation from the instructions provided for proper sensor installation will lead to inaccurate O2 readings. 2.5.2 Sensor Calibration Once the unit has been wired and a suitable location has been found for both the gauge and the sensor.
PAGE 10
2.5.3 Calibration Schedule Turbo Application, daily driver (tuned rich) - Calibrate before installation of new sensor - Calibrate new sensor again after 3 month of use - Thereafter calibrate twice a year or every 10,000 miles, whichever comes first Race Application - Calibrate before first installation of new sensor - Calibrate once per race weekend 3 3.

2. Power up the SCG-1. 3. Launch LM Programmer. The LM Programmer application can be launched from Start->Programs->LogWorks3->LM Programmer from the Windows task bar. Once you have completed your desired changes, press the Program button on the lower right on the software application. You will know that the SCG-1 has been programmed successfully when the Program button grays out. 3.2 Display Settings (Gauge Abbreviations) 1.

1. Wastegate Duty (WG Duty) – Adjusts the solenoid duty cycle in 2% increments. The higher the duty cycle percentage the higher boost pressure will be achieved over the base wastegate spring pressure. When wastegate duty is active, the SCG-1 will display the duty cycle percentage on the upper right hand corner viewport. Default setting is 4% Tuning Tip: Start small and work up. Do not increase Wastegate Duty if Boost/AFR cuts occur. Remedy Boost/AFR cuts before increasing Wastegate Duty.
PAGE 13
5. Boost Cut by AFR – This is a safety trigger to cut boost by a defined AFR . There are two setup parameters to trigger this safely cut: Start Pressure (AFR Start Press) and AFR Cut. Start Pressure (AFR Start Press) is the minimum manifold absolute pressure where the safety cut will become active. AFR Cut is the defined lean A/F that will trigger the safety cut. When the Boost Cut by AFR is triggered, the SCG-1 will display “O2 Cut” on the upper right hand corner. Default setting is a start pressure of 4.

that includes drivers. Make sure that nothing is connected to the IN port of the SCG-1 2. Power up the SCG-1. 3. Launch LM Programmer. The LM Programmer application can be launched from Start->Programs->LogWorks3->LM Programmer from the Windows task bar. 4.2.1 Programming Analog Output Connect the SCG-1 to the computer and launch LM Programmer. Select the Analog Output tab. The analog output configuration screen shows voltage versus Lambda for the analog output.
PAGE 15
When setting the SCG-1 to the slower response speed settings, the measured mixture data will be averaged over the response time setting before being sent via the analog output. 4.2.3 Updating the Firmware Do not update the firmware if the versions are the same. A firmware update should only be necessary if there has been a new release that specifically fixes a problem that you are experiencing with the controller. 1. Connect the SCG-1 to the computer and launch LM Programmer. 2.

Note: All sensor cables for the LSU 4.9 are easily identified by a ‘4.9’ marking molded on the sensor connector side. Use the appropriate sensor cable for the sensor type as each sensor has a different style connector. Spliced cable can not only affect the wideband’s performance but in worst cases it can damage the sensor and/or controller. Selecting the wrong sensor type to the sensor being used will not only give you erroneous readings and/or errors. It can also permanently damage the sensor. 4.
