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.

. Interface Buttons - Pressing either the left or right interface buttons will allow you to cycle through the 4 different display modes. - From the main screen, pressing and HOLDING the left interface button will put the gauge in setup mode. Once in setup mode, 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.

3. Configure the gauge as desired by changing the gauge face and/or bezel. 4. Make sure every piece is positioned correctly using the locating tab and reassemble the gauge. 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.
PAGE 5
3 Connect the WHITE wire to a headlight power wire (a wire that goes hot with 12V when the headlights are on)). This enables the display to dim for better nighttime viewing. DO NOT CONNECT THIS WIRE TO THE HEADLIGHT DIMMING WIRE. Connection to this rheostat type of switch will cause the gauge to malfunction. If you chose not to utilize the dimming feature, connect the WHITE wire to ground.
PAGE 6
2.2 Gauge Mounting and Routing The SCG-1 gauge fits in any standard 2 1/16” (52mm) gauge pod. Mounting of the gauge should be done in such a manner that the cables are not being forcefully pulled and strained from the gauge itself. Route the sensor and solenoid cables avoiding contact with the exhaust system and other vehicle 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.

2.3.2 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. 8 - 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.

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. it is time to perform the sensor calibration. Innovate Motorsports’ ‘Direct Digital’ wideband measurement principal allows you to calibrate the sensor to compensate for sensor wear. This procedure takes just a few moments and it will ensure the most accurate readings throughout the oxygen sensor’s life. This procedure is required anytime a NEW oxygen sensor is installed.
PAGE 10
Race Application - Calibrate before first installation of new sensor - Calibrate once per race weekend 3 3.1 Boost Controller Setup Entering Setup Configuration The SCG-1 can be configured directly from the gauge itself or by connecting it to a computer with the LM Programmer software. 3.1.1 Configuration using SCG-1’s interface buttons 1. From the main screen, press and HOLD the left interface button to put the gauge in setup mode 2.
PAGE 11
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. Wideband O2 Units (WB O2 Units) – Allows the gauge to display O2 units in either AFR or Lambda. Default setting is AFR. 2. MAP Units - Allows the gauge to display pressure in either inHG/PSI or kPa. Default setting is inHG/PSI 3.
PAGE 12
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. Note: Because of flow restrictions, wastegate spring size, and other factors, not all applications will be able to achieve desired target boost pressure. 2. Gain – Ramps up the solenoid Duty Cycle to help with boost pressure drop at high engine speeds.

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 4.9 PSI and 13 AFR. Tuning Tip: Set the Start Pressure at the same pressure value as Spring Pressure. 6. Boost Control ON/OFF – When configured from the gauge, this setting is accessed from the main screen. Press and HOLD both the left and right interface buttons, this will disable/enable solenoid control.

4. The installer will start, follow the prompts to install the software. 5. Once the software has been installed, the LogWorks software, LM Programmer, manuals, and tools can then be located by navigating through Start->Programs->LogWorks3. 4.2 LM Programmer LM Programmer is used to configure settings on your SCG-1. 1. Connect the OUT port of the SCG-1 to the provided serial programming cable. Connect the other end of the serial programming cable to your computer.
PAGE 15
By selecting the ‘use Air-Fuel-Ratio’ button you can change the displayed unit of measure for mixture by AFR instead of Lambda. This does not change the programming, only the unit of measure displayed in the configuration screen. Click the ‘Program’ button to upload your modified A/F or lambda scaling data into the SCG-1. Once the unit has been programmed, the ‘Program’ button will grey out. Factory Programmed Default: The analog output by default is programmed to output between 0V at 7.35 AFR to 5.

1. Connect the SCG-1 to the computer and launch LM Programmer. 2. Once connected, LM Programmer will display the current version of the firmware that is installed in the SCG-1. Do not update the firmware if the versions are the same. 3. On the ‘Info’ tab of LM Programmer you will see a button labeled “Update Firmware,” click this button. 4. Select the firmware file with the dld extension.

Error 9 Supply Voltage too low Supply voltage too low for sensor regulation 4. Replace sensor. 1. Verify you have 12V at your power source and the circuit can support a 3 amp draw. In an O2 error state, all solenoid functions are automatically disabled. To continue using the solenoid functions without the safety cuts, the wideband function of the SCG-1 may be disabled from the setup menu.
