User Manual
Warning! 
The Oxygen Sensor used in this device gets very hot in operation.
Do not touch a hot sensor. Do not let a hot sensor touch a combustible surface. Do not use the sensor with or near flammable liquids or gases. Failure to heed these warnings may result in severe burns, explosions, fires, or other dangerous events.

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. |
Channel Displays |
- |
The SCG-1 has four different displays modes that can be cycled |
|
through on the main screen with the left and right interface buttons. It |
|
can be configured to display A/F or pressure as primary channels or |
|
both A/F and pressure in both the primary and secondary channel |
|
viewports. |
2. |
Status or Error display |
-The upper right hand viewport of the SCG-1 is reserved to display the status of the wastegate duty or any error codes that might be present.
-O2 error codes will supersede all other statuses.
-In an O2 error state, all solenoid functions are automatically disabled.
2
3. 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.
-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”.
4. Shift Light
-Illuminates when the trigger shift RPM is reached.
1.1Changing the SCG-1’s gauge face and/or bezel
1.Lay the SCG-1 face down and remove the three #2 phillips screws
from the outside rim of the back plate.
2.
3
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 Installation
2.1Wiring
The SCG-1 has 5 stripped wire leads:
1Connect 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.)
Circuits that share power with the vehicle’s stereo, ignition system, ECU, lighting, or fuel pump should not be used. When in doubt, create an additional circuit using an automotive relay available at any automotive parts supplier. See the next section for a relay installation diagram.
2The BLACK wire should be grounded to a solid ground source. The best possible ground source would be the battery ground (-) post.
If other Innovate Motorsports devices are going to be daisy-chained along with the SCG-1, it is recommended that all devices be connected to a single ground point, ideally the battery ground (-) post.

3Connect 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.
4Optionally, 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.
5Optionally, the PURPLE wire can be connected to a tach signal to log engine RPM and to use the shift light function. A tach signal can be acquired from the negative lead of a coil, ECU, negative lead of an injector, or directly from the ignition box if running a multi-spark (i.e. MSD 6AL).
Note: A tach signal can not be acquired from the negative lead of the coil on vehicles running CDI ignitions. For these applications use the negative lead of an injector or a tach adapter (if available for your model ignition).

2.2Gauge 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.
2.3Solenoid Installation
-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.
-Route the solenoid cable through the firewall, to the gauge and connect to the 2 pin connector.
-Confirm that you do not have any air leaks when the engine idles.
