G4 Gauge

The G4 Air/Fuel Ratio gauge (52mm, 2 1/16”) features a high-speed stepper motor, through-dial backlighting, and an illuminated pointer. Each kit includes the gauge, an LC-2 wideband controller, oxygen sensor, serial cable, bung, and the award-winning LogWorks engine-tuning software.

Key benefits of the “G4” kits include:

  • The industry’s most accurate and fastest-responding wideband controller.
  • One additional available analog output (one connects to the gauge).
  • Easy set up and wiring (instructions included).
  • LC-2 includes Innovate serial in & out for adding additional modular tuning system (MTS) components. (Gauge itself is analog only- no serial).
  • Illuminated needle and through-dial backlighting.
  • Log directly from the LC-2’s digital output into laptop w/included software:

For tuners seeking the most cost-effective way to start monitoring Air/Fuel Ratio, the G4 gauges offer an attractive option, while opening the world of true digital data acquisition and software engine analysis. For example, users can add multi-sensor interfaces (starting as low as $129), and log 5 critical parameters directly into any PC or laptop. Or they can get a PL-1 data logger for hundreds of hours of 32-channel data logging on an SD card. Best of all, the G4 gauges include the powerful LogWorks software for synchronous high-speed logging of wideband data, other MTS sensors, and data from a growing list of “piggyback” fuel controllers and standalone or factory (OBD2) ECUs. This is the same software used by champion engine builders and racers.

The G4 Gauge ($99) can be purchased as an accessory to be used with the LC-1, LC-2, LM-1, or LM-2.. These kits includes the G4 Gauge, mounting hardware, and quick-start guide.

The G4 Gauge Kit ($249) comes complete with the patented award-winning LC-2 Wideband Controller, G4 Gauge, Bosch 5-wire Wideband 02 Sensor, Bung, Serial Cable, LogWorks Software (Free Download), and instructions.

Note: The G4 gauges have NO serial capability, and will only display AFR in the Gasoline scale.
