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-1 wideband controller, oxygen sensor & bung/plug, and the award-winning LogWorks engine-tuning 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 DL-32 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.

Note: The G4 gauges have NO serial capability, and can only display AFR. For complete channel and color configurability, and for integrated remote-MTS button (calibrate, log start/stop), see the XD-16.

Installation of the G4 Gauge is relatively simple. Complete documentation is supplied, and the support pages, user forum, videos, application notes and tuner resources can also speed you on your way to effective tuning. Innovate also has a great network of local dealers, tuners, race shops, and dyno shops that can assist you in choosing, installing, and getting the most out of your Innovate products.
