This is an important gauge especially for those with cars that have forced induction to provide them as well as their tuner with solid data and accurate air fuel ratios. This particular gauge features Innovate's patented DirectDigital wideband sensor control which provides 100% digital wideband technology. This is a 52mm gauge that has a built-in digital wideband controller which reduces wiring to simplify installation. The sensor provided in the kit is compatible with all fuel types for those of you who switch between leaded race fuels, E85, or pump gas. It is also compatible as you can configure it with the 0-5v analog output for those that need data on a piggy back or standalone ECU. Included with the Innovate Motorsports NTX-L PLUS Wideband Gauge will be an LSU 4.9 Wideband O2 Sensor, a weld-in bung for the sensor, 8ft of wiring harness, and a faceplate with miscellaneous hardware to make this gauge ready for installation.
