It's the evolution of the world's most popular standalone digital oxygen sensor controller! Innovate MTX-L digital air/fuel ratio gauge kits build upon the legacy of the XD-16 by adding simplicity and leading-edge industrial science. They utilize 100 percent digital wideband air/fuel ratio technology; while patented, award-winning DirectDigital signal processing provides data on exactly how rich or lean an engine is running at any load. The self-calibrating circuitry also compensates for changes in temperature, altitude, and sensor condition. Innovate MTX-L digital air/fuel ratio gauge kits feature a digital input/output, two full-programmable analog outputs—and they're ideal for applications such as dynamometers, data acquisition systems, standalone ECUs, and gauges.

Q:

Leaded fuel? Yes. No.

Thank you for your question. The Innovate Motorsports 3918 air/fuel ratio gauge is compatible with leaded fuel. However, this will greatly shorten the life of the sensor.

Needed specifically for reference out put for tuning a twin turbo Escalade. I would have chose the dual sensor, was just a little short on cash. Again, this has the output reference voltage for tuning. Works great.
