The MTX-L Wideband Air/Fuel Ratio Gauge is a dash-mount gauge kit that combines digital wideband accuracy and an affordable price! The digital wideband controller is built right into the gauge, so no separate wiring or control module is required. A large digital LED readout plus a 270-degree sweep "digital needle" combines the accuracy of a digital gauge with the instant recognition of an analog gauge. The gauge even features interchangeable faces and bezels to match your existing gauges!

The complete kit includes everything you need:

Digital, water-resistant 2 1/16" dash-mount gauge
Bosch LSU4.2 wideband O2 sensor
Exhaust weld bung
Programming / data logging cable
Software CD
Silver bezel, black bezel, white dial face, and black dial face
Sensor cable (choose 3 foot or 8 foot)

The gauge has two programmable analog outputs (0 to 5v) for data logging and engine management systems. Displays Lambda (0.5 to 1.52) or ratios for gasoline, diesel, methanol, E85, or LPG.

A must for carb tuning

Comments about MTX-L Wideband Air/Fuel Ratio Gauge:

Tuning Webers is a bit of a black art with much written about it, but this gauge makes it much easier. I set the main jets to a A:F of around 12.5 at idle but could actually see the mixture richening up as I full-throttled down the back straight at Mid-Ohio. A quick change to the air correction jet and I was 12.5-13.0 all the way down. Never would have known that without the MTX.
