The Innovate Motorsports MTX-AL Wideband Air/Fuel Ratio Gauge is a great way to monitor the air fuel ratios, and make sure everything is copasetic running wise. If you have a boost leak, exhaust leak, bad plugs, then these things can affect your air/fuel ratio. But more importantly you want to make sure that your tune is within a healthy range under peak boost. If you’re boosting under lean conditions, then things will melt, stretch, break, kaboom.
Included with this gauge is the Bosch LSU 4.9 wideband O2 sensor which you can calibrate for maximum accuracy. This also includes an 8ft sensor cable to provide the user with several mounting options. A program serial cable is also included, and a quick start guide is supplied to help you with installation.
