As the world that is our Mustang hobby continues to evolve and the methods by which we improve ’Stangs’ engine performance become more dynamic, monitoring the mixture of air and fuel has mandatory status. While we admit we’re guilty of making a big deal about an engine’s air/fuel ratio, we certainly won’t apologize for preaching that type of gospel, as the air/fuel value is critical to dialing-in maximum performance.
For today’s typical high-performance applications, air/fuel measurements are made using wideband oxygen sensors, which are placed in a ’Stang’s exhaust stream. When an engine is running at operating temperature, the O2 sensors let the PCM know the amount of air that is necessary to fully oxidize residual fuel in the exhaust gas.
As we’ve explained in past tech reports, engine tuners typically have to manipulate a Mustang PCM’s fuel and timing tables manually, to achieve desired air/fuel ratios for engines that have been upgraded with flow-altering gear. To make such changes, calibration software from the likes of DiabloSport and SCT is used in conjunction with analog or digital air/fuel gauges. As these wideband air/fuel gauges go, their speed—their ability to process exhaust samples quickly—is the one quality that basically separates the good from the not as good.
Most widebands are UEGO-type sensors, which read O2 levels through a sensor-mounted pump (when there is no oxygen, the UEGO-sensor’s internal pump determines the amount of air that’s necessary for achieving Stoichiometric air/fuel; 14.7). Innovate Motorsports offers digital wideband devices, and the company’s all-new, MTX-L Digital Air/Fuel Ratio Gauge (PN 3844; $199) is an instrument that is well-suited for street and race ’Stangs that are dependent on custom calibrations for peak performance.
Here we focus on showing you how easy it is to install Innovate’s new device. The gauge’s speed and accuracy are two of its highlight qualities. However, its DirectDigital Wideband Controller, Innovate’s latest technology, is the feature that really puts the MTX-L in a next-level position among other air/fuel gauges.
