Innovate MTX-L PLUS Digital Air/Fuel Ratio Gauge Kit 8ft w/O2 Sensor | 3918

The Innovate MTX-L PLUS is a high-performance digital wideband air/fuel ratio gauge designed for precise engine tuning, real-time AFR monitoring, and professional-grade data feedback. Built around Innovate’s patented DirectDigital™ technology, this advanced wideband system delivers faster sensor response, improved heater control, and highly accurate readings for both gasoline and ethanol-based fuels.

Engineers and performance enthusiasts rely on the MTX-L PLUS for its enhanced sampling rate and improved sensor frequency, allowing the ECU or tuning device to react more quickly to changes in air/fuel mixture. This results in tighter tuning control, improved drivability, and safer high-performance operation under boost or high load conditions.

The system includes a Bosch LSU 4.9 wideband O2 sensor, known for OEM-level durability and accuracy, paired with a digital 52mm gauge that displays AFR or lambda in real time. The customizable digital interface includes interchangeable faceplates and bezels, making it suitable for both functional and show-car applications.

Designed for seamless integration into standalone ECUs, piggyback systems, or data logging setups, the MTX-L PLUS also supports Innovate’s Modular Tuning System (MTS), enabling expanded logging and multi-channel data analysis through LogWorks software.
