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.

So far, so good!

Giving the reviews on other sites about this product I was skeptical but I wanted the quickest and most accurate data. Seems to be so far it was user error for the other people.

This gauge is great! Easy to read, easy to calibrate, works well on my 2019 STI!
