Show original supplier description
This gauge utilizes patented DirectDigital™ technology and advanced sensor control to provide faster feedback and optimized heater control, making it Innovate's most accurate and durable air/fuel ratio gauge. The MTX-L Plus features a 52mm (2-1/16 inch) gauge body with a large, bright digital readout that can display readings in either AFR (Air/Fuel Ratio) or Lambda. It is capable of reading AFR ranges from 7.4:1 to 22.4:1 and Lambda from 0.5 to 1.5. The gauge includes a Bosch™ LSU 4.9 Wideband O2 sensor and an 8 ft. sensor cable, with an overall length of 10 ft. This kit includes interchangeable bezels and faceplates for customization, an exhaust bung, a program cable, and a comprehensive manual. The MTX-L Plus also features Innovate MTS serial communications, allowing for integration with other MTS-enabled devices for expanded data logging and analysis using LogWorks PC software. Installation is described as relatively simple, with full documentation and support resources available.
