Description

This gauge utilizes patented DirectDigital™ technology and Advanced Sensor Control, which processes feedback from the LSU 4.9 O2 sensor more frequently and optimizes heater control. This results in the fastest, most durable, and accurate air/fuel ratio readings available from Innovate Motorsports. The unit features a 52mm (2-1/16 in.) gauge body with interchangeable faceplates and bezels, allowing for customization. Its large digital readout is highly visible and can be programmed to display either Air/Fuel Ratio (AFR) in the range of 7.4:1 to 22.4:1, or Lambda from 0.5 to 1.5. The MTX-L PLUS also offers faster analog output speed, ensuring that the vehicle's ECU receives real-time changes in AFR. For advanced users, it includes Innovate MTS serial communications, enabling integration with MTS-enabled devices for logging additional channels and analysis using LogWorks PC software. The kit comes complete with the gauge, silver and black bezels, white and black faceplates, the Bosch LSU 4.9 sensor, an 8 ft. sensor cable, a 1" exhaust bung, a programming cable, and a manual.
