Keep an Eye on Your Air/Fuel Ratio

July 2022 Products

Your engine’s air/fuel ratio is critical to improved performance, especially if it’s a turbo or supercharged engine. The best way to keep an eye on your air/fuel ratio is by measuring oxygen levels in your exhaust system with an Innovate Motorsports Wideband Air/Fuel Ratio Gauge.

The gauges feature DirectDigital signal processing and Advanced Sensor Control that samples oxygen sensor data faster and more frequently so you get a real-time picture of the air/fuel ratio at any point in the engine’s powerband. They also have a serial in/out for use with Innovate’s Modular Tuning System (MTS)-enabled devices to add additional logging channels. Data can be logged on your PC with free LogWorks software. The gauges are compatible with gasoline, diesel, and E85 fuels. 

MTX-L and MTX-OL Plus Gauges

Innovate’s MTX-L Plus air/fuel ratio gauge has an advanced oxygen sensor heater control for more accurate readings—a big plus with boosted engines. Other features include:

• Large digital readout and programmable “digital needle” provides the functionality of a needle gauge with pinpoint digital accuracy
• Digital display in AFR or Lambda
• Digital and analog inputs and outputs
• Customize the gauge with included interchangeable faceplates and bezels
• Bosch LSU 4.9 wideband O2 sensor included

The MTX-OL Plus gauge does the same thing the MTX-L does, but has an easy-to-read, high-contrast OLED display. The MTX-OL also has a configurable linear 0-5 volt analog oxygen sensor output for use with piggyback or stand-alone ECUs and external dataloggers.

DLG-1 Dual Lambda Gauge

The DLG-1 allows you to monitor the left and right exhaust banks of a V-style engine at the same time. No PC is required for additional configuration and the sensors install easily with plug-and-play connections. The user-configurable OLED display (AFR or Lambda) provides multiple ways to display data. The DLG-1 has a configurable linear 0-5 volt analog output for use with piggyback or standalone ECUs as well as external dataloggers. Two Bosch LSU 4.9 wideband oxygen sensors are included.

PSB-1 PowerSafe Boost and Air/Fuel Ratio Gauge 

The PSB-1 combines an air/fuel ratio gauge with a boost safety override in one unit. It has a programmable boost safety that allows you to cut boost by pressure or by a lean air/fuel condition. Other features include: 

• No PC required for configuration
• User-configurable OLED display—view AFR, Lambda, inHG, PSI, kPa, or BAR
• 4 BAR MAP sensor
• Peak hold function
• Configurable linear 0-5 volt analog output for use with piggyback or standalone ECUs and external data loggers 
• Log three channels of data—air/fuel, MAP, and RPM
