## Overview

The M-300 Tuner Edition by PLX Devices is a high-precision wideband air-fuel ratio tuner featuring a built-in 4-digit display and the ability to daisy chain up to 32 sensor modules. Utilizing advanced digital PID and DSP technologies, it delivers rapid, accurate AFR measurements across multiple fuel types. Designed with durable extruded aluminum housing, it operates reliably in extreme conditions and supports standalone use or integration with third-party hardware, making it an essential tool for professional-grade engine tuning.

## Description

The M-300 Tuner edition has ALL of the same features as the SM-AFR with a built in 4 digit display. It accurately measures the precise wideband air fuel ratio (AFR) of any internal combustion engine. Up to 32 SM-AFR modules can be daisy chained together in the iMFD system. M-300TE can also be used as a stand alone unit capable of interfacing with 3rd party hardware. All Sensor Modules are housed in high quality extruded aluminum designed to operate even in the most extreme conditions. In addition, all SM modules offer outstanding digital accuracy, response and resolution which far exceeds that of a standard gauge. Works with gasoline, bio diesel, ethanol, methanol, E85, LPG, and CNG. M-300TE utilizes the latest digital PID and DSP technologies to maximize o2 sensor reaction time and accuracy without compromising overshoot, and slow settling response time. This technology is coupled with advanced self sensor calibration circuitry and sensor soft start to both prolong the life of your oxygen sensor as well as eliminating any user intervention for manual sensor calibration. PLX widebands may be used and installed in your vehicle permanently.
