The M-300 Controller come with two analog outputs, linear wideband and narrowband. Our linear wideband output gives you the freedom to interface with a number of tuning devices, such as data loggers, piggy back fuel systems and stand alone engine management systems. With the narrowband output you are able to completely replace your stock narrowband sensor and "feed" our analog signal directly into your ECU. This eliminates the hassle of welding a second sensor bung on your down pipe. Your ECU will "think" that your narrowband sensor is still there while you're measuring wideband information at the same time!
