Product Description

The Innovate Motorsports 3904 MTX-D Gauge Kit provides real-time monitoring of ethanol content and fuel temperature in a single versatile digital unit. Its 52 mm gauge design fits standard pods, and customizable faceplates and LED indicators let you match the look to your cockpit. The external LED can show ethanol blend or warn of fuel-temperature thresholds.

With error-flagging for faulty sensors and dual 0-5 V outputs, the MTX-D supports standalone ECUs, data logging systems, or boost controllers. It's capable of reading full ethanol blends (E0-E100) and fuel temps from -40 to +257 °F. OBD-II compatibility simplifies setup across platforms.

Whether you're tuning flex-fuel vehicles or tracking fuel system performance, the MTX-D gives essential data in a clean, modular form. It's built with tap-and-lock connectors and programmable display/settings, making it a perfect choice for engine tuners and performance rigs.
