Product Description

The Innovate Motorsports 3912 MTX-D Ethanol Content & Fuel Temperature Gauge Kit is a versatile digital gauge solution built for tuners, racers, and performance enthusiasts. Designed with a 52 mm digital display, this gauge provides accurate ethanol content percentage readings (0-100 %) and fuel temperature data (-40 °F to 257 °F) in a single package, making it ideal for vehicles running E85 or flex-fuel setups as well as any project where fuel temperature monitoring is needed. Unlike single-function gauges, the dual function of the 3912 gives you two critical engine parameters in one modular device.

Installation is universal and not vehicle specific, requiring only proper power, ground, and gauge mount space. The kit includes interchangeable faceplates and bezels for a custom look, a locking wiring harness for simple hook-up, and an innovate serial programming cable for connecting to other Innovate devices or data logging software. While the ethanol sensor is not included, this kit supports external ethanol sensors when added, allowing for full functionality in flex-fuel monitoring systems. Ideal for street builds, race cars, or any enthusiast tuning setup, the Innovate 3912 MTX-D kit adds precision monitoring to help you tune and protect your engine more effectively.
