Innovate MTX-D Ethanol Content + Fuel Temp Gauge Kit (Sensor NOT Included) | 3912

The Innovate MTX-D Ethanol Content & Fuel Temperature Gauge is a compact, high-precision digital monitoring solution designed for performance vehicles running flex-fuel, E85, or ethanol-blended gasoline. Built on Innovate Motorsports’ proven MTX Digital platform, this 52mm (2-1/16") gauge provides real-time ethanol percentage and fuel temperature data to help you safely optimize tuning, ignition timing, and boost control.

Engineered for enthusiasts and professional tuners, the MTX-D delivers accurate ethanol content readings from 0–100% along with fuel temperature monitoring ranging from -40°F to 257°F (-40°C to 125°C). The system is designed for seamless integration into modern EFI setups, helping ensure proper fueling strategy and engine safety when switching between pump gas and high-ethanol fuels.

The gauge features a customizable LED display that can be configured as a fill-style bar or single warning indicator, giving drivers quick visual feedback at a glance. Programmable warning thresholds allow you to set alerts for both ethanol content levels and fuel temperature conditions, helping prevent detonation risks and inconsistent fueling under demanding driving conditions.

With interchangeable bezels and faceplates, the MTX-D can be tailored to match any interior setup while maintaining a clean, OEM+ appearance. The included serial communication interface allows integration with other Innovate MTS-compatible devices for expanded data logging and tuning capability.
