ECB-1 BOOST Ethanol Content % & Air/Fuel Ratio Gauge Kit Description

  • Boost Vision: real-time approximation of your ECU’s boost limit
  • OLED user configurable display (one, two, or four channel viewing modes)
  • Ethanol %, Vacuum/Boost, Target Boost, Peak Boost, Fuel Temp, Air/Fuel ratio
  • Wideband O2 Compatible with several fuel types (Leaded, Unleaded, Diesel, E85 & more)
The ECB-1 Ethanol Advanced gauges from Innovate Motorsports combine their patented DirectDigital™ O2 sensor control technology with application specific sensors, an OLED display, and a sophisticated ethanol content sensor that also measures fuel temperature. These capabilities allow the user to monitor and capture critical metrics for accurate and reliable tuning while operating with high ethanol content fuel.

This four in one gauge allows you to monitor ethanol content percentage, fuel temperature, fuel pressure, and wideband air/fuel ratio gauge on an easy to use and configure OLED display. It displays in all of the following: °F or °C, AFR or Lambda, PSI, kPa, or BAR, and has an on-screen error reporting function for the ethanol content sensor and wideband O2, as well as a warning indicator LED for low fuel pressure.
