The CANflex ECA works as an ethanol content analyzer, E85 analyzer, and Bluetooth flex fuel analyzer in one compact system. It reads your fuel mixture using a genuine Continental® ethanol sensor and outputs the data through CANbus, Bluetooth, a built-in LED display, and 5v output for legacy support.
Perfect for Hyundai 2.5L Turbo owners running E85 blends or wanting accurate real-time ethanol data for JB4 or other tuning systems.
