Run E85 with confidence. The BMS CANflex kit gives your Genesis GV70/GV80 3.5L Turbo a clean, accurate way to read ethanol content and send that data directly to your tune.

Know your exact ethanol content in real-time via the CANFlex or JB4PRO app on your smartphone or tablet.

This complete flex fuel kit (FFK), also known as an ethanol sensor kit, E85 sensor, flex fuel sensor, ethanol content sensor, fuel composition sensor, or flex fuel composition sensor, installs in about 30 minutes.

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 Genesis owners running E85 blends or wanting accurate real-time ethanol data for JB4 or other tuning systems.
