Run E85 with confidence. The BMS CANflex kit gives your B48 or B58 Supra a clean, accurate way to read ethanol content and send that data directly to your tune.
This complete flex fuel kit, 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 Toyota Supra owners running E85, adding port injection, or wanting accurate real-time ethanol data for JB4, MHD, BM3, or EcuTek tuning.
Our new CANflex ECA sends your ethanol mixture four different ways for the ultimate tuning integration:
Offered in both a plug and play harness and a universal harness. Manual transmission vehicles and BM3 require using the universal harness with posi-taps for CANbus.
The complete kit with the BMS CANbus ECA includes:
