BMW N54, MOTIV ECA FlexFuel+ CAN Bus / Bluetooth

MOTIV FlexFuel+ CAN Bus & Bluetooth ECA – Real-Time Ethanol Content (BMW N54 / Universal)

The MOTIV FlexFuel+ CAN Bus & Bluetooth Ethanol Content Analyzer (ECA) removes the guesswork from running mixed fuel blends. Popular upgrade for MHD Tuning tuned cars for example, allowing you to use all Flexfuel features MHD offers. It measures ethanol percentage and fuel temperature in real time, then sends that data to your ECU via CANbus for smarter fueling, timing and boost strategies. No more manual testing at the pump or constant “re-tune per tank” routines.

Ethanol sensor is not included, please see related products if you need to purchase the sensor kit as well.
