Whats ECA? CAN Ethanol Content Analyzer reads information from E85 Sensor, converts it to CAN format, and sends it to Engine Computer (DME). What's the Difference between E85 and Flexfuel? Shortly, E85 - is a type of fuel, that has very high octane rating. FlexFuel Feature - The ability to adjust the Engine Computer parameters on the fly,or in other words - autotune - based on information from ECA, Frankly based on the E85 content in the tank. What is this Kit? This kit enables a FlexFuel feature for MHD and EcuTek tuned cars. Without the correct tune (for the E85 blend used), the engine will not work right and may get damaged. Which cars are supported? G20 - B48 or B58 Supra MKV - B48 or B58 G30 (5 Series) - B48 or B58 G32 (6 Series) - B48 or B58 G01 (X3 Series) - B48 or B58 G05 (X5 Series) - B48 or B58 X3m - S58 X4m - S58 M3 G80 - S58 M4 G82 - S58 All F series B46/B48/B58/N55/S55 with Automatic Transmission or DCT Manual Transmission cars (B48/B58/N55/S55) N54 cars N55 E series What else do I need to know?
