This new rear mount ethanol sensor kit conveniently installs above the fuel pump, under the rear seat, providing ethanol mixture and low fuel pressure readings via CANbus to your ECU. It's compatible with both flash only tunes and JB4 tuning systems. Includes our new CANflex ethanol content analyzer (ECA) using the standard 0xEC CANbus ethanol format. Low fuel pressure is transmitted in the 3rd byte.  

For those running a JB4 the new low fuel pressure signal provides an additional safety map trigger. And for those running port injection low fuel pressure can also be incorporated into your port injection mapping ensuring consistent performance even in situations where low fuel pressure is dropping.

For flash only cars your tuner will finally be able to monitor your low fuel pressure to determine if there is sufficient pressure for your tuning needs. Compatible with JB4, MHD, BM3, and all tuning systems that use the standardized 0xEC CANbus ethanol format. We can also customize the CANbus commands if needed, just email us the details.

The kit features heavy-duty stainless braided fuel line, Burger Motorsports CNC machined fittings, and unlike other similar looking kits was designed to minimize restrictive bends and maximize fuel flow.
