Dorch Engineering – CAN Flex Fuel Kit (S58)

Now that S58 tuning software supports true CAN-based Flex Fuel control, we're offering our own plug & play ECA solution!

With the use of CAN, separate Bluetooth ethanol sensors are no longer needed. CAN-based ethanol readings not only monitor the ethanol content of your fuel, but also communicate directly with the DME to allow for full Flex Fuel operation.

With Flex Fuel programming, the DME automatically adjusts the tune in real-time, depending on the ethanol content of the fuel you're running – all the way from an E85 map to a standard gasoline map and everything in between. All done on the fly through the CAN bus, no manual map changes or blend calculations when fueling up.

Completely Plug & Play – No Wire Cutting or Splicing!

Installation is fully reversible, with no modification needed to the car's original harness. The wiring tucks away cleanly into the OEM system, and all original engine aesthetic foams and covers can be reinstalled.

The ethanol sensor is placed as close to the fuel injectors as possible, ensuring virtually zero lag in ethanol content readings and optimal engine response.

Don't let the detailed and DIY-friendly instructions fool you – the kit is easy to install and will take about an hour depending on skill level.
