S58 FLEX FUEL ECA KIT

Dorch Engineering S58 Flex Fuel ECA Kit – True CANbus Plug & Play Ethanol Solution

For BMW G80 M3, G82 M4, G87 M2

Now that S58 tuning software supports true CAN-based Flex Fuel tuning, Dorch Engineering proudly offers a complete plug-and-play ethanol content analyzer (ECA) kit — purpose-built for full DME integration without the hassle of Bluetooth sensors.

With CANbus, your DME (engine computer) can actively monitor ethanol content and dynamically adjust tuning — from a full E85 power map down to pump gas and everything in between — on the fly. No more manual calculations, guesswork, or flashing between maps!
