 Black Plug-in ECU for the Volkswagen/Audi 1.8T BAM, ARX, ARY, AUM, AUQ engine code allows for plug and play installation.

What's in the box

  • Volkswagen/Audi 1.8T BAM, ARX, ARY, AUM, AUQ EMU Black plug-in ECU
  • 3 bar MAP Sensor with connector and terminals
  • Auxiliary Connector with plug and terminals

Note: There were many different 1.8T engine codes available over the years, we are not able to confirm functionality of engine codes that are not listed. 

    The EMU features more built-in value than any other aftermarket ECU. It easily matches the functionality of other stand-alone management systems with advanced VE fueling strategies and multiple inputs and outputs. Unlike many other ECU systems, EMU has built-in wideband lambda input (Bosch LSU 4.2, and LSU 4.9 sensors wire directly in), MAP control connector (4 bar MAP internal MAP sensor), 2 EGT probe inputs and an input to directly connect a Flex Fuel ethanol content sensor. All of this provides greater flexibility, reduces costs and negates the requirement for external or supplementary signal conditioning control systems and the associated wiring that other management systems require.
