Ecumaster EMU Black ECU & K20A2 Adaptor Kit

Ecumaster EMU Black ECU & K20A2 Adaptor Kit

Take total control of your Honda Civic Type R EP3 or Acura RSX with the Ecumaster EMU Black & K20A2 Adaptor Kit. This comprehensive standalone management package is designed specifically for the K20A2 and K20A3 (manual transmission) engines. By combining the class-leading EMU Black with a precision-engineered Plug & Play (PnP) interconnector, you can bypass the restrictive factory ECU and unlock motorsport-grade features without cutting, splicing, or pinning a single wire in your OEM loom.

The K20A2 platform is world-renowned for its high-RPM stability and i-VTEC system. This kit provides native, high-resolution control over both the VTEC solenoid and the VTC (Variable Timing Control) cam phasing, ensuring you maximise torque and top-end power. Whether you are performing a K-Swap or optimizing a track-focused EP3, this kit is the ultimate foundation for high-performance tuning.

Technical Authority & Key Features

• Full i-VTEC & VTC Control: Precise, closed-loop management of Honda’s variable valve lift and timing systems for an aggressive powerband and optimised throttle response.

• Direct OEM Harness Integration: The included adapter allows the EMU Black to communicate directly with all factory sensors, including the crankshaft and camshaft triggers, injectors, and coils.

• Built-in Wideband Lambda: Direct support for Bosch LSU 4.9 sensors via an internal controller. This kit typically includes a pre-wired DTM connector for immediate wideband integration.

• Drive-by-Wire (DBW) Support: Integrated H-Bridges allow for native control of electronic throttle bodies, supporting advanced strategies like auto-blip and traction control.

• Intelligent Knock Sensing: High-fidelity, ignition-event-driven knock detection with 3rd order acoustic filters to safeguard your K-Series under high load.

• Internal 4-Bar MAP Sensor: Eliminates the need for external boost sensors, supporting forced induction builds up to 43 PSI (3.0 bar of boost).

• Swap-Friendly Design: Specifically optimised for K20 engine swaps into other chassis, providing easy access for auxiliary inputs like A/C requests or oil pressure sensors.

Technical Specifications

Installation Note: The A/C circuit does not always route through the base adapter for swap applications; however, the vehicle's A/C switch can be easily assigned to an available Analog Input for idle-up control.
