Link ECU Honda Civic DX LX HX 2001-2005 D17A1 D17A2 D17A3 Link G4X PlugIn ECU

The Link G4X Honda K20X Plug-In ECU gives you modern standalone engine management while retaining the convenience of a genuine plug-in ECU.

Designed for a range of Honda and Acura K20, D17 and K24 applications, the K20X fits directly into the factory ECU location using the original mounting points, wiring loom and ECU connectors.

No replacement engine loom or adaptor harness is required. The ECU is designed to work with the factory wiring while retaining supported original vehicle functions and maintaining a clean, factory-style installation.

A startup map is included to help get the engine running ready for final setup and calibration.

The K20X uses the same processor, firmware and PCLink software as the rest of the Link G4X range and includes the standard G4X feature set.
