The Link G4X HondaLink K20 ECU is a plug-in standalone ECU designed for Honda and Acura platforms equipped with the K20A, K20A2, K20A3, D17A, or K24A1 engines. This ECU fits directly into the OEM enclosure and connects to the factory wiring harness with no modification required. Built on Link's G4X platform, it delivers precision engine control for street, race, and high-performance applications.
This ECU is designed for manual transmission only vehicles and includes a built-in 7 Bar MAP sensor. It supports most factory features and expands the engine’s potential with advanced tuning options and full control of fuel, ignition, boost, and cam timing.
Note: This ECU includes a new 4-pin powered CAN connector. It is not compatible with the older CANPCB cable. Use the CANJST4 (Code 101-0198) cable to connect CAN devices. This port also supplies 12V power and ground through a 3A self-resetting fuse.
Please ensure your ECU connector matches the product photo before purchasing.
