The Link G4X HondaLink AP1 ECU is a plug-in standalone ECU designed specifically for the Honda S2000 AP1 (1999–2004) and AP2 (2005) models with factory cable throttle. It fits inside the OEM ECU enclosure and connects directly to the stock wiring harness. No wiring modification is required, making installation fast and straightforward.
This G4X ECU delivers advanced tuning and engine management capabilities while retaining support for most factory features. Built for manual transmission cars only, it provides tuners with precise control over ignition, fuel, boost, and cam timing — ideal for both street and motorsport builds.
Note: This ECU does not support factory E-throttle models. Before purchase, please confirm that your ECU connector matches the product image. Manual transmission only.
CAN Connector Update: 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 for connecting CAN devices. This port also provides 12V power and ground with a 3A self-resetting fuse.
