Plug-In Engine Management

Link PlugIn ECUs totally replace the original factory ECU, in the original location. Fast install, full engine management, tuning solution!

Link Plug-In ECUs provide a straight forward way to gain full control over your engine functions, whilst still keeping the stock appearance & wiring of the car’s original engine control unit.

Where possible, the factory enclosure is reused and a replacement board is supplied which the installer swaps for the original factory board inside the original enclosure. Where this is not possible due to the design of the factory ECU, the Link ECU is supplied in a full or partial replacement enclosure.
