The EVP Diagnostic Port replicator allows additional accessories to plug into the OEM BRP diagnostic port. Devices can share the port at the same time. Our daisy chain harness plugs into the OEM port and gives you 3 extra ports to use.
The port replicator also solves the issue of Maptuner X remaining on after the vehicle is shut off. Maptuner will only remain on for as long as the lights stay on. Once the vehicle powers down completely, Maptuner X will also power down.
