I use USB over wifi for controlling my ECU remotely (my ECU is in the boot next to the engine so no long USB wires through the cabin).  I bought one of these from amazon which work great and are cheap :- https://www.gl-inet.com/products/gl-mt300n-v2/   The hardware then needs reflashing with the virtual USB software:- https://www.virtualhere.com/hardware Powered with a 12V to 5V micro USB adapter, this gives you USB over WiFi, which should be significantly longer range t
