Oy, this was no plug and play task. The OBDI Nissan consult port is entirely different from the interface I had to fabricate, which was a 14 pin connector on one end that connects to the laptop via USB on the other. The Nissan consult plug wiring colors also don't stay consistent from the ECU to the original Nissan consult, at least on my car anyway, so I had to figure out on the ECU end what wires were sending data for CLK, (Tx)Transmit, (Rx) Receive. It was painful. The wires coming off the ecu is a plate of spaghetti that doesn't go down easy! The closest thing to this really for a VE is a $2199 piggyback unit AEM makes. I had a daughterboard fitted to my ECU by NIStune that allows for on the fly programming and can be loaded with maps at will, as opposed to ECU's found by the likes of JWT that are programmed once and you're stuck with the configuration you buy.
Had to make a little celebration video for it -- it's ALIVE!
