High on the passenger side is the OBD port - an OBD2. Anyone got one like this and know how to connect this to the Speed 6 software ??

I don't think you can get that to work with any normal OBDII readers, as the ECU doesn't support the standard protocols. Almost all cars have the TVR / MBE 3-pin plug near the steering column which you use to connect to a laptop using the TVR or EvoOllie's software. Best to just use that connector.
It looks like the below:

(So white+green, white+red & black+white wires)
I think the same wires are there in the OBDII plug, as some have rewired to connect there when they can't find the 3-pin plug, but easiest to just use the 3-pin plug if it's present on your car.

The old MBE ECU uses the 3pin connector and use the old TVR Cerbera(Blue/Yellow) or EVOOLIS android s/w but if you have the new MBE ECU supplied now by TVR Power with anti knock sensors it uses the OBD plug on the passenger side and you new an OBD/USB dongle to use the new MBE s/w.

Hi Matt. I don’t have the 3 pin plug, this is the port so I suppose I need to find which wires to use and rig it up to a 3 pin one, or change it to 3 pin?

confused

Does anyone have the layout of which wires go where on a 3 pin plug?

Where could I get a 3 pin plug??

I have a spare diagnostic cable, maybe even the serial to USB adapter too. Drop me a PM if interested.
