There's also an Arduino based version somewhere, but I've lost the link

I think that might do what I need

That's the one.

My power supply arrived in the post today!

I just need to finish making my comms cable tonight, then I can hopefully get access to my ECU, which is exciting!

I've crudely pinned some wires with small pliers and a bit of solder, figured this would be OK for a bench loom.

Anyway, I've pinned 13 and 14, they'll go to ground, then 31 to positive. Looking at the wiring diagram that's all I'll need?

Yup, that's all that's needed

Tentatively connected everything up, and it seems to work.

Was able to load a map or two onto the ECU. One thing I noticed was the elise map that ships with the software pulled about 1.7amps whereas the zetec map only .3amps.

I went to turn on canbus, but noticed that frequencies were greyed out?

The Elise uses amplified coils. This is normal, as the ECU drains the current generated by the coil drivers.
Make sure to never connect an ECU with amplified coils ticked to unamplified/dumb coils. You will blow the coil drivers.

Your ECU is firmware version 52, so that option won't be available until you update the ECU.

Successfully updated the firmware this evening, and managed to get a bit of CAN BUS data too.

I think I've fallen foul to cheapy Chinese knock-offs as I'm only getting the very first message repeating over and over, rather than 2000, 2001, 2002, etc.

I've got a legit transceiver coming in the next couple of days, hopefully that solves my problem.

As suspected, the cheapy Transceiver(s) I've been trying to use are to blame.

I have a full collection of CAN data blocks to read now, next stop output to 5" display.

keep us posted..
5" display sounds good.
