Thanks everyone, that's all very helpful. I'm off to get a lead and prepare to waste many hours happily in the garage!

You will want to be out on the road Graham. Put the laptop in the passenger footwell and log the data. Typically you will find about 30 channels to capture, the files are manageable up to about 30 minutes of continuously logging, after that the subsequent display of data will be increasingly slow on an average Windows 10 machine.
Easimap works well in a virtual Windows environment, but if you do end up with an unlocked ECU and do load new maps, you need a very reliable Windows machine that won't fail during map load (I've been there with my unlocked ECU, had the laptop hang during map load, had to send the ECU from Canada back to SBD in the UK to have a reflash for 1 hour of labour plus express courier charges). My general purpose analysis PC is a Linux Fedora 33 box with Easimap running in a virtual Windows 10 machine, my garage laptop runs Easimap natively on Windows 10.
Oh, cracking site, Oily. Thanks.
like OilyHands, I have some articles on my website looking at the protocols used by the MBE ECUs. There's probably way too much information there but I mention it in case you're that way inclined.
There was also an article written about our findings in the June and July editions of Low Flying in 2020.
You can find my ramblings here:
Caterham 420R SV, lowered floors and some creature comforts.

This Club really has a plethora of information.
Wow! That is a lot of info John! Many thanks indeed. Given that DVLA tell me to expect a long wait for my V5 following their strike action I suspect I will have to delve into all of this to keep me from going mad whilst I wait. My IVA passed on 30th March and at this rate it'll probably be early June when I get to drive the car.
Whilst writing, many thanks also for your terrific blog which is one of 3 that I used really extensively when building the car. It sure made it a lot easier.
Good luck with the registration docs Graham. It was an interminable wait for me over Christmas.
And thanks for taking the time to tell me about the blog. It seems an age since I did it and I'm glad its still useful.
The MBE ECU on the 310R is a locked MBE and not a 9A4 variant as fitted on the fixed Cam Sigmas. Downloading the software and the obtaining the communication lead will only allow you to view and not modify anything.....which from a suppliers point of view is a good thing.
If it isn't broke,,,,,don't fix it, if you know what I mean.
