Hello,
I have a CSR 260 and just changed to an SBD MBE 9A4 ECU. it is faster than the original, and it comes with a baseline map for the Cosworth 260 - or 200, I presume. I had a new map generated by Steve Greenald on the rolling road at Track and Road, over by the Dartford tunnel. I took this course since the original was very edgy at part throttle and difficult to drive around town - but the new map is quite fluid and the engine response is better all round. And I can use the EasyMap sofeater to tinker with it.. highly recommended.

Generally the route to a programmable ECU would be as above. You buy a replacement MBE ECU from SBD (that will be supplied with an open base map of your choice) and you construct a full map on the rolling road. The Caterham ECU's are locked and encrypted and generally impossible to use as an open map. But rumor has it that there are some Caterham authorised individuals that access the full maps - whether they can leave them open for DIY use is another matter. IMHO, you're best to start with a new ECU and keep the old ECU for when you sell the car (in original spec).
