You could try asking td-d over at romraider for the code patches. But you also going to need to dissassemle rhe rom code to find where to hook it in and any other parameters you want to read or adjust, not a simple task.

No one has the source for the actual ecu code

The ecutek lc and ffs is definitly better especially the ffs, as it not just a single rpm limit it a variable rpm reduction based on your current rpm when clutch depressed and you can also alter the amount of ignition retard and the afr target and the resume delay
I'm a firmware engineer and entirely aware of what I'm signing up for. I get a sick satisfaction from doing things the torturous way.

Did the OFT guys get the patch from someone with an open source license or did they develop it themselves? If the latter, that's their bit of IP; I wouldn't feel ok reverse engineering it unless they have an open source license for it.
