Yeah, the chips are just a pair of EEPROMS - so if the chips are removed, and you have the correct EEPROM programmer then you should be able to read/program etc the chips.
That would then just give you a hex dump of what's programmed into the chips... figuring out how it relates to a fuel map, and which values to change is the bit that the tuning specialists would know. Hence it's easier for them to send a couple of pre-programmed chips that are just swapped out. Some EEPROMs can be finnicky to program aswell, and it's a bit more involved than what most 'home users' would want to be doing, so the plug-and-play solution is by far the easiest!

That was my understanding but maybe it can be done with UV light.

There was a guy on the Omega Owners forum who did a really good write up on them. He used to do all sorts. Cannot remember his name but I think he was polish. Thikk his username was something like prj and he had his own tuning business.

I will leave that to those who have clean hands after a full days work. I only understand things that are oily.
