Speed limiter, both RPM and top speed would be easy for an experienced tuner once he gained access. Much less complicated than various ign / fuel tables- as those deal with feedback on air /oil sensors / rpm / throttle position / etc.
Getting into an ECO at all is getting very difficult.
In the early days- (90's) guys would have to open the ecu, take out the actual chip, put it into devices to tune it- and sometimes either re-solder to the boards or add a socket to plug it into.
In the early / mid 2000's- they could plug into OBD ports on many cars and get it to tune that way with nothing more than a laptop and a special cable.
But for roughly the last decade- they are back to having to remove the ecu's and 'bench flash' in various ways.
The differences are stark. My wife has a VW GLI- many shops have a tune for the same year GTI - but not for her car- the GLI and GTI have different ECU even though the engine is pretty much the same. I had to resort to a 'piggyback' on her car - to intercept and modify (trick) the stock ecu into changing what it sees and does (the power commander on our bikes is a piggyback).. but yea- a simple box plugged inline under her hood makes more power / boost on the turbo. Not as good as a real tune- but very easy, cheap, and effective and removable at a moments notice.
Watching this video- it is great- shows the complexity. He mentions thousands of maps...and that is on a motorcycle.
Modern cars have stability control, traction control, adaptive suspension, turbos... massive complications.
