GREAT info and pics Rog, thanks for posting.
I kinda threw in the towel when things went digital in matters automotive having had more than my fare share of issues relative to manufacturers wishes to maintain a degree of control over the kit you bought and by which ever means possible, much as they did in the past by introducing "special tool" requirement in the early days of Allen keys or Torx bits Posidrive etc which at the time were not part of the tool kit of the average would-be home mechanic. I guess with the arrival of digitisation manufacturers thought all their birthdays had come at the one time..given how simple it is/was to utilise digital means to inhibit access.
I think for some time now it may be possible to fit an after-market ECU to vehicles as a replacement for the original, and part of the package available is that it comes with a basic programme to run the engine which can be modified via your laptop or perhaps your mobile phone to more suit your ideals, perhaps even play you a tune....?

Trying to get back on topic, as a confirmed Luddite.. (-: I think it is just great that there are ever those determined not to be excluded and take the time to overcome issues. I guess the other side of the coin is that crooks are just as skilled, perhaps more so, given it seems unless you keep your car keys in a tin box overnight, they can seemingly clone your key from outside your house and use the clone to then steal your car...Hi-tec hot wiring perhaps..!
