Mr Stronghold
You omit to say where you are?......I am tuning the fuel injection fitted to my plus2 (steep learning curve) and as the rest of the forum knows I'm not one to throw my money about (either that or i prefer messing around to see what I can do) .....Megasquirt is a self assembly kit (or you can purchase ready built/programmed) and as for the rest....crank sensor,fuel pressure regulator,high pressure pump,throttle bodies etc,etc,etc. can be picked up quite cheaply (fleabay,breakers yards etc.)
If you want I can post some piccies?
