Slight changes were made with every model. The VX had upgraded computer power from the VT for its more advanced fuel injection and ignition systems.
there where very small changes if any between vt11 and vy11, the egr valve from vt1 or vt11 was introduced and that was it, any computer from vt to vy will run a vt to vy engine, you could use a vs engine on a vt to vy engine but it wont like not having the egr solenoid and give fault codes, doctor bob on here will be able to help you out here with removing the anti theft from the computer
cheers glowworm your spot on my 3.8 vx motor arrived today and the plugs are different, looks like a got a spare vt manual pcm and im chasing a vx one, guess a manual vx pcm would be like finding rocking horse sh*t, oh well looks like it an auto one reprogrammed
