And no fault codes?

Vtec solenoid perhaps? Complete guess.

at first i thought it wasnt but there is a very slight change in engine tone.but nothing like the usual switch over.

So the question is what are the ECU inputs required to activate Vtec...

Road speed - sorted
Oil pressure - ???
Throttle position - ???

There's more I'm sure...
