Post-swap questions

My D15B7-to-D16Z6 swap (fairly recently discussed in this group) has proven worthwhile, as the car is still going strong with only minor issues.
What I have now is:
93 Civic CX -> Original AT -> Original ECU -> D16Z6 engine.
Since the original engine was the D15B7, I presume that the ECU is a P06.
It's a given that the existing wiring harness has no provision for the VTEC capabilities of the Z6 engine. The P06 also doesn't have a clue about the VTEC.
I would very much like to get the VTEC going, to some degree.
1. Considering that this is a non-racing (ricing?) car, and the intention is to get *some* performance gain - would the most reasonable means of achieving VTEC be replacing the ECU with the one intended for the Z6 engine (which I believe is the P28)?
2. Does the Buddy Club V-CON (cheap controller) provide VTEC control when paired with a non-VTEC ECU? Many of the articles describe this device as being able to 'modify the profile', implying that a profile (i.e. VTEC capabilities) must exist as a prerequisite.
I don't want to spend hundreds on a more 'advanced' controller that most likely wouldn't give any sort of tangible gain for me. (I don't mind spending more to get an OEM ECU, of course)

don't presume, check.

it's best to replace the ecu - it's mapped for that engine.

it simply means picking the rpm's at which it switches.

spending money on a controller if you don't have a sufficiently well mapped ecu seems pointless to me. the b7 head is only 8 valves iirc, and that's WEAK. i'd get the correct ecu. it'd take care of everything.
