My D15B7-to-D16Z6 swap (fairly recently discussed in this group) has
proven worthwhile, as the car is still going strong with only minor
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
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)
