If you have a 96, VTC will be restored as soon as you install a 90-94 ECU or standalone. If you use a 90-94 ECU, they use different connectors so you will have to build a harness adaptor or splice in a pre-OBDII connector on your 96 harness. Every 96 I have seen had the VTC solenoids installed, they just sit there in one position with the 96 stock software.
This site tells you exactly what to do as well as selling tune chips that work on 96:

I think that this route is esier (and less $$$) than a standalone. Sure, controlling a standalone with your laptop is very cool.
