90 Integra LS w/ auto v-tec head swap??

[HondaIntegraXSI]

I am wanting to buy myself a US spec '90 Integra LS, but it is an automatic.. I have to use the JDM PW0 or PR3 pre-obd ecu's w/ v-tec for an automatic transmission. My hope has ran out for finding one of the ultra-rare ECU's and I was curious if an apex unit could control all then v-tec functions the ECU would normally take care of, like the V-tec crossover, the knock sensor, ect.. I will be doing the swap myself, so would the Apex unit be easy to install?? If this unit will control it, then what Apex unit should I look at?? Any help would be greatly appriciated!!!
