Default Best fuel management for OBD-2?

What is the best fuel setup for obd 2 cars? I am thinking about getting a 97 cx and putting the d16y8 in it which is all obd2 cause I like the body style and less miles on that motor. What would be the best route of fuel management with this. I wanna push about 5-7 psi on the streets safe as can be and about 8-9psi at the track once again safe. Would the best route be go hondadata with 450cc injectors. OR would it be V-afc, dsm turbo injectors, walbro fuel pump, msd btm? Does hondadata even sell for the obd-II? Thanks guys IF the turbo setups matters I am planning on going ihi rbh5 or else t25 with hf manifold sidemount intercooler and greddy bov.

nobody is gonna help me? I think it would be much easier to just buy the vafc, msd btm, fpr, fuel pump, injectors with an obd-II instead of trying to change the ecu and everything. Am I right?

So then the vafc, fuel pump, injectors, and msd btm is a good safe setup?

Does anyone know whether it is true that the secondary oxygen sensor effects air/fuel mixture during open loop?

If thats so thats the only thing you gotta watch out for with the OBD2 setup (as far as I know at least)

Just get the second O2 out and put a O2 simulator

Open loop has nothing to do with fuel efficiency, so the O2 sensors are ignored and the ECU operates purely off of the preset maps.

first of all, Hondata will only work on OBD1 ecu's only, so to go the Hondata route, you have a few option;
1) you can buy an obd1 p28 ecu from hondata that has obd2 plugs on it, and it plugs right in

2) buy an obd1 ecu, and buy a conversion harness (or buuild)
