DPFI to MPFI 91 STD Hatch thinking of converting to MPFI I have a MPFI 1990 HF intake manifold complete with 1990 HF ECU

will the HF ECU and intake manifold and injectors etc work properly once wiring is done or will I need the Civic Si intake manifold and ECU?

woah woah woah...

What is wrong with using the HF multi point setup for this swap? It wouldn't do much for power, but it should get great gas mileage.
