Do I need?

my 89 Dx civic hatch... If i'm switchin from the old dpfi system to a d16z6 head/manifold/distrib etc mpfi setup... and I DO have the Vtec computer....out of a 93 EX i believe.. Do I still need an injector resistor box? I know the old system is low impedance, and vtec injectors are high impedance but since i'm switching the computers over to match, wouldnt that just make me a high impedance system and not even need the injector resistor box? Thanks for any help :|

Anyone know?

well, "I have heard" that if you switch to obd1 you dont need a resister box, but if you stay obdo you have to you the resister box

if your using the obd1 (high impendece) injectors you do not need the resistor box. if you use the oobd0 (low impendence) injectors you will need to get a resistor box.
