say i have an ecu that's originally designed to run one pair of injectors. could the wiring to those injectors be branched off of to run a second pair without burning out the injector driver in the ecu? maybe the sum of the impedence of the 4 be the same as the sum of the pair, if that makes sence, to keep from damaging the injector driver?

I did that; just make sure that the total impedance is the same, before and after. My original setup had 13 Ohm injectors, and then I used two 3 Ohm injectors and a 7 Ohm resistor. Worked just fine. The computer just needs “to see” 13 Ohm, it doses not matter how many injectors or resistors there are.

so as long as all injectors have the same resistance, all will be fine?

Yes, the injectors will have to be low impedance

ok thanx. i must have stumped those on the rx7club board. have yet to get a response from anyone there and i posted it there at same time as here.

finally hooked some responses from the 7club:

unfortunately it's totally opposite from what i got here. was really hoping my idea would work.
