I just picked up a set of RC550 injectors that were advertised as high impedence, which is what i'm 99% sure is what i need as i will be running MSPNP. The injectors just arrived, and are in fact low impedence (tested them myself at 2.6 ohms.)
I have an option of sending them back, or i suppose i could try to make them work with resistors. What exactly is involved in going the resistor route? Where are the resistors installed, and which resistors do i need? Would i be better off buying high impedence injectors. I paid quite a bit for the injectors, primarily because i thought they were high impedence.

Thanks for your advice.

Just Use a honda resistor box, easily found in junkyards and oe reliability. wiring is simple 1 yellow wire is 12v in, and 4 black goes to each injector 12v.

I've read (on MT) that using low impedence injectors with resistors makes for slower response time than using standard saturated injectors. Not sure if that's true. My main annoyance is i paid more to get what i could have gotten for less.

I'm running Low Imp RC750s now. I was using a Honda Resistor Box with no issues but now run a Peak and Hold injector driver instead on the same injectors.

So send them back and get the ones you paid for? That makes the most sense to me...
