Does anyone know if D15/16 injectors are high or low impedance? A reference by engine type would be great like D, B, H, F, K series.

If we are using a low impedance injector (3 OHMS) on a D15B7, I think we will need to add resistors to bring the impedance to ~10 OHMS. Thoughts?

The F Series engine, Accord, uses a resistor box to convert. You can use this to convert to low impedance. Thats what the honda guys do when they use DSM high imp injectors in a B series motor. You can also make your own from resistors from radio shack but picking up a resistor box is cheap and easy.

So are stock D series injectors low impedance?

Thanks!

I'm pretty sure. Not 100 percent, but pretty sure.

unplug the injector and ohm it out

Wrong. You cant convert from high to low impedence. Only from low to high. EX; you can run 3 ohm injectors in a car that requires 12 ohm injectors, but you need a resistor box. You cant run high impedence injectors and convert them to low.

And its hard to tell what injectors were used in what year Honda's. Early 90's they started to switch it up a bit. If the car has a resistor pack (looks like a heat sink with wires coming out of it, then they used low impedence injectors from the factory.
