Does anybody use low impedance (peak and hold) side-feed injectors in their OEM primary rails for a Cosmo (or any other) engine? I currently have the OEM 550cc high impedance primaries, with 1680cc low impedance secondaries, and I'd like to convert to low impedance in the primaries.

why?

I'm running an M2R and it can only select all high impedance or all low impedance injectors. My secondaries are low impedance, so I think it would be better to match impedances with low impedance primaries, too. I also hear the low impedance injectors are better suited for maintaining stable idle.

Elwood, what secondaries are you running? If you are running bosch 1600's, you can run them saturated as the motec injector drivers can handle it and then will be able to keep the high impedance primaries. Also, you were misinformed about low imp. injectors being better suited for stable idle..

PM me if you have any injector/motec questions.

Thanks for the advice. PM'd you.
