In essence using resistors is a bodge, you get none of the benefits of low impedance injectors and need to buy and fit expensive(ish) resistors. The range of easily available and large high z injectors is pretty extensive. I might think of using low impedance injectors if I had an application which needed injectors over 1000cc/min....

The correct method as chip says to use low impedance injectors with MS is to use a peak and hold driver board.

Megasquirt can actually drive low impedance injectors directly, you will need to use 2 more injector drivers though, each transistor is man enough for one low z injector or 4 high impedance injectors.
