abd al darweesh Posted April 6, 2011 Report Share Posted April 6, 2011 hi. Welcome to all of you . are you well. We are sorry for what happened to the country. I have a question if you don't may. Is there a difference between low impedance injectors and Peak and Hold. Because I have to wear them The question is, I have g4 Red Xtreme . Does it work well with peak and hold injectors or i have to use saturated injectors. Quote Link to comment Share on other sites More sharing options...
Simon Posted April 7, 2011 Report Share Posted April 7, 2011 We are all well. And very fortunate to be able to carry on mostly unaffected. Peak and hold is the term used to describe a control method when using low impedance injectors. So a peak and hold injector will be a low impedance injector. The G4 Xtreme (red version) can drive low impedance injectors (peak and hold) but you will need a ballast resistor pack to avoid damage to the ECU or injectors. Or if you wish to not use a resistor (ballast) pack then high impedance (saturated) injectors will be required. Quote Link to comment Share on other sites More sharing options...

Simon Posted April 7, 2011 Report Share Posted April 7, 2011 Assuming you are running conventional coils and not CDi ones there should be no reason to not use the factory Nissan igniter. Quote Link to comment Share on other sites More sharing options...
