Thu, 16 October 2003 23:10 In simple terms, impedance is AC resistance - just because something has a DC resistance of, say, 8 ohms at DC (0 Hz) doesn't mean it will have an impedance of 8 ohms at, say, 20 KHz (using a speaker as an example). Just like a speaker, inductor, transformer, etc. an injector is just a coil of wire. If you can't quite get your head around it, don't worry - main thing is that the bigger injectors get, the more high impedance ones SUCK - but low impedance ones put a lot more load on the output transistors of your ECU - so you have to find the balance (or buy a bloody MOTEC and use the lowest impedance injectors you can find ) [Report message to a moderator]
