i was woundering if every type of injectors need a relay i read somewere that the hight impedance ones dont need one and the motor is obd0 just looking for some help and whats the difrence between saturated and peak hold wich ones are better

 

I think what you may be referring to is a resistor pack. Only low impedance injectors need to have a resistor pack wired with them. This effectively raises the resistance of a low impedance injector so you do not end up with a burned up injector driver inside the ecu, making the ecu a pile of scrap.

Most newer model injectors such as the injector dynamics injectors are high impedance which the computer can control with no problem. If you're using something to the tune of an S300, AEM, or similar computer the injector dynamic injectors come with all of the proper data so that the injectors will function and drive as smooth as a stock vehicle. You can visit the injector dynamics site for more detailed info, as well as, a list of dealers.

 

it sais that high impedance ones were used in 92-95 civics thats what i have but my motor is out of a 89 teg so im not sure what they are
