Series 4 low to high Impedance Injector Conversion
 

Hi All,

I've done a little digging but have not come up with a simple answer on this.

What exactly needs to be done to the car to run high impedance injectors? Links to parts needed and pictures would be very helpful.

My car is an 87 Turbo II, I have not tested my current injectors but I believe they should be low impedance from the factory. If that is the case when I test the system and I want to run new Injector Dynamics injectors what needs to be changed?

Thank you,

you need to bypass the resistor pack and get injectors that either fit the connectors or wire the connectors to fit.
You also need to make sure that the injectors fit the rail properly and that the ECU can run them with the correct fuel amount.(if you are going aftermarket then you just need to tune the new ECU)

Thanks for the Info! At the time of getting new injectors I will be going with a standalone ECU, so fitment and ability to tune are no problem.

Do you know of a write up on how to bypass the resistor pack for proper installation?

Thanks,

If your going to a standalone ecu st the same time, you'll be re-wireing everything anyways so the resistor box is the least of your worries

That is very true! Didn't even think about that smh lol. So to conclude this thread, if I have the stand alone ECU to wire in and the new high impedance injectors that fit correctly to my stock rails I am good to go. Correct?

Thanks for the help guys, I appreciate it.

Correct because all ecu's see high impedance for injectors, and all new injectors are high impedance anyways, so when your going to be running new wiring direct to your new ecu, it doesn't matter

The low impedance injectors mazda used was just another one of those silly things manufactures do with cars
