So I am running an rTek 1.7 with 720cc secondaries and my car runs rich at idle and leans out under boost. Rtek told me that I might have my injectors reversed. However, I can see that my injectors are in the right spot, but I am not sure if I wired them wrong. Does anyone know if it is possible to wire them wrong? Or any ways find out?

 

You could on your series four car.......go to the ECU and pull the small plug off.

Then with your meter go to the front primary fuel injector wire in the PLUG. Key on you'll see batt voltage. Now while batt voltgage is on that front primary fuel injector wire, go to the engine bay and pull the fuel injector off the primary fuel injector. The result is the loss of batt pwer on the meter. Put the fuel injector plug back on and the voltage will now reappear on the meter........proving the front primary fuel injector elect plug is on the right fuel injector.

Then you could do the same for the other primary fuel injector by putting the meter on the rear primary wire in the small plug of the ECU............and then do the secondarys the same way.

Seeing as how the secondary plugs are batch fired there's no really good reason to do them other than making things stk. as far as wiring goes.

 

Thanks Hailers, you are good!

 

The color of the front primary is LIGHT GREEN.

The color of the rear primary is LIGHT GREEN with A BLACK STRIPE.
