Injector wiring

Postby MTBGerman » Tue Oct 30, 2018 1:13 am


I have a Elite 550 with a Toyota 4AGE engine and OE Wiring harness.

my question is, can I use all 4 outputs for the injectors, to drive one low impedance injector? I have the problem that the 4 injectors wired in parallel and the resistance is about 0.58 ohm. I will use a adapter wiring harness, so I don´t modify the OE harness from the car.
Is it possible? Or must I use injector output 1 for all injectors with an resistor? The injectors have 0.58 ohm + 1.5 ohm is about 2 ohm
14V / 2.08 ohm is 6.73A so I can drive the paek/hold in 8/2 amps, correct?
I just wanted to know if it is possible to bundle the outputs?

It is not the way to do it. One driver per injector but in all honesty you should not be using injectors with 0.6ohms resistance. The resistor would normally be around 6 ohms in most ballast packs.

If it were me, I would swap the injectors for something far more modern with better spray patterns that do not draw so much current. You win with every aspect of control, reliability, power, smoothness, and economy.
