7727 & Low Impedance Injectors

[dave w]

Thanks for the response everyone. There will be 8 of them and they're on a 2006 5.3 LS motor. I will have to test them. If needed, does anyone know the part no. for the injector driver?

Thanks again!

Don't forget the Injectors (Impedance) for the 1227727 ECM are in Parallel. http://www.1728.org/resistrs.htm

So one bank of four (high impedance) injectors, that individually measure 16 ohms each would = 4 ohms of resistance to the injector driver. If one bank of four (low impedance) injectors, that individually measure 1.6 ohms each would = 0.4 ohms of resistance to the injector driver. So I'm thinking with my example of four low impedance injectors measuring 1.6 ohms in parallel, the inline resistor of 3.6 ohms (25 Watts) is needed for the 1227727 injector driver.

There is the option of using two stock injector drivers soldered in parallel to divide the current path. Big heat sinks are good things to have on injector drivers!
