hi,

i'm looking at the hfs 3 diagram https://www.evolutionm.net/forums/8390215-post2.html for evo x specific..

i'm specifically looking at the ecu wiring, tapping to "injector (-)" pinout 18..my question is, the "injector (-)" input, what does that read for the hfs3 input? 0-5v?

thanks in advance!

 

The injector(-) signal is a PWM (pulse width modulation) signal.

 

^^ thanks for the reply as always
