My question is about connecting devices to free INJGroup channels. I want to run 4 injectors, so I have 4 outputs free at the moment. I need to drive boost solenoid, 3-wire (dual coil) ICV and variable cam solenoid.
I have ordered assembled VEMS with integrated 30V flyback. As we know, flyback must be connected to +12V after the fuse for the injectors. But I was searching viki for information about connecting boost control solenoid and i read that
"electronic driving:
* using a free injector channel recommended:
Flyback is needed."
So my questions about that issue?
1) I guess I can't use already integrated 30V flyback that is in controller? It's only for injectors Vbatt+ ? So how should I wire-up second diode and make "second" flyback for those extra devices? How to connect it? (some diagram will be helpful)
2) Does other things connected to INJGroup such as variable cam solenoid or 3-wire ICV also needs flyback?
Sorry for my lame questions. I don't want to fry anything during first start up
