Should I connect any additional flyback with the following setup:
Inj (FET) A,B,C,D,E,F to fuel injectors
Inj (FET) G, H to ICV
12V+ to the ICV will be connected to the same source as the injectors:
IGN (IGBT) A,B,C to wasted spark coils
IGN (IGBT) D to fuelpump relay
IGN (IGBT) E to FAN relay
IGN (IGBT) F to boost solenoid
Switched 12V+ directly from the fusebox (thee different fuses: coils, fuel+fan, solenoid).
In the manual there is no flyback for the IGBT's pictured. However for the boost solenoid I found the advice to apply a flyback diode. Should I connect flybacks for these 12V+ feeds aswell, and if so should these also be connected to EC36p23?
To me it seems the flyback for the injectors also serves for a flyback for the other 12V+ feeds since these are all connected to the battery + in the end. But then rises the question why the flyback in the picture above is not in front of the fuse?
Ps. I assume a 1N4007 diode would do the job just fine? (I'll not connect this one since my vems unit has the diode internally).
