i want to discuss FLYBACK.. i have a newer 3.6 ecu with 30v flyback that as the ts diode in it..
for flyback i just use a wire with no external diode. Right now i only have my injectors connected to the flyback Pin 23.
I have a 4 cyl but my flyback is connected like this... AFTER THE FUSE...

my Question is.. What all needs flyback? just devices using inj outputs? i want to hook up my boost selonoid soon, i wired it, but i want to use flyback.. can i just use a simple flyback with a diode from +12 to the vems wire right at the plug for the selonoid?
no other flyback is need except for inj outputs? correct?
i found this picture for an iac valve with diode.. is this ok for the boost selonoid from webshop?

Hi,
I wired my boost solenoid without external flyback using the EC36 pin24 high current igbt out,and it work fine.
For info it was an assembled ecu ordered.

you need that diode only for PWM type solenoid like IAC.
Boost solenoids are just ON-OFF.
thanks
