I was trying/testing idle-channel output using two different channels.
Useing Step A "output" was always on (0% TSP of course) even before I started trigger-signal..
Useing SPECFET1 I never got any output (with config ... mcd dump ?), and it is mounted. Beware that flyback diode is needed for specfet when driving inductive load like a solenoid ! Connect a diode (like 1n4007 or BY399 or ES2J or similar)
- anode to switched point of the solenoid (channel output, EC18-pin..)
- cathode (marked with a line) to the other pad of the solenoid: the same where you connect the positive +12V (switched and fused) power
Q: What output channel is recommend fore idle-valve (2-pin VDO-valve)?
- a free injector channel is most common
- or a stepper output
