PDM30 ignition power & auto start

Postby whrdnsx on Tue Dec 30, 2025 1:34 pm

I've got M150, PDM30 & keypad.

I've got some things working albeit in a pretty basic configuration whilst I slowly get my head around setting it up.

I've got Ignition/Injector power on one keypad button & cranking/starter solenoid on another button.

ECU & C127 is powered up with Master switch on (it's a bare bones track car)

Is it possible for the cranking/starter button have 3 functions? for example, a simple one press to turn ignition power on or off and a press & hold for cranking (with ignition power on or off) & when the engine is running a press to turn the engine/ignition off?

I've attached my basic config in case.

any help is appreciated.

Hi,

Whilst this is possible, I wouldn't recommend it. I would have a dedicated button for the starter, and another for the ignition toggle on/off. Having them both on the same button can lead to issues where you are trying to start the engine but the ignition is getting toggled off at the same time.
