I'm a little bit annoyed about its intelligence!!

It doesn't recognize if the PC is on or not.
That means, when the PC is on before I start the ignition, the M2 shuts down the PC
Or if I prevent the shut down after switching of the ignition (with Streeddeck), the M2 thinks the PC is off, turns the amps of and also shut down, if I switch the ignition on again - that's shaming!

Shouldn't it be easy for the M2 to check the on/off status of the PC by the "power on" line (pin 14) of the ATX connector?? and react appropriate...??

If it responded adequate I wouldn't need an additional power switch (ON-AUTO-OFF) like somebody have.

What are your thoughts??

I don't have that problem. How old are your M2's? Maybe a firmare upgrade for it is in order? I can turn the PC on/off manually whenever I want and the M2 does grab the on state from pin 14. So if it is off when the car shuts off, it stays off. Then when the car goes on, it comes back on. If it is on when the car goes off, it shuts it off.

Seems like something is actually wrong with the M2, or maybe that is just using an older version of the PIC software, so it is not as intelligent as the new ones!

You need that for any "intelligence" at all for the M2. Without it, it is in dumb mode.

I tested it all again, and it seems that I was a little overhasty.

When I turn the pc off while ignition is on, and then also turn ignition off -nothing happens, so everything works right in this case!
But following situation doesn't work right:

- PC and ignition is on
- I turn the ignition off
- Streetdeck countdown appears
- I cancel the countdown and keep the pc alive

Now the M2 is irritated and thinks the pc is off and swithes the amps off.
Then when I switch the ignition on again it doesn't recognize that the pc is still running, sends the pulse and the pc wants to shut down.

I think the M2 is not prepared for a software like SD, where you can prevent the shut down.

But the most important is that I can switch off the pc while driving and it stays off when I kill the engine.

Does anybody have the same issues???

cheers, Roland

The SD shutdown thing is only if you are using the streetdeck prebuilt computers. It will not work no matter what on an ordinary SDC.

So does this mean that the M2 ATX isn't stupid and the thread need renaming?

It seems (I haven't tested this way) that following works right:

ign and pc off
pc on
ign on -> pc stays on

but not:

ign and pc on
ign off and pc prevented to shut down
ign on -> pc shuts down

It's not that bad, because I can prevent the shut down a second time.
A small blemish.

I don't want to have an extra "on-auto-off" switch.
All controlled with ignition.
But I want to be able to say the pc to stay alive after ign off.
But if I do so the M2 turn off the amps, so I have to control the amps with the 12V from the PC. Hopefully this works satisfying.

Also I managed it to crash the M2 with this procedure on time and had to disconnect it from power.

Aaaaaaaarg!!!! You CANNOT "PREVENT THE COMPUTER FROM SHUTTING DOWN". This is for the proprietary SD hardware. Your issue is with your bloated software, not with the M2. There is no way to prevent the shutdown and expect the M2 to know that because it sends it pulse like it should and assumes the PC is off. Then it waits until the hardoff timer is triggered and pulls the plug. If you want this functionality buy a G4 when it comes out...
