Does anybody know what os ford uses on the SDs pcm? Last night I was told it was QNX and thought it was cool. I can't find anything on it.

 

I thought ford used an inhouse os. QNX does not list ford under there customers.

 

In a nut shell that's what I thought. I don't put much faith in the fact that ford isn't listed as a qnx customer. Like the powerstroke name. Its Ford's but they have always built the engines.
I could see Ford keeping their name off a list.

 

I'm going to guess its proprietary. With complex systems its often easier to write a custom OS than make an existing one work for what you need.

 

If they still use the Motorola 68HC11 microcontroller, that wee beastie can use custom compiles of several programming languages, BASIC (the later forms) included.

Back in the dark ages (early '90's), when I looked at programming one, you wrote your program in (BASIC, FORTRAN, C) and ran it through a PC-based custom compiler and downloaded it to the controller.

As for QNX, last I knew, they used it not in the PCM's, but in the NAV and/or entertainment systems.

I think it's custom all the way. I could be wrong

 

There won't be an OS running, too much overhead. It will just be compiled machine code running on the controller.
