Any info on how the computer works ('95 t&c)

With the computer being all powerful under the hood, it would really help to
know how the darn thing works.

This came up in a previous topic ('95 T&C Mystery Engine Death) - the
question was - what conditions would cause the computer to activate the
AutoShutDown Relay?.

But my question here is - is there any free (detailed) info on how the
computer works? And failing that, is there any info for sale?

Still driving in 90+ weather with no AC so I dont suddently stop in the
middle of the highway.

 

I think the purpose is to shut off the fuel pump and fuel injection if
the engine stops turning. I think it uses the crankshaft/camshaft
position sensors to determine whether the engine is turning, and I
believe those are common problem areas.

Hopefully one of the true experts will jump in here... ;-)

How the computer "works" would fill several books, if you want the
detailed version. No two car companies make them exactly alike,
either. My son's older Mustangs has the computer program in a chip
that can be removed, replaced, or upgraded. Some of my recent
Chrysler products have the entire module filled with plastic Jell-O so
nothing can be removed. Upgrades/updates are done by updating an
EEPROM through the diagnostic cable. I know of nowhere you can find
or buy the detailed version.

The simple version is that the computer monitors everything with a
sensor in the engine and tranny, and then adjusts everything variable
in the engine and tranny for the best economy vs. power under the
existing conditions. It varies fuel/air ratio, ignition timing, etc.,
in the engine, and tells the transmission when to shift, based on
throttle position, engine load, etc.
