Normally, sending units (sensors) for coolant temperature, fuel
pressure, and such are connected to analog gauges. Can anyone point me
to products/kits/thingamagigs that can be used to connect the sending
units to a computer, maybe via a USB interface. I want to collect and
analyze engine data over a period of time.

There are some products around.
You need an analog input measure card mostly resistance capability for
your computer and a software to display or/and record results.
Some measure cards are connected via USB or use a data logger.
A company for professional applications in this business is National
Instruments.
