I have an engine monitor from Audio Flight Avionics. Fits in a

single

standard instrument hole and has a single line LCD display. All

parameters

scroll through the display at a rate set by the user or the user can

set

the display to show any of the parameters wanted. High and low

limits

are

fully programmable and any time a parameter goes out of limits that
parameter pops up on the LCD and the monitor anounces via the
intercom/headset what parameter failed.

  My monitor handles:
RPM
MP
Coolant temp
Coolant pressure
Oil temp
Oil pressure
Fuel pressure
EGT (2)
Volts
Amps
Also has built in user programmable timers and Hobbs.
And has a remote 4 line x 40 character LCD that can be installed

wherever

is convenient.

  I paid $800 with all sensors a few years ago. Unfortunately Audio

Flight

Avionics is no longer in business. I thought it was a great bang for

the

buck unit.

I too intend to use this unit on a test stand. Nice piece, but I had to
wait a long time for it. Mine outputs RS232 on pins 24 and 25 (this is a
later version with 2 DB-25 connectors at the rear, via a level shift
convertor at 9600 baud).
Now, I also have an ipaq and run Controlvision's gps on it. I guess that
$99.00 software could enable a secondary display but why bother?
These outputs are mostly used for data logging to a pc.
Mike can you let me know how yours worked out and what you ran into
making it work?
Any way to contact the Canadian persons who built it now?
Seems a shame they gave up to the Grand Rapids people. Competition is
good, esp if from Canada!
