If we were really clever we could build an engine simulator
into the plug in PC board we are talking about to break out
Tracy's computer system wiring to better connectors.

For crude injector pulse width display you could use four LED bar
graph arrays. They are getting quite sophisticated now  a days.

Crank Angle sensor is a single chip oscillator.

Small pot for changing simulated RPM. Small
3 digit seven segment LED and counter for simulated
RPM indication. Will double as a small tach when
the engine is running.

Thats it. You unplug the vacuum hose from the engine
and plug it into Tracy's pressure sensor.
Pump it to the intake manifold pressure of interest and
program the pulse width at each selected RPM.

Did I miss anything? What do you think... all you EE types
out there?

I would buy one in a heart beat. Could save hours of
tuning time in the air or on the dyno.

Just take notes on what needs to be changed when flying
around or on dyno runs.
