My Grand Rapids Technologies Engine Information System continuously updates
its screen while outputting all data once per second on a serial port. I just
finished my last test stand run of the SVX engine recording 2 EGTs ,
2CHTs,Manifold pressure,system voltage ,fuel flow,Rpm, engine hours,fuel
remaining,oil and water temp and fuel pressure. I use a laptop to store the
data during the run and Excel to graph the data for analisys.
