Alternative Views:

  • G Series is best technology available, there’s nothing else like it, nothing even comes close.
  • Operation lean of peak requires special information that only the G3 or G4 Graphic Engine Monitor can provide.
  • The G Series instruments are extraordinarily capable yet easy to use.
  • G Series specialized innovative leaning process is the first and only one to ever earn a patent.
  • Unprecedented in its sophistication, most importantly it makes a complex process easy to accomplish.
  • Leaning with reference to temperature only is just too confusing for LOP.
  • Our specialized process reports each individual cylinders status in unambiguous form.
  • You needn’t ponder if a cylinder is rich or lean we display that too.
Injector Analysis:
  • Nozzle flow uniformity is paramount to operation lean of peak but only Insight delivers a nozzle analysis every time you lean.
  • G Series can forewarn of problems and assure uniformity of results. Of course other systems just leave you in the dark.
G Series Data:
  • G Series instruments are not just temperature indicators, they compute real-time results using manifold pressure, RPM, fuel flow and temperatures.
  • G Series handles the raw data to eliminate confusion and provide answers. It couldn’t be easier.
  • While constantly displaying critical information during flight the G Series always work diligently behind the scenes too, logging data to a handy SD card for study later so nothing is missed.
  • It’s easy to go back in time, study trends and trace problems to root cause
  • Decades ago Insight introduced the first instrument to display cylinder and exhaust gas temperature of all cylinders simultaneously.
  • This innovation eventually became the industry standard as all other manufacturers followed suit.
  • Engine monitors depend on numerous temperature probes that have equal potential to inform or confuse when any of them fail.
  • In fact probe failures can easily be confused with engine failures.
  • Only the G Series has a probe diagnostic system built in.
