Electronics International CGR-30P Basic Upgrade Package 4 or 6 Cylinder

The Main Screen displays the Tachometer and Fuel Flow in large analog arcs at the top of the instrument, providing immediate and quick reference values. The digital display provides accuracy in monitoring engine functions.

The CGR Main Screen also features a complete, primary replacement EGT/CHT Bar Graph Engine Analyzer. Each cylinder is monitored by the CGR. If any EGT or CHT temperature rises above or below programmed limits, the CGR provides an immediate alert. The EGT/CHT Bar Graph Analyzer features both Lean-of-Peak and Rich-of-Peak Modes for easy engine leaning. The CGR-30P will let you know as each cylinder peaks, at what temperature each cylinder peaks, and how far below Peak Temperature each cylinder is operating.

To the right of the EGT/CHT Bar Graph Analyzer, the CGR-30P displays Fuel Remaining, Volts, and OAT.

The Secondary Screen is intended to display functions which do not need to be displayed continuously.
