What makes the EIS the best automated engine monitor/analyzer available?

LARGE, sunlight-readable, backlit display is EASY to read. No games to play to figure out what is being displayed. No flickering displays. Simple, continuous readouts of all cylinders at one time. User-customizable pages.

Flexible Leaning Pages – Most instruments allow you to lean according to the technique the instrument designer had in mind - a necessary compromise due to the limited information provided on their small displays. The EIS uses a 32-character display, and 5 different pages of EGT data. This makes leaning your engine easy, no matter what your leaning technique.

Graphical and Digital Displays -- Not sure of your preference? Don’t worry. We give you both. Our graphical displays have better resolution than any of the big name monitors.

Cruise Monitor – Direct display of the EGT trends during the course of your flight. Digital and graphical. Dedicated alarms.

EIS Leaning Function - The EIS tells you which cylinders are past peak, which cylinder peaked first, and how far each cylinder is away from peak.

Value - Save fuel and increase range by leaning correctly. Reduce maintenance costs by detecting problems early, and diagnosing problems to the affected cylinder (or better) thanks the extensive monitoring and alerting provided by the EIS.

No-fear installation - Color coded cables with easy-to-understand wiring diagrams. All inputs are protected from damage due to wiring errors or aircraft electrical problems. If you find a way to damage it during installation, we will fix it at no charge.

Options :

Fuel Flow System – Provides flow rate, fuel remaining, and time until empty. Includes a FloScan Fuel Flow Sending Unit. Accurate to better than 1%.
