The EIS

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. Press-to-see labels.

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. Our digital leaning page has proven to be one it the most popular function. Its shows when each cylinder has reached peak, and how far past peak it is with 1 degree resolution.

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. The digital data displayed with the graphical pages is user programmable.

Cruise Monitor – Digital and graphical display of the EGT trends. This function reveals which cylinder is causing your engine to run rough, or reassures you that all is well when setting out over hostile terrain. The costs savings in maintenance provided by this function easily justifies the cost of the entire instrument. More useful and important than the leaning function.

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. The leaning status of all cylinders is displayed simultaneously, making it simple to see how well balanced the mixture is to the engine.

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. This robust design is responsible for the outstanding reliability of the instrument, and is the reason  back it up with a lifetime warranty for the original owner.

EMI Tolerance -- The installation of the instrument, and its wiring is completely non-critical. Special routing of wires or other considerations are not necessary, as the instrument is able to tolerate any level of electromagnetic interference (EMI) present in an airplane. Emissions from the instrument are practically non-existent, so that it will not affect radios of other equipment.
