EDVA puts your engine monitor data on screen in seconds — EGT trends, CHT monitoring, alarm detection, and real-time crosshair readouts. Built for pilots and mechanics who take engine health seriously.
Five synchronized panels. Live crosshair readout. Real alarm detection from your instrument data. Built for the cockpit mindset — clear, fast, and honest.
Load .jpi files from JPI EDM-700, EDM-830, and EDM-960, and .csv files from Electronics International CGR-30P instruments. Also accepts JPI EzTrends .csv exports. Unit conversion handled automatically — metric files display in °F and PSI. More manufacturers coming soon — contact support@egtcht.com with your data file.
EGT/CHT, CHT Rate (°F/min), EGT/CHT Differential, Alarm state, and Supplemental data (battery, oil pressure, oil temp) — all locked together with a live crosshair that reads every channel simultaneously.
Drag to select any time window. Scroll to zoom amplitude on any panel independently. Pan with keyboard or toolbar. Right-click resets all zoom instantly. Time zoom and Y zoom are independent on every panel.
Alarm limits read directly from your .jpi file. CHT high, EGT spread, cooling rate, battery — the Alarm panel shows green until a limit is exceeded. Alarm state and triggering sensor shown at every cursor position.
Switch between a clean light theme and a high-contrast dark theme. Smoothing control (3, 5, 9 pt moving average) removes electrical noise without hiding real trends. Custom trace colors — right-click any channel label.
EGT peak finder with per-cylinder breakdown and cruise average deltas. CHT analysis flagging the hottest and coolest cylinder by peak temperature. Shock cooling event detection (−75°F/min). CHT spread analysis vs the 65°F normal guideline. Side-by-side flight comparison. PDF flight reports. CSV export. All in Pro.
Your engine monitor is telling you something. Are you listening?
Every flight, your JPI EDM or Electronics International CGR-30P records hundreds of data points — EGT trends, CHT peaks, cooling rates, battery voltage. Most pilots never see that data after they land. EDVA changes that.
Spot the EGT spread that hints at a partially plugged injector. Catch the CHT that crept toward the limit on climb. See which cylinder is running hot — before your mechanic does at the annual.
This demo includes four real flights from a real aircraft. Zoom into any segment, move the crosshair and read every channel live, generate a PDF report, and see the EGT+CHT exhaust valve health analysis. It’s the full Pro experience — with sample data instead of yours.
One-time payments for Basic and Pro. Optional annual Cloud storage. Priced in line with the tools GA pilots already rely on.
Full flight data viewing for JPI EDM and Electronics International CGR-30P instruments. Everything you need to read and understand your engine data.
Everything in Basic plus professional analysis tools and your first year of Cloud storage included.
Save every flight to your personal cloud library and access it from any computer. First year included with Pro purchase.

Not a casual glance at a gauge. A serious tool for pilots and mechanics who want to know what their engine is actually doing.
You invested in an engine monitor — now get the most out of it. EDVA shows exactly what happened on every flight: lean technique, climb temperatures, shock cooling on descent. Build your engine monitoring judgment one flight at a time.
Your engine is your biggest investment. Track trends across every flight, catch cylinder anomalies early, and walk into every annual with data. When something looks wrong, you'll see it before it becomes expensive.
Pull up any flight and zoom into the run-up. Check the mag drop, see which cylinder ran hot, track CHT rate on descent. Compare pre- and post-maintenance data side by side with the Pro comparison tool.
