Savvy Engine Data Analysis

[Tommy]

Hi guys my annual is coming up soon and I am just wondering has anyone used Savvy Aviation (Mike Busch)'s engine monitor data analysis service? If so how much is it and what procedures / power settings did he ask you to do for the analysis?

Back when he first offered the service, and my engine monitor (JPI EDM-700) was new to me, I subscribed for a year, giving me (I think) five analyses covered under the subscription payment. I used three of them, I think. One just submits downloaded files from the engine monitor, noting what was going on at key points in the flight that's been recorded, hopefully to include a few passes of the so-called GAMI lean test and at least one good in-flight mag check., all done according to procedures you can find by reading or listening to Mike's EAA webinars and/or reading John Deakins' AvWeb articles.

 

The analysis is good, and the folks that provide it are responsive to follow-up questions. At some point, you should probably begin to get a feel for what you're looking at on those data dumps, and probably only need the professional analysis to confirm what you already suspect. And then, of course, as you tune in your engine so that it runs perfectly, there should be nothing to see that's anomalous until something goes wrong, and by then you'll be so good at interpreting the data yourself, you won't need Savvy anymore. 

 

I think it was $125 for a year (back then), but you should check their web site. As part of the learning process, it's absolutely worth it. As Derek Bok said, "If you think education is expensive, try ignorance."

 

Good luck!

I only subscribe to Savvy's FEVA monitoring service.

I do run the Flight Test Profiles as described here:

I think the FEVA is extra piece of mind.
