engine analyzers

[gregorydshanks]

Any recommendations for an engine analyzer for a MXT-180 with a just rebuilt 0-360? I get all kinds of opinions on whether CHT or EGT is more important, but most importantly, I would like to know the precise fuel flow.

I have been extremely happy with my JPI system for the 14yrs I have had it.

Only quibble is some of the bars have gone missing with the older illumination technology. Not hindering function. My guess is they have gone to newer led type bars.

EGT/CHT ate to live by. Added fuel flow later and is godsend with Maule fuel gauges

+1 on the JPI.

OEM option on my plane.

I would not recommend not flying with and knowing how to use and interpert an engine analyzer.

My A&P installed the G3 in the M4 with an IO360.
Pricey but well worth it...

My local shop strongly recommend the JPI, but I much prefer the display of the Insight G3 or G4. You know at a glance if you are safely under Rich of peak, safely over Lean of peak, or in the danger zone, and by how much, for each cylinder. That's the one I'll be upgrading to, contrary to my local mechanic's recommendation.

CHT for all cylinders seems to be the crucial piece of information, from what I've read. EGT, specifically EGT peak, serves as the reference for knowing how much you're Rich or Lean . . . and the limits discussed there are all in the service of . . . maintaining a healthy CHT (Below 380, and never above 400F)

The EAA website has a series of webinars by Mike Busch that are extremely informative.

This is the first class covering the basics of safe leaning:

I found these informative, reassuring and persuasive.
