bill98 Posted April 1, 2019 Report Share Posted April 1, 2019 My JPI830 finally decided to start allowing me to download data and now I feel a little more comfortable that my engine is broken in so I tried the whole lean of peak thing yesterday. https://savvyanalysis.com/my-flights/1005633/293a3a42-a53c-4ad7-9cf6-ece2a1d4c0e3 First flight with a date of 31-March shows erratic temperatures - I was dealing with my dad, turbulence, and just playing around with the mixture. 2nd flight with a date of 31-March I tried to set it and forget it. Looking more at the second flight for insights. My #3 cylinder is always the hottest but never goes red. For LOP / ROP flight - one wants to look at the EGT and then see a drop correct? Not looking to be roasted, just some helpful pointers *** disregard any way off RPM readings, I think I have a ground issue. Typical RPM setting - 2600ish and around 23MP as I have been trying to run the engine hard during break in. Quote Link to comment Share on other sites More sharing options...

I’m 75% certain I’ll be down there for a Buddy’s wedding at the end of April. You have a place a guy could tie down a F for a weekend?

Let me know when you firm things up. 2 Quote Link to comment Share on other sites More sharing options...

Should know by end of week. All depending on Wife's travel schedule for work. Quote Link to comment Share on other sites More sharing options...

I do have an oil change that needs to be done and a compression check! Do the Cylinder Temps differences raise any concerns? #3 does not seem excessively high by any means. I am still using Straight 100 Oil. Quote Link to comment Share on other sites More sharing options...

No concern at all. I usually have a 60 to 70 degree difference between my hottest and coolest cylinders. 1 Quote Link to comment Share on other sites More sharing options...

I think you already answered this before, but if you have a spark plug gasket temp probe or a bayonet ring probe on #3, your CHT could be off by 50 or 25 degF respectively. It could be colder or hotter depending on the engine installation and cowling. My #3 CHT used to read 50 degF colder than all the others with a spark plug gasket probe, and when I switched to the bayonet ring probe, it reads only about 10 degF colder now. 2 Quote Link to comment Share on other sites More sharing options...
