Probably my 1st post. Started flying 1980 M20J and know the topic has been well discussed here. I am looking at this broadly, just to get on the right side as I gain experience in these beautiful birds. 2 flights as co-pilot to get a feel and get familiar with cockpit. At cruise 2400/24 MP @ 8.4/8.6 GPH, which I think is pretty good for 200 HP IO360-A2B6D according to the JPI. I was looking at the POH and Lycoming. At 75% or less POH states 14C/57F ROP, std temp. Lycoming states to use peak EGT for same power settings. Being a former machinist, those are not close enough for me.
I'd like to be more precise, but getting stared, can I just use the JPI and keep CHT @350-375 with GPH numbers for leaning and use economy cruise at 75%? I am not a speed demon yet. I have 3-4 landings and the sight picture is much better for me coming from a high wing. And Don Kaye's video was a big help as was my CFI coaching me on speed coming in.
I have seen a wealth of valuable information here.
