LB fair enough - so what does the redline indicate ?
I have no argument with multipoint EGT and CHT - have this on my RV. But many older aircraft just had basic CHT and EGT if any at all.
EGT is not the problem - Excessive CHT does the damage. I just lean to give smooth running with hottest cylinder CHT no more than my self imposed maximum of 380 degrees F - considerably less than manufacturers max. EGT is not relevant.
I like to keep it simple. IO-360 with one electronic and one normal mag using above gives me 26 l/hr at economy cruise 2200 rpm 140 kt tas.
