Some other things for EGT from a pure theory standpoint.

Compression goes up, EGT goes down
If starting rich, leaning the A/F ratio will increase EGT, it will peak at stochiometric, then decrease as it gets leaner still
Advancing spark timing increases EGT till ????? (sorry, having a brain fart and can't remember)
EGR (including internal EGR) will decrease EGT
Detonation causes EGT to decrease? (I think this is correct)
Volumetric efficiency causes EGT to ???? (can't remember this also)


EGT trends with peak cylinder temperatures and thus NOx emmisions.
