A/F ratio vs EGT
From what I understand, exhaust gas tempratures are directly related to the A/F ratio. Does anyone have a chart that correlates the the two? I'm looking for a chart that will say, for example, 250 degrees F on the EGT is equal to X on the A/F. Thats what I'm looking for.
Thanks,
Thanks,

Advancing ( or retarding ) timing while keeping the same A/F ratio can dramtically effect EGT's

problem with EGT is it's not as fast as a wideband from what i understand.. basicaly my car has both now.. the GReddy EGT and a techedge wideband setup... once i start tuning i'll post results of how similiar it is.

Haven't we ALL heard this
They are not related that much. So many factors effect your EGT. Things like Ambient temps, intake temps, gas quality, air flow around your engine bay, and many other things. AFR is read as a Ratio. Egt is just anouther lil gauge to chunk money at. IMOP.
There is one place you would catch me using an EGT. Piston powered airplanes.

Actually, the Metro which uses a Garret engine does use an EGT gauge. Not for the reasons we do. So you do not melt your engine.
But yeah.......no O2 sensor
