Converting EGT to A/F?

[The Traveler]

Does anyone have, or know, what the conversion would be to go from EGT readings to A/F? I will probably be buying an EGT gauge because the wide-band A/F is a little too pricey and would like to know what the equivalent readings are. Does anyone have something like that?

best thing to do is stand next to the gauge as the tuner does his run on the rollers.

also placement of the sending unit will be important on what temps u see. only true EGT gauges read all exhaust ports / 1" from the port.

I figured the location of the sensor was a big variable but was hoping there was some kind of general conversion rule for a set place of the sensor. May have to just watch the A/F at the dyno and compare it back.
Thanks

I purchased an autometer a/f gauge calibrated by gadgetseller.com, and used a pigtail connector from south florida pulley and it works great, dont know if this is what you are looking for but just wanted to offer my opinion.
