I installed bungs for an O2 sensor in each head pipe on my engine. I then recently bought an A.E.M. afr gauge and installed it temporarily in the car. It seems to work fine, BUT, although the instructions for installing it were great, there is nothing included for tuning with it. This is a street driven car.
Does anyone have a good understanding of what to look for when trying to tune with one of these things? Like, Idle, cruise, WOT? I'm pretty sure that I can do the necessary carb changes necessary, just looking for assistance with what I should be looking for.
Any hints would really be appreciated

Regards
Jim

Lite throttle no load could be as high as 15:1 or 16.

You can get that as lean as you like and still be drivable.

For wide open full load somewhere around 13.0 would be where I start.

Idle in the 13s or 14s
