This is the only table with AFR ratios I could find. It's an Open Loop table, but I think it is referenced for Closed Loop as well. See pic for more info.

for closed loop you need to alter the closed loop fueling offset tables they are the offset off 14.7 so if the table has -0.7 in it it means you will target 14, theier are two tables a and b alter both
