The AFR pid is the EQ ratio, not an actual number but it's easy to figure out the number with math.

Take the stoich rate in the computer which for stock is 14.68 and divide it by the EQ ratio to get a commanded target AFR. Likely it will read in the mid 1.2XX to 1.3XX as the RPM rise. Stock calibrations will call for low 11's to high 10's for air fuel ratio. It should be pretty close to that if you have a wideband in the exhaust.
