Cars commanded AFR going very rich at WOT when PE table commands a higher AFR?

[Bill@HPTuners]

If your PE table is commanding, for instance, 13.0:1 afr but in the scanner you see your commanded AFR dipping to 11.7:1 or somewhere thereof check your Cat over temp tables, if you still have COT enabled it will take over the commanded fueling if the requirements are met.

In most LS1 calibrations the max enrichment rate is set to 1.25 from the factory

Stoich/eq ratio=commanded afr

14.7/1.25=11.7 commanded afr so this is the most common answer.

because thats your widebands reading & has nothing to do with what this thread is regarding.

This thread is talking about COMMANDED AFR not ACTUAL AFR.
