Flex fuel ?'s on '21 ZL1

I have done this with success on my previous '17 ZL1 and '18 Silverado but have problems logging the commanded air/fuel on my '21 ZL1. The sensor is definitely enabled and reading the ethanol percentage but I cannot see a change in the commanded air/fuel. Yes, I have the stoich table set to the corrrect values for alcohol. Am I not logging the correct value as there doesn't appear to be more than one commanded air/fuel parameter? Any ideas or comments would be helpful...TIA!
