Is there any provision in the software currently to control AFR during warm-up and at what temp the warm-up cycle stops?

I see AFRs from 10.3-11.3 until the engine warms past 174F. This causes my plugs to be covered in a thick black coating of carbon as well as wasting fuel. Am I missing something? I had Specialty Z tune it but nothing improved in that area.

There are warmup enrich tables, but normally they don't need to be altered. See the Nistune mapping guide on our website for details on all the maps, including this
