DEF Parameter changes

[Zkeene21]

Is there anyone on here that has capability of changing DEF Derate parameters for the ongoing issues with DEF Headers/QLS Units? I know the OEM companies are starting to roll them out due to shortages of parts but I have been waiting for over 2 months on some units and still have customers with truck setting idle unable to use. Some being 2020/2021 models. I assume the OEM are just changing the range at which the ECU essence a problem with these units in essence widening the acceptable operating range.
