so I have a grand Cherokee srt8 that I tuned a while back. but the customer only wanted the engine tuned back then. now hes back for the tranny tune but when I read both the tcm and ecm its asking for me to relicense the ecm when all I need to license was the tcm. is there anyway around that as I don't understand why its asking for the 2 credits when the engine only read is already licensed and works.
