Was hoping someone out there may have a factory cal for a 2009 Chev Yukon Denali 6.2 VVT Flex Fuel, or similar from a GMC/Cadi truck.
OS = 12630501 or maybe 12628983).
12630501 and 12628983 are in the E38 cal folder in EFILive, so they have been through for deciphering and are out there!
Thanks all!
