    Default Flex Fuel cax for 12587603 and 12587604

    Here is a couple cax files for the 12587603 and 12587604 OS.These have B9021 and the rest the tables were added under the Flex Fuel Tree under B3101-B3110. I named B7000 the Spark blend multiplier to enable B5947. Attached is a 2004 GTO file with the Flex Fuel values inputted that were used from a L59 calibration that have worked for me in the past.
