Heated Seats Temperature Change

Many asking for changes, so......
Module FCIM
High 7A7-01-03 xxxx-CCxx-xxxx
Medium 7A7-01-03 xxxx-xxCC-xxxx
Low 7A7-01-03 xxxx-xxxx-CCxx
C is what you are changing and nothing else.
Defaults are
High 5A = 45 degrees C
Medium 46 = 35 degrees C
Low 32 = 25 degrees C
Late model vehicles MY21.25+ may now be default of
High 78 = 60 degrees C
Medium 46 = 35 degrees C
Low 1E = 15 degrees C
Maths are HEX to DEC / 2
So if we want high to be 50 degrees and this works well on the newer seats the it will be DEC 50 multiplied by 2 to HEX = 64.
So high would now be 7A7-01-03 xxxx-64xx-xxxx 50 degrees C
I would do a quick calculator but do not have time today.
Sample for those that want it hotter by 5 degrees across the board.
High 7A7-01-03 xxxx-64xx-xxxx
Medium 7A7-01-03 xxxx-xx50-xxxx
Low 7A7-01-03 xxxx-xxxx-3Cxx
