There are 2 Manifold Air Temp parameters found in the parameter list for the GM LT4 motor, and both read differently. Can someone explain the difference?

There has been two MAT's for the LT engines since 2013.
I logged both and compared the output to the IAT retard output based on the IAT table and decided which to delete and which to keep.
Was it the bottom one that you kept? That is the one I thought matched up with the intake temperature correction.Quote:

Best to look at the MAT that increases with boost.
