7.1.11.6 ITB Load Calculation in Alpha-N Mode When the throttle position is greater than or equal to the
ITB load TPS switchpoint curve and the MAP value is greater than or equal to the %Baro switchpoint, the tuning
algorithm will take the array of cells from the VE table above the ITB load at TPS switchpoint curve and interpret
this array within the context of TPS position. The lower TPS value used for this interpretation is taken from the ITB
load TPS switchpoint curve and the upper TPS value is always 100%.
For example, if you have allocated the region between 60% ITB Load and 100% ITB Load on your VE table
for use in Alpha-N tuning and also assigned a value of 10% TPS on your ITB load TPS switchpoint curve then a
TPS value of 55% would yield an ITB Load value of 80% and the VE bin for 80% ITB Load would be used. In this
same example, a TPS value of 10% would use the 60% ITB Load bin on the VE table and 100% TPS would use
the 100% ITB Load bin.
