Base Pulse Inverse Term. Does it have to do with intake runner temps? At first i thought bpw, but there's temp numbers in the table.

the table is used to account for the change in air density(therefore, oxygen content) vs the intake runner temp. intake runner temp is a calculated value, primarily influenced by coolant temp and air temp, along with some modifiers, primarily airflow.
the numbers in the table aren't necessarily real-world values, they're essentially a placeholder to help complete the airflow calculation, kind of like the BPC vs %EGR table. generally, you're not going to need to mess with it, there is another table to play with should you have relocated your IAT/MAT sensor or otherwise have a condition where the actual intake runner temp is different than what the calibration is expecting, look towards the F150(and possibly F151) table. that is how to shift the IRT calculation more towards the IAT signal's or the CTS signal's value.

Ok. Thanks.
