Positive dMAP correction value after accelerating the engine at a given coolant temperature.
The ECU decrements the dMAP correction by the MAP AE Decay Rate. A MAP AE Decay
Rate of 3 represents 3 crank interrupts per 1 step decrease of the dMAP Correction until it
reaches zero. In other words, if you input the number 3 into the table, after 3 crank interrupts the
