51. MAP AE Decay Rate
The third table is MAP AE Decay rate. It is used to determine how quickly to decrease the
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
