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
