Correction table’s value is used to increase the positive dMAP Correction value. Therefore, if the
current dMAP correction value is 200% and the Run Time Correction value is 25%, the ECU will
increase the dMAP 200% correction value by 25%, relative to the time at which the acceleration event
occurred.
The amount of Run Time Correction fuel is decreased as time transpires and the engine warms up.
The first cell in the table, all the way to the left, represents the first ½ minute of engine run time. The
cell all the way to the right represents the end or eighth minute of engine run time. The Run Time
Correction table’s input values need to decrease as you work from the left to right.
While the engine is running, a “real-time Ellipse” will move within the Run Time Correction table
relative to the current Run Time Modifier “operating point”. Use it as a point of reference to help
calibrate the Run Time Correction table.
To change a value in the Run Time Correction table, move the cursor using the PC’s mouse or arrow
keys to the cell to be changed. Input the desired value and hit
“Enter”
to save the change
The inputs shown in the table below can be used as a baseline.
