The inputs shown in the table below can be used as a baseline.
47. MAP Vs. Coolant
The GEN3 ECU’s MAP vs. Coolant table offers an improved warm up routine. The table
applies a fuel correction (a % increase or decrease to the base pulse width) as a function of both
Load (MAP) and coolant temperature. The cells in the table represent ninety six (96) different
MAP and coolant temperature combinations.
The same calibration technique should be used with this table as was employed with the base
fuel map. This table should be calibrated after the base fuel map.
To change a value in the MAP vs. Coolant 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.
