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.
Same screen as above with the window maximized. The values shown in the table below can be used
as baseline.
The values in the X & Y axes are factory set and therefore not configurable.
