A calibration contains all the information (settings and table values) which can be changed in the ECU. The normal calibration file extension is .fpcal.
For a new vehicle it is possible to either load an existing calibration as a starting point (if a calibration exists) or create a new calibration. Here we'll cover creating a new calibration.
1. Open the New Calibration window from the File menu.
2. Make sure the correct vehicle type selected.
3. Determine if an AFM or MAP calibration will work best for you. Generally the AFM calibrations are suitable for a stock vehicle with simple bolts ons, and the MAP calibrations are suitable for everything else. If you're using larger injectors, forced induction or large cams then use a MAP based calibration.
Note that MAP based calibrations will disable the oil life indicator (it will stay at 100%), and when switching from a MAP to AFM calibration the Maintenance Minder will need to be reset.
4. Optionally, click on Show Filters to reduce the number of calibrations which are shown.
5. Double click on the calibration name to close the New Calibration window and create the calibration.
There are tens of thousands of combinations of bolt on parts, so there may not be an exact match for your engine modifications then select the closest match. The modifications which make the most difference for tuning are intake type and the presence of race headers, so select based on the closest match.
