F. Verify correct current calibration and new calibration information. Then click Next.

NOTE

The total number of calibration IDs in the calibration file corresponds to the number of
reprogrammable processors in the ECU.

Each calibration file may contain up to three separate calibrations.

Figure 17 shows an example of the update procedure for a two-processor ECU.
