EBL P4 Flash Update Instructions
READ THIS FIRST!
Introduction
The EBL_P4Update utility is a Windows program. When connected to the EBL P4 Flash ECM via the data logging/flashing port it will update the base code in the ECM along with the calibrations. The process takes a little over three minutes to complete. Once completed your EBL P4 Flash ECM will have the latest firmware in it. The 8 banks of calibrations will also be updated.

1. The EBL P4 Flash update process reads the current calibrations out of the ECM. These are placed into a series of files named Bank_0_old.bin through Bank_7_old.bin.
2. They will be created in the same folder (directory) that the update utility is run from.
3. The update utility will then create eight new calibrations. These are based on the ones read from the EBL P4 Flash ECM.
4. They too are created in the same folder that the update is run from. And are named Bank_0_new.bin through Bank_7_new.bin.
5. The update process will flash in these new calibrations along with he updated ECM code.
6. Use these new calibrations for all further tuning. So copy & rename them as required.
7. Do not delete the old (original) calibrations that have been created.
8. If the update process fails, just restart it. It will need the calibrations that were read out. This is why they need to be left in place.

To update

1. Copy the EBL_P4Update utility into it's own folder (make a new folder).
2. Boot laptop, start the EBL_P4Update program.
3. Select the proper COM port, it will be the same one that the WUD uses (close the WUD).
4. Connect laptop to EBL P4 Flash ECM via USB port.
5. Key-on, engine-off. Wait for COM port to show "Open."
6. Click the "Proceed With Update" button.
7. Wait for the update program to go through all eight calibration banks (about 3 minutes).
8. Once completed double click on the Setup_P4_1-2.msi file. This will install the latest XDF, DOC's, BINs, WUD and so on.

Notes

- An electric cooling fan will run during the update process, be careful of this occurring (keep hood closed)
- Once updated DO NOT USE ANY OF YOUR OLD CALIBRATIONS. Use ONLY the newly created calibrations
- A rapidly flashing SES/CEL light means that an old calibration has been used with the new code, or vice-versa
- The update includes all new base calibrations that are already updated
- The update utility can also update any original stand alone calibrations. File->BIN Updates... (ATL-F, B)
