ACTION
This updated service calibration addresses a number of vehicle driveability conditions. When servicing 2003-2004 Super Duty and Excursion vehicles equipped with 6.0L Power Stroke engine built before 9/29/03 (can be verified by the Injection Control Pressure (ICP) sensor located at the rear of the engine) reprogram the PCM/TCM/FICM modules to the latest calibration level (B27.9) or later. This calibration should only be installed on customer vehicles that exhibit one of the conditions addressed above.

NOTE
THIS LATEST CALIBRATION INCLUDES ALL CHANGES RELEASED IN PREVIOUS CALIBRATION UPDATES.

NOTE
INSTALLING THIS CALIBRATION REMOVES PILOT INJECTION CONTROL.

NOTE
PRIOR TO INSTALLING THE UPDATED CALIBRATION, ADVISE THE CUSTOMER THAT THIS UPGRADE WILL SIGNIFICANTLY IMPROVE ENGINE IDLE AND LOW SPEED PERFORMANCE. IT WILL ALSO SLIGHTLY INCREASE THE ENGINE SOUND LEVEL DURING WARM IDLE, WHICH IS A NORMAL OPERATING CHARACTERISTIC OF DIESEL ENGINES.

SERVICE PROCEDURE

Before reprogramming, verify correct engine oil level and confirm proper operation of the ICP/IPR (refer to PC/ED Manual). Calibration updates are available on WDS software version B27.9 or later.





Obtain an Authorized Modifications Decal (FPS 8262 - obtainable through DOES II, 25/pkg) and list the date, dealer number, and summary of modifications performed. Select a prominent place adjacent to the Vehicle Emission Control Information Decal suitable for installing the Authorized Modifications Decal. Clean the area, install the decal, and cover it with a clear plastic decal shield.
