Windstar vehicles: DO NOT perform PCM reprogram. Check for potential lean contributors and/or perform Octane Adjust only. Refer to the following Octane Adjust Procedure for details. If the spark knock condition, (2000/2001 Taurus/Sable), or transmission harsh engagement, (2001 Taurus/Sable) is still present after performing normal diagnostics, check for potential lean contributors and reprogram the PCM. On a very small percentage of Taurus/Sable vehicles, it is still possible spark knock may be present after PCM reprogramming. If spark knock can be verified after PCM reprogramming, proceed with the following Octane Adjust Procedure. OCTANE ADJUST PROCEDURE Use the New Generation Star (NGS) Tester to perform an Engine Octane Adjustment using the following procedure: 1. Using NGS Service Card (11.0 level or higher) and Flash Cable, select "Service Bay Functions". 2. Select "PCM (Powertrain Control Module)". 3. Select "Module Configuration". 4. Select EEC V or PTEC Vehicle - by TSB. 5. Press trigger to continue on emission compliance authorization screens. 6. Highlight the Octane Adjust column and press trigger, then rotate the dial to change the ignition timing from "No Retard" to "Retard". Press trigger again. 7. Highlight Fuel Octane and press trigger, then rotate the dial to set the octane to 87 Octane and press trigger again. 8. Press the Start button. You should receive a message saying that the change has been successful.
May help, it's a Octane adjustment for Windstarts, unfortunatly it has to be done by Ford.
