    What mask are you using? Is it $0D, $0E, $E6 or $31? I hand edited my bin and entered the code using the hex editor. It works great in $0D. After you enter the code, you have to wire in a fan relay. The PCM turns on the ground side of the coil for the fan relay to make the fan run with the temps you set in the code. Which fan code are you wanting to use?

    The $OD fan control XDF attached has all of the parameters you will need to make the fans do whatever you want . Simply select it as your XDF file.

    When you save the attachment it will name it as a .php file , after downloading or in the process of downloading simply change the file extension to .xdf and all will be fine .

    Its a windows problem , Billy Gates out to get us all again ........

    I have no problem saving the link from Linux using Firefox or XP using IE. There is nothing wrong with the xdf file posted above by Nasty-Z.
