IMPORTANT NOTICE FOR X3 & SF3's Sold Prior to July 25th, 2008:

SCT has recently updated the firmware for all X3 & SF3 devices. These devices now have different firmware that will effect all future updates for your device.

X3 devices part #3000 sold after July 25th, 2008 will now only be used for custom tuning and will no longer contain pre-loaded tunes. The SF3 device part #3015 will hold 3 custom tunes and will ship with pre-loaded tunes as in the past.

If you have purchased an X3 device part #3000 or SF3 device part #3015 prior to July 25th, 2008, your device is now considered an SF3 device part #3015, even though the device stickers may state it is a part #3000. When updating your device with any future firmware or tune revisions, you must use the SF3 part #3015 device updates or you will receive an error when updating the device.

Devices sold after July 25th, 2008 should use the matching firmware for the part number on the device sticker.

OLD SF3 Firmware, meaning for SF3's that the Serial Number does NOT start with "XP".

IMPORTANT READ THIS: This firmware is used for all SF3 tuners, as well as all X3 Tuners sold before July 25th, 2008.
