so i went to flash my truck about 2 weeks ago to the canned "street" tune on my sf3 that i got about 3 months ago... ive had it on my truck before and it worked just fine. but when i went to flash it this time it got to the loading tune stage and froze... 3 times. tried another tune and the same thing happened. then it told me the device is vin-locked... idk whats goin on here. ive tried and tried to get in touch with sct and have yet to be successful. somebody please tell me what ive done wrong...:dunno:
Go on the sct tech support on their site and you can download recent fireware up date. Then go onto your SCT updater on your computer, put your sct tuner into firmware mode by holding down the cancel button then load the firmware update onto your tuner. It probably wouldn't hurt to update your tunes from the site too while your at it. The only thing I dont know is whether or not the firmware update is going to reset the stock file on the tuner. But if that is the case you can save your stock file onto your computer before you update it, which would be a good thing to do if your tuner gets messed up :doh:
when that opens click "device updates and download"
1) select the x3 Ford
2) device firmware
read descriptions to decipher which of the downloads suits you, it should be the first one:
X3 Ford Enhanced Flash Device Firmware
Application: X3 Ford Device PN:3000
Current Version:1.2.116-3000
save that to the "tunes" folder that you just made on the desktop, once this is done, be sure the X3 is disconnected press and hold cancel, and plug the X3 in release the cancel button approx. 3-5 seconds after connection is made and open up the X3LW updater again. Once open click "update firmware" and select the new firmware that you saved there, once completed (it will take several minutes) you should disconnect and reconnect the X3 and load the tunes with no problems.
