SCT Device Update!

This probably has already been covered but a reminder to check your XCal 3s and Xsf3s to be sure the firmware is up to date.

Details here on the SCT site SCT Performance - More Power! Less Fuel!

Mine wasn't done and it pretty much locked me out. I wrote an 87 Octane tune into the truck and all was good until I tried change to a different tune and the tuner said "wrong vehicle". After several calls the helpful folks at SCT got me sorted out. Took me about an hour.

It wouldn't even let me go back to stock and the truck will need to go to the dealer here soon.

Hope this helps

When you update the device you have to make sure the "Stock" Tune file is installed in the vehicle first or it will lock the device and give the "wrong vehicle" message. This is very important.
