I know I know.. finally I’m learning about computer controlled vehicles, modules, tuning etc. Maybe I can be pointed in the right direction here. 08 6.4 about 70k mileage.., I got a SCT x3 Ford 3000, unmarried, no tunes from my knowledge, I was trying to update firmware… probably needed not sure.. wanting to del the usual crap. Does anyone still or is able to create tunes for this device? Do I need to update the firmware? I just want the longevity outta this truck. Was also curious could the X3 or is it same as j2534 pass thru? I like to know how things work as opposed to simply plug n play, press a few buttons.
