Ok, finally going with an SCT. Just wanted to clear up some terminology before I go talk to Vit, and apologies to those members I’ve PMed about this if I repeat my questions. The X2 is the actual chip that plugs in to the OBD port and has the selector switch to switch between the tunes I order. The SCT itself is the handheld unit that allows me to create new tunes and (with the aid of a computer) adjust existing tunes. The SCT itself can tag along and data log, then I can later download its info to a computer and see how I did.
SCT does sell a 4 bank chip that you can switch tunes by turning a switch.
The Xcal2 plugs into your OBD port and allows you to “flash” the PCM. The Xcal2 unit holds 3 tunes plus a stock tune, and you can switch between each by re flashing the PCM.
The Xcal2 has the ability to datalog using a program from SCT called livelink.
If you want the ability to tune your vehicle yourself I’d strongly suggest the “Pro Racer Package” which gives you the advantage program which allows you to make any change you want.
I hope that this helps you out. If you need more information go to the SCT website and go through all the “Ford Products” section and read up on the different abilities.
P.S. If you do want the chip, you’ll have to get something called a “Raptor” datalogger from SCT also.
