F150_FX4

Recently picked up an '05 SCrew and was hoping someone with SCT tuner experience could chime in.


I purchased the SCT X4 tuner and had it married to my '16 Mustang. Is it possible to use the SCT X4 to read vehicle info and change settings on the F150 if the handheld tuner is already married to the GT?


I'd give it a try, but I'm concerned I'd royally fubar something. Hoping someone has a bit of experience with the SCT on multiple vehicles and can give their $0.02.


Pic for attention - and thanks in advance

No, it can only be married to one vehicle at a time. You can use it to read codes from other vehicles, but not to tune 2 at a time. You could always ask SCT support this as well.
