I got my sct haldheld in the mail the other day, connected it to the car and i'm getting a couple of errors, the tuner won't connect to the ecm.
The guy i bought the car from mentioned it was tuned, and from what little i've read (very little) i'm gonna have to take the car to ford to reflash the computer to stock before i can upload anything off the device?
Is that correct? Or is there a way around it? I'm unsure of how it was tuned, if it was on a dyno or canned tune or even if it matters.
I actually ordered it to change the fan settings because i changed the thermostat, not realizing i wouldnt be able to even do that.
