I'm not entirely sure either. I believe it's concerning fuel, timing etc. - My Ford dealership called and mentioned there was an update I needed to have installed... wasn't sure if it was the Sync stuff or even if it's just a money-grab. Thanks!
Maybe a dumb question but... when you update the Sync software (from the Ford site), does this also update the computer that the service tech always says needs updating? Or is it ONLY Sync ?
