Hopefully someone can point me in the right direction here. I'm well versed tuning gm ls engines, but this is the first ford I have tried tuning. It happens to belong to my wife, so any help here would be greatly appreciated.

Anyway, I used to being able to reset fuel trims in the scanner during tuning for ls motors. The only way I can seem to reset the trims on this thunderbird is to write calibrate each time I want to reset the fuel trims. Is this the only way to do it on a ford?
