First you have to write to the ECU to change things such as auto start stop.
Your dealer will always be able to tell if they really want to. Most of it is done on key cycles. They will see how many times your key has been cycled since the ECU was flashed. I suppose you could sit there and press the button or cycle the key hundreds of times after you flash. If something happens to your motor or drive train Ford will.most likely bring in the big guns and they will be able to tell what was done to the ECU if they want. Now we all know that they have to prove that the tune caused the fault. Most times it plays out that they deny the claim with no further evidence. Sure you can take them to court but who do you think has deeper pockets??
Bottom line is if you can afford the motor or something else to grenade dont do it. Even if it's a coincidence it's going to be an uphill battle.
Now sometimes you can get a friendly dealer that will help you as much as they can which is nice. But if something goes bad it will most likely be out of their hands.
I appreciate the run down. That’s what worries me with tuning this motor. I trust the tune more than the motor. If something happens out of sheer coincidence, not even tune related, I’d pretty much be screwed.
So, that’s a hard no I couldn’t use all the other features of the AP unless I wrote a new tune to the truck?
