    The service department was horrible! My other issue is that I'm getting the timing chain slap and the dealership verified that it was making a noise. My experience was pretty bad with the service department, I had an appointment for 10 am on Thursday, dropped it off the day before. They didn't call me all day Thursday then Friday I had to call them 3 times before they got back to me on friday. When I asked if the the tbs for the chain slap would be covered by the extended warranty the service guy told me he sent the paperwork to verify that they would cover and he would get back to me on Monday. That's was a week and a half ago! And I still haven't heard back from them. Anyway you could help me would really be appreciated.
    Thank you
    Zach

    I think I know the answer, but time will tell. I have been battling "battery saver mode" for a month now.

    As many of you know, the PCM controls the alternator. In fords newer trucks, the alternator actually shuts down to get better MPGs. If you drive short trips like I do, the alternator is NEVER doing it's job. These trucks need a lot of juice....and I am not sure why ford would do this.

    The good news is, your turner can CHANGE the alternator "shut off programming" during PCM tuning/re-writing. Essentially making sure that the alternator is consistently charging the battery no matter what throttle position.

    A few months ago I returned my PCM to stock format (no tune). and sure enough, as soon as the cold winter hits ...BOOM, battery saver mode appears and radio shuts off. I have loaded my performance tune and hopefully now the alternator is constantly charging the battery. Another person I have spoken with has fixed their problem with a tune as mentioned above. SO ....if you have the chance to get a custom tune DO IT. And tell the tuner you want the alternator running 100% with no shut off. I truly believe these trucks need constant juice from the alternator to keep up with everything !!! The battery threshold should NOT be lowered to under 50%. This is just a workaround that will lead to a dead battery over time.

    A way to bypass the battery saver mode without having to "tune" your truck, as long as your battery and generator are in good operating condition, is to unplug the inductive pickup at the negative battery cable right by the battery. This will allow the alternator to work like a normal alternator.
    I think Ford's idea to implement this on-demand charging crap was to gain minute mpg gains during EPA testing cycle, however in the real world, we're better off with a proper voltage regulated charging system.

    I uploaded my revised tune from torrie that included the battery management thing-a-ma-jig and I don't seem to have the battery saver come on instantly anymore as well as the long key-turn starts.

    battery saver mode cannot be bypassed by pulling the sensor. The data is stored in the computer.

    I kind of hate the battery saver junk. Let us play roulette if we so choose by blaring our music in the front yard while raking leaves! I can only have the radio playing with the truck off 20 or 30 minutes (just a guess) before I have to turn the truck on for a minute. I think it's too conservative. I like to go to a drive in movie where the sound plays through the vehicle speakers. It's kind of rude to fire up every 30 minutes.

    I'm not talking about the time out effect. I'm talking about when the system goes haywire and within a few seconds of the truck being shut off it goes into battery saver mode. With the inductive pickup unplugged I get a steady 14.2v and never have the warning.

    My sister took her young boys to a drive-in, pulled into the spot, grabbed the speaker off the pole, and when she couldn't get sound out of it, moved (three times in all,) hoping she'd find a speaker that worked.

    She finally gave up and asked the guy selling popcorn what the problem was.
