    Default Tuning for Economy can be done several ways.

    One way is to increase the Efficency of the engine via timing or removing Slop from the trans.


    The trans Slop is the easiest to fix. Remember though, the more line pressure you run, the more loss you have due to the trans pump being harder to turn.

    Shifting patterns play a big role in the way the vehicle uses fuel. Think of this, When a car goes up a hill, and you see yourself having to press the TPS to 50% or more and the car just boggs down and you keep pressing it in more, Would it have been better for you to just allow a lower TPS vs Downshifting pattern? So as you go up the hill it just either unlocks the converter or performs a downshift to the previous gear. Now the vehicle will climb the hill with ease. You will see that the injector pulse width "Fuel used" will be much less as you climbed the big hill.

    Another route is to use the Custom os3.

    Joecar did an excellent autotrans tutorial.
    If you do a search you should find the thread.
    I think the thread has a pdf attached to it too.

    Another Secret is to monitor and set up the o2 switching tables to be more fine tuned and tighter. BUT!!!! you have to have the ve and maf tables perfect before you do that.

    The reasoning on that is with the switching from rich to lean, rich to lean to get a "Averaged" stoch wastes fuel if it is on the richer side of things and doesnt spend as much time on the lean side.

    I tuned an 05 Tahoe last week, and I really spent some time on the timing table in the cruise areas and he drove about 300 miles on his trip home and back, he called and told me that his MPG average went up about 2-3MPG!

    Yes from what I've read, but honestly I haven't tried to really mess with it.
