Once you insure that your tire size and gear ratio are still correct and have all the other settings to your liking, Go to the "Part Throttle Upshift/Downshift" and "Torque Converter Lock/Unlock" choices. These change the speed at which these events happen by a small amount. As I recall, the Up/Downshift points can be adjusted +/-2, +/-3, and +/-5 mph for each gear change. I wanted mine to change at a lower speed, so I adjusted all of them to the negative maximum. Supposedly, this can improve your fuel economy a bit by getting you into higher gears sooner and keeping you there longer. I just wanted to reduce the tendency of the transmission to downshift when I thought there was still a power reserve. I did the same thing with the Torque Converter Lock/Unlock points. These are a bit more aggressive and there are four of them (one for each gear). They can be adjusted +/-2, +/-3, +/-5 and +/-10. Again, I reset all of them to the negative maximum, hoping to keep the TC locked up longer. It seems to have helped. I don't get the overeager unlocking on the slightest incline that I used to have. Note these "Part Throttle" adjustments have no effect whatsoever on WOT shifts. And, since part throttle shift and TC change patterns depend on both speed and throttle position, just a little more throttle at a given speed is all it takes to cause a downshift or TC unlock if that is wanted. Hope this makes sense. - Jack |

The intent is to keep the engine RPM as low as possible, while not sacrificing driveability. The power is still there, if I demand it with a heavier foot. - Jack |

one other thing i notcied from going to the canned tune to the custom tune is the shifts seems less harsh. with the canned tune when it shifted you could really feel it almost like there was a shift kit on the truck. now with the custom tunes its a lot smoother. is this normal for the custom tune. off subject my exhuast seems not as loud

The change in exhaust sound is probably the result of the way Bill has mapped the fueling and timing. - Jack |
