Altering the transmission data doesn't provide more power, but can provide better 0-60 times and quarter-mile performance. Most trucks benefit from a slight increase in WOT shift points. The more the truck is modified, the higher the typical shift rpm point because the engine makes its peak horsepower at a higher rpm. If you have performed a gear or tire size change and change the gear and/or tire specs in the speedometer setting, it will automatically scale the transmission tables for you. The WOT shift points are changed in the WOT Shift RPM vs. Shift Normal table and is done in rpm values for each gear. To make the downshift of the truck more aggressive, go into the WOT Shift Speed vs. Shift Normal table, which is specified in mph, and move the downshift mph values up a few mph. Since the table will command an earlier downshift, this will eliminate the lag on the downshifts. Car Diagnostic Tool
The part-throttle shift points are done by mph as well, and realized through the Shift Speed vs. TPS vs. Shift tables, and even though there is an area there for WOT throttle ranges, they are not used since the WOT tables become the default. These tables are typically only changed for part-throttle feel on heavier modified vehicles with a stouter camshaft. After setting the shift points, you can work on shift firmness. This is done through the A4 Shift Properties tables. First, you can modify the shift time ("Desired Shift Time vs. Torque Normal") to decrease it to get the transmission to complete its shifts quicker. You can also go through the other shift pressure tables and add or remove line pressure to achieve the shift feel you desire. This is one area where your subjectivity comes into play; everyone seems to have a different idea for how they want their transmission to shift. Launch X431 Diagun
If you already have a shift kit in the transmission, you do not want to add much in the Pressure Modifiers because you can damage parts and/or seals if you aggressively combine the two. For an off-road vehicle equipped with a manual transmission, you can delete the CAGS "Skip Shift" (forced First to Fourth shift) in the transmission tables by increasing its enable temperature to one that the engine will never reach.Torque management (a set of tables) pulls out timing during shifts to prevent full power going through the transmission during the period between gears. This is done to make the upshift seem smoother and supposedly to add longevity to the transmission. Carprog Full V5.31
The side effect of torque management is that during the shifts, you can feel the vehicle nose over-under power. Zeroing out these tables (Torque Reduction vs. Torque vs. Shift) or greatly reducing the values will provide a much better feel during shifting when combined with the quicker commanded shifts through the line-pressure tables. Most transmissions do not experience excessive wear from a dramatic torque-management reduction, however, a few people have experienced damage to the transmission. Altering the torque management presents a risk for a stock transmission. If you tow heavy loads with your vehicle, it's best to leave some torque management in the programming.CRP 123 Launch
