Message: [QUOTE="CurtisF, post: 1162360, member: 829"] Charles, here's some tuning stuff that has worked with me. VDHx likes to give me fits when it comes to the torque converter lockup. What I've changed helps me to make it lock in 2nd and keep it locked, where just changing only the lockup tables and shift strategies by themselves would not work. The combination of everything below forces it to lock the TC and it works on my truck perfectly. I'm using Minotaur, can't remember if you are or not, so not sure if some of these settings are labeled the same. Parameters: - Minimum time since 1-2 before 2-3: 2.00 (default is 0.00) - Maximum accel rate for anticipated shifts: 17.00 (default is 6.00) - Minimum accel rate for anticipated shifts: -10.00 (default is -6.00) - Switch to use RPM anticipated shifts: 1 (default is 0) - Delay converter lock after 3-2: 0.13 (default is 2.5) - Delay converter lock after 1-2: 0.00 (default is 2.50) - Delay converter lock after 2-3: 0.00 (default is 2.50) - Delay converter lock after 3-4: 0.00 (default is 2.50) Maps: - Trans TV Pressure Shifts (1-2, 2-3, 3-4): raise to desired firmness, varies based on trans build. - Converter lockup duty cycle: Raise your duty cycle, my minimum is 40% at 5 ms (default is 14 at 5 ms), varies based on trans build. - Target slip time (1-2, 2-3, 3-4): Cut by about half over stock, depending on your trans. - Torque reduction (all gears): zeroed out to 100% across the board. Functions: - Shift schedules (all gears): Mine are close to stock, not much of a change. - Converter Lockup: See screen shots below, red is original stock calibration, black is modified (do the same for Converter lockup hot)....
