The supplied OBDII transmission tuning handheld is used to adjust shift points, tire size and gear ratios. The Terminator X V3 software provides the ability to dial in Torque Management to optimize the desired shifting characteristics when using a 6L80/90E Transmission. Terminator X V3 software also allows a user to control the Secondary Shift Mode within the Transmission TCM and allows use of Tap Up/Down Shifting. The Terminator X V3 PC Software, you can have virtual torque management tables, virtual TPS tables for dialing in shift characteristics, and drive by wire (DBW) and timing torque reduction tables for smoother shifts.
