Please find below the current features list for the EcoDiesel transmission tuning (both Jeep and Ram EcoDiesels):

• Eliminates 2-1 downshift hesitation at low speed tip-in maneuvers (i.e. rolling stop sign re-acceleration)
• Upshifts earlier in all conditions for improved fuel economy.
• Downshift criteria revamped to best utilize engine torque curve and stay in each gear longer.
• Hill mode optimization to prevent gear hunting
• Refinement on shift scheduling in altitude to provide better engine responsiveness
• Revamped warm-up mode scheduling to provide faster engine warmup (i.e. 1-2 gears lower compared to normal shift maps)
• Increased minimum engine speed after upshift during DPF regeneration for better regen efficiency (this feature will only appear with the GDE Hot Tune installed in ECM).
• Eliminated shift schedule offset based on steering wheel angle to give better continuity of powertrain presence.
• All new tow/haul mode scheduling for maintaining best engine speed range during trailering.
• More use of converter lockup and reduced slip rates to reduce tranny fluid heat load and improve fuel economy.
• More linear response in shifting in medium/high load.
• The shift speeds are quicker and torque response optimized.
• Positive torque requests enabled during downshifts at lower engine speeds for smoother and quicker shifts.
• Torque management maps calibrated for proper clutch control in high output applications (i.e. GDE Turbo Kit, etc), and positive torque enabled during closed throttle downshifts for improved shift comfort
• Highway passing downshifts are sharper and torque is immediate.
• Holds gear better while towing and less hunting on grades.
• Raised absolute input torque limits to enable full torque capacity of GDE Turbo Kit
• Ram vehicles now feature our GearCommand™ feature letting the (+) and (-) buttons on steering wheel to command up- and down-shifts when pressed instead of setting max allowed gear.
• Enables 2nd gear launch from a stop using wheel buttons (Ram) or steering wheel paddles (Jeep).
• Jeep Eco Mode now remembers the last mode selected instead of defaulting always to Eco Mode (for 2014-2015 vehicles)
• Jeep Eco Mode now starts in 2nd gear by default and features a shift scheduled designed for fuel economy.
