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.

Our customers tell the story about the trans tune better than we can. Below is a write-up of the ECODIESEL trans one the WK2.

Eco Mode - actually fits its name now, the fuel mileage goes up before your eyes. Always starts in 2nd and though it’s tuned for economy the shifts are much smoother with less hesitation than stock.

Normal Mode - feels similar to the stock sport mode shift map. Power is there when you need it, shifts are crisper and the fuel mileage is the same or better than the stock eco mode map. I use this mode most often.

Sport mode - holy balls! The truck squats, shits and gits ???? it’s like doing a hole shot! Lmao it woke the truck up so much it’s insane. The turbo whistle is louder in this map (keep in mind I have other modifications) and the torque is instant. Shifts are so fast you don’t even realize they happened and the majority of differences are noted at slower speeds. (I.e. if you peg it at 75-80 you don’t see much of a difference). If you’re around 30% (estimate) throttle at those speeds the truck takes off and scoots. This mode is jumpy in stop and go traffic mostly because you catch it in between shifts at super slow speeds. Doesn’t happen often but every once in awhile you’ll catch it in the middle of shifting and the truck will buck.

Everything is much crisper and smoother, the truck is WAY more responsive, definitely quicker in all regards, and fuel economy is drastically improved in all modes. Compliments the GDE tune perfectly! The device you get also doubles as a code reader and diagnostic tool which is pretty sweet also.
