I seriously considered going back to a gasoline Chevy. At least the settlement resulted in a payment. May 2019 – July 2020 - Frustrated warranty work required all recalls to be performed prior to completing warranty work. It seems apparent GDE tested it on the road prior to my purchase.įeb 2017 – May 2019 - I liked my EcoDiesel and didn’t regret switching to RAM simply for the engine. It is a relatively new release, but after installing I am pretty sure this tune was set up by people that have been in the drivers seat.

Thanks GDE! The install didn’t result in a single busted knuckle nor dirt under the finger nails. Enables 2nd gear launch from a stop using wheel buttons (Ram).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.Holds gear better while towing and less hunting on grades.Highway passing downshifts are sharper and torque is immediate.Positive torque requests enabled during downshifts at lower engine speeds for smoother and quicker shifts.The shift speeds are quicker and torque response optimized.More linear response in shifting in medium/high load.More use of converter lockup and reduced slip rates to reduce tranny fluid heat load and improve fuel economy.All new tow/haul mode scheduling for maintaining best engine speed range during trailering.Eliminated shift schedule offset based on steering wheel angle to give better continuity of powertrain presence.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).1-2 gears lower compared to normal shift maps) Revamped warm-up mode scheduling to provide faster engine warmup (i.e.Refinement on shift scheduling in altitude to provide better engine responsiveness.Hill mode optimization to prevent gear hunting.Downshift criteria revamped to best utilize engine torque curve and stay in each gear longer.Upshifts earlier in all conditions for improved fuel economy.Eliminates 2-1 downshift hesitation at low speed tip-in maneuvers (i.e.
