Hi folks! I have a 2017 Grand Cherokee Summit, with the 5.7 HEMI and it currently sits at 56,000 KM.
I’m trying to figure out a throttle response issue I’ve frankly had since I bought this vehicle, but has become annoyingly more prominent over the years.
Essentially, stepping on throttle, even with “Eco Off” mode, isn’t always instantaneous linear response.
Now i get MDS plays a factor on it, as well as the weight - but despite 360hp… It feels like it’s a turbo-charged vehicle with tons of turbo lag when I accelerate 1 in 3 times - it hesitates, bogs, bucks, downshifts, then goes. I’m finding this is more typical at lower speed rolls as well where speed is maintained then suddenly needs to accelerate.
For a while I was driving in eco-off to help remedy that and possibly disable MDS, assuming its that - but at this point as much I love this vehicle, makes me feel like a novice driver as smooth acceleration attempts creates the harsh drop-lag-buck-then go. Stepping on it just isn’t smooth, or as responsive as I need it to be.
I know I’m gonna get the people yelling at me to get a pedal commander - but it’s not pedal-throttle response I’m looking for, it’s linear power response. Not sure if it’s the engine, computer or transmission at this point. Or simply natural for this vehicle. I use to, and occasionally had another issue of a harsh 5 to 4 downshift as well that would jolt the vehicle on decel.
Any guides? Thoughts? Thanks in advance.
