I don’t know where you are. I couldn’t tell from your info. So you are on your own. But this kind of issues, I believe this community could really help each other. I say I have 0 issues with my Jeep. If your dealer says something that annoys you is normal “Jeep thing” you should drive on of ours that see no issue to really determine if it indeed is a “Jeep thing”.

The throttle response in these are awful.

My description of what I am experiencing with the bad oem tune mirrors that of many others on this site. There is nothing a dealer can do until FCA writes a new tune (mark my words) for the 2020 model.

How’s mine different?

My PC arrived a couple of days ago, go it installed and WOW what a difference, I’m using it in City -2 and the throttle feels the way it should from factory. I know it only changes the throttle input but the ECU keeps relearning our driving habits and the PC will definitely make the ECU learn a pattern for a more responsive throttle and shift points. Definitely recommended!!

Could you please send a link to the PC you got? Thanks

We took it to our dealer we originally purchased from. And like always we drove with him and it drove normal no studder. He did hook it up and flash all updates. It did help with the throttle hang but the studder is still there but slightly less. We will keep watching it and see if we can reproduce for the dealer if it happens more often.

Do you know what Flash updates they did? I have to get this throttle hang fixed. It’s killing me.

Hate this to be my first post, but wanted to ask the forum. I am having similar issues to this (6 spd MT) lugging/surging at constant RPM. I brought it in to the dealer, they reflashed everything, and I'm still having the issue. One of the other weird things I have noticed is that if I clutch in at speed, the RPMs hang around 1200 and drop to idle when I stop. They also sometimes drop to idle for a second and then rev back to ~1200 and hang there. This I can see on the tach and also feel in the clutch pedal. Dealer claimed they didn't see anything wrong. Thoughts?

Oem tune my man, oem tune (I say this while I shake my head.)

It’s frustrating, I know. Not even sure why they messed with anything from the JK tune.

Mine behaves similarly. If I push the clutch in and slip it into neutral, the RPM will spike when I let the clutch out even though I'm not touching the accelerator. Constant low RPM in 1st gear also bucks. It's OK if you're completely off the accelerator or accelerating, but not at constant speed below 2000 RPM.

I agree, the OEM tune is bad. I'm hoping an update will come out. If not, I'll go aftermarket when available.

Went back to the dealer today and was told that yup, this is normal. Manager said I was "lugging" the transmission, even in 3rd at 2k RPM (Concerning that it's lugging at that RPM). As you guys have said, very frustrating and I hope Jeep comes out with a different tune to fix this.
