Why does JT have poor throttle response?

[Duece McCracken]

Tuning would increase response, but there goes your warranty.

A hardware solution would change accelerator pedal to TB correlation. Also be more easily reversed.

I was looking into this a bit. Found a company that ports the OEM intake manifold and offers some OEM V8 TB conversion. Which by itself may improve response a fair amount, but most likely tuning would be needed to see the most out of the parts. Also its like 1200 in parts iirc. Maybe more, lol

As stated above, better response can be a negative on certain terrain. I'd rather has the response and learn how to drive it, then have a computer neuter it.

Different strokes for different folks.

I've been driving mine conservatively for a couple of weeks now. Holding higher gears in manual mode and being easy on the pedal.
Really just experimenting to see what kind of mpg I could get by driving in "no big hurry" mode.
Yesterday I got behind one that was trying my patience and I broke out of my shell and punched it.
To be honest, the damned thing caught me a bit off guard and took off like a rocket.
I don't know, but I've heard that the system somehow learns your driving habits over time. So maybe I caught it by surprise and it was ready to give me what I've been saving up?

Anyway, my average didn't suffer much and I'm still around 19.4, which isn't bad for 2" lifted Mojave on 35's.
Overall, I've found little need to increase throttle response.. When I need it delivers all I need.

Ah you have one of the JT with the special good motors

Maybe I do.
The first two oil tests have been good and it's rubbing great now. I did have a misfire issue early on, but it was corrected by either a software update, some plug and coil pack swaps, or both.
My MPG did seem to drop slightly after the second PCM flash, but I'm hoping that's just winter blend.

Hopefully it stays good for you. Its always interesting to see all the different results people get. I would love to get that kind of gas mileage out of mine but would likely have to return to the stock tires to see it. The throttle response on mine was terrible as well. I had to put one of the throttle controllers on it but I don't run it on any of the aggressive modes just kind of the middle ground and it has made a big improvement.

How are some of you getting this kind of mileage? I get about 13 on 35s and 2" lift and even regeared it to get back 7th and 8th. I do drive only city usually though..

Im teraflex 1.5" level spacer, OEM wildpeaks, RR arcus bumper, Badlands Apex winch.

Manual trans, 15 mpg mostly highway. I can get 18 avg on long drives, sometimes a squeak more if I drive super boring and slow.

I'm with you, lol

Since you keep mentioning that it's only an issue for manual transmissions, and bring up time between shifts, I have to ask. Are you referring to the response time for the pedal itself when you depress it? Or are you talking about the rev hang response time when you engage the clutch? Because those are two very different things.

The pedal response time is going to be the same or similar regardless of transmission. This is why you're getting responses from people running automatics and the pedal add-ons they're using to change how the pedal reacts.

The rev hang response time is what's truly a manual-only thing, and that's a common thing for all MT vehicles to have. There's a variety of reasons for it, from efficiency to longevity, but it should only be an issue if you're trying to fly through the gears like a racecar.

And lastly, when you say "ESS" I'm assuming this isn't the electronic start/stop system you're referring to. Are you talking about the "ESC" electronic stability control instead? If so, that will really only show it's face if you lose traction. It's obvious and abrupt when it engages, and a light on the dash goes on (blinks if I remember right). But when that's happening, pedal response isn't a thing anymore as it's being overridden, so I don't think that has anything to do with what you're talking about. With that off, it will respond the same as any other Gladiator, manual or automatic.

ESC is what I meant. Really the #1 issue is slow response when letting off. This this is a hoot offroad
but with ESC off you really need crisp throttle to take advantage of the chassis (Mojave) and its just not there. Its detracting from an otherwise excellent platform.

Id like ESC off to cancel the rev hang and switch to sport throttle response. Makes sense right?
Jeep, give us a full sport mode to match this chassis!

Not snapping the throttle (plate) closed at higher RPM and rev hang are all related. Chrysler and most of the OEMs have tuned it to do that for emissions purposes.

Livernois has a tune for us manual drivers that will force the throttle plate to follow the pedal.
They said if you jump off the gas in third gear it will bark the back tires on decel.

Really, that is the right type of solution approach.

It does ok for autos. The MT just needs faster response. Shut off ESS on gravel and let me know your thoughts. I find its like driving an early 80s turbo.

I bought one off of Amazon, I also have an MT. As soon as I started the jeep, I had all types of errors and lights flashing on the screen. It was promptly returned. But I can definitely see where it would benefit the MTs.

 

[Drink_to_the_Foam]

I know it is a different platform but I had a 2007 Jeep MT that had horrible throttle response and actually made me not want to take it off road. I put a pedal commander inline and it changed the personality of the Jeep completely. In the sport + mode it was nearly impossible not to break the tire loose. I am not sure how it would change a Gladiator but that little box was a game changer with the dog 3.8l.

A friend of mine tried one of the cheap Amazon ones and it caused him nothing but trouble.

I got the Hikeit and my Mojave (auto) drives like I feel it should. I accidentally turned it off recently and I felt like I lost 50hp lol.

 

[Drink_to_the_Foam]

The pedal commander and Hikeit are comparable products. I am just telling everyone my experience. And that was on a 2007 Wrangler. I am sure the Hikeit kits are good too. Personally I would pick which ever is made in the USA.

The stock throttle response on the JT 3.6 is one of the worst of any car/truck I’ve experienced. The Banks Pedal Monster solved that issue 100% for me and makes the driving experience a ton better. Almost to the point where I don’t notice the weak HP figure on the 3.6.

I don’t know if these throttle controllers make a big difference on most vehicles but it sure does on the JT 3.6. You won’t regret buying one 1 iota.

+1 on the Banks Pedal Monster. Makes a huge difference.

That'll do it, city driving. I get 12 mpg on stock rubi tires and no lift. Stop and go all the way to work and back. Once I hit the highway I see 19-20.
