New to the wrangler club. I cant stand the throttle lag.
 
2 Attachment(s)
Just picked up my new baby and I must say I love her. BUT coming from a 1999 cable driven throttle controlled Cherokee Classic, to this new Electronic Throttle Control BS is really annoying me.

I would like to know is how to eliminate the throttle lag?
Any chip recommendations?

Also is is possible to remap the throttle back to a cable driven car? (yes I'm serious)

Be nice to the Newbie! :hide: Thanks guys!

I'm not an owner yet. But before other people reply I can say that it's normal for modern vehicles to have lag/under performance until they reach around 5,000 miles. It's a computer controlled "break-in" period.

It doesn't get any better after the break in. I had to buy a sprint throttle booster because the lag was a major issue when doing technical stuff in low range. Now the lag is gone.

So the sprint booster worked in your case? I've been reading very mixed reviews on that product.

It made a huge improvement in low range when trying to bump my way up lose ledges. With it off the jeep doesn't want to take off fast at all. With it on i have no problem spinning all 4 tires as soon as I floor it.

Haven't even fooled with it in 2h

peck1234 11-21-2012 04:24 AM

Would it be possible to mod the car back to a cable driven throttle?

WatchThis! 11-21-2012 04:30 AM

With enough coin anything is possible. But I don't have a clue.

Sprintbooster x2


First modification and love it.

Cosmic Charlie 11-21-2012 05:48 AM

That lag has been annoying me for nearly a year...push the gas and nothing happens. Sprintbooster is now on the list.

kjeeper10 11-21-2012 05:55 AM

You do get used to it someone but the lag is still there.
Think the newer Jk's are bad? The 07-09's How i understand it are the worst.
I actually lost the wir way back and its stuck on the performance setting :D

jp2611 11-21-2012 06:15 AM

not bashing...but that is part of the reason I am hesitant to "off-road" the '12 JK.....with my TJ I can shift from a forward gear to reverse quick enough that I don't get stuck if it starts to bog down (manual tranny)......there is no way I could do that in the JK (which is an Auto) Just the shifting back and forth to me feels "awkward" the way the detents are for the shifter.....I thought the "lag" was just my imagination...may have to check out the sprintboost thingy..may be first "real" mod!!!

on the street for where and how I drive the '12 it doesn't bother me....:)

Creepin__Jeeper 11-21-2012 12:15 PM

Does the sprintbooster work with the new engine and ecu? I was under the impression that it was only for the 07-11 model years, atleast thats what i see listedwhen i was researching it...

Really going to look into this. Ill keep you all updated.

calvarycoffee 11-21-2012 02:05 PM

I always thought the throttle lag was the "hill start assist" always on. I hate it too, btw.

Looks to me like it's for the 07 - 12 models. Pretty pricey though.

JKWrangler2012 11-21-2012 06:43 PM

i have owned;
2004 2.2l ecotech [throttle by cable]
2006 2.2l ecotech [throttle by wire] vehicles...
i too prefer the feel of TBC.. I've always owned manuals, and to me the difference is noticeable for sure. with TBC vehicles, i never had to rev the gas when starting from a stop... i nearly always do now. not big revs, but enough that the computer knows it's time to move.

climbing [barely] medium grade hills [off road] leaves little to be desired for me in 4hi... i'm re-gearing to 4.10's [from 3.21's] and hope this helps... i don't always like to be in 4lo.. to much finesse to get back into 2hi..

Night and day improvement for me between even my 2011 and my 2012.

Lotrat 11-21-2012 09:53 PM

I haven't noticed it with my manual. Guess I need to go stomp on it. BRB.

LudlowJKUR 11-21-2012 11:35 PM

...interesting

GregU 11-21-2012 11:52 PM

Is this an auto tranny only issue? I haven't noticed on my new manual transmission.

I have a manual and I have noticed it quite a bit

JeepHerz 11-22-2012 02:00 AM

Ok- so forgive me but I am confused.
Wouldn't a sprint booster, from what I understand, make it worse on a trail? I would think that throttle sensitivity while crawling at least- would be the last thing you want. Or are we talking more mud/heavy trail running? The website claims faster gear changes- does this seem to be true? Do the shift points change- or does it just change gears quicker?
OP- do you have 3.21 gears? They tend to shift at lower RPMs- which means you kind of have to floor it to get it going (or downshifting) sometimes. Seems like it can take forever to shift. You might be feeling a combo of throttle lag and the low gearing.
WELCOME to the forum!
(Also worth keeping an eye on- the Superchips Trail Dash will hopefully come out soon for the 2012+. They are able to re-program shift points right now- the most important thing to me. Plus all the other do-dads- but everytime they turn off the Jeep it all re-sets. Darn Chrylser security protocols. We were really happy with the Traildash on our truck. Like a Procal on steroids..... so I hope they are successful.)

2012 manual...i press the pedal even a quarter inch and the jeep imediately starts accelerating...

positrak 11-22-2012 11:53 AM

What year is that? 2011 I got rid of had it bad (auto rubicon), 2012 same vehicle does not have it at all. There is a so-called safety feature where if you do accidentaly smack the accelerator hard while off road (and on road), the lag is there to prevent it running away. You'd have to be crushing cockroaches to invoke it though.

Sprint booster worked great on my 12 Vette.

Mopar2Ya 11-22-2012 12:31 PM

I wish the tuners would release something for 3.6 so I don't spend $ on a SB to only affect the DBW. I want to change shift points more than anything.

brains 11-22-2012 12:45 PM

i've noticed a slight lag on my 2012 rubi 6 speed but only in 1st gear from a stop. the rest of the gears don't have the issue, though. accel and throttle response is good otherwise.

now, my 05 TJ, that thing was a rocketship if you wanted it to be. still, not enough of an issue for me to warrant 300 bucks on.

J GLASGO 11-24-2012 09:40 AM

I have got used to it in my 12 6-speed. I still hate the lag,and some occasions i feel like i am slipping the clutch,which is not good in the long run.I would buy the booster if it was 200.00,but 300.00 is just insane. I even called to order it once,but no answer,and no call back. It seems like the guys that have bought it are happy with it,and i am sure being able to precisely control your engine speed would help with the longevity of a clutch.

efm-7 12-20-2012 01:03 PM

Coming from a TJ with the 6-speed, I definitely notice it, and it's kind of driving me up the wall. It seems that pushing the pedal down slightly, there's nothing, and then it jumps up to 1500 and then 2000 rpm quite quickly. I'm used to engaging the clutch at 1000rpm, but I can't hit that RPM. I sat in my garage in neutral trying to see if I can keep the revs at 1000. it's almost impossible!

So really, when starting off in first, i'm doing it by "muscle timing" and praying that I don't overshoot it or worse yet, stalling.

This morning, I was trying to back into a parking spot and I stalled it.. TWICE!! how embarrassing!
