JKU Wrangler Throttle Response

Phoenix Rising · Post by **Phoenix Rising** » Mon Feb 16, 2015 8:07 am

For all you Jeepers out there, I am trying to gather information regarding improving throttle response on my 2014 JKU. I am interested to know how I can improve it. There are a number of programmers/tuners out there but want to know your opinions on what is considered the best. Diablo, Bully Dog, Superchips, AEV Procal etc etc. What about a throttle body spacer, will that help?

I look forward to hearing your opinions. Thanks in anticipation.

The spacer will help

It is a drive by wire system!

The lag is "programmed" into the Jeep pcm to be easy on the clutch or torque converter ... but there is help:

Hi SSS,
So with a body throtle spacer and the sprint booster you should get a better performance out of a JK2014?
Do you have it installed yourself?
Cheers

I always ask myself, if all it takes to boost power is 1/2 inch of aluminium plate with a hole in it, then why didn't the manufacturer put it on as stock?

Highly skeptical.

Agree - was recommended to install one by Triplod (Overseas Marshall) and have one lying which I have been hesitant to install as it looks like there is very little space for the cool air intake.

However, Triplod's comment was that he at least could see improvement on fuel consumption due to the centrifugal effect the throttle body spacers allegedly creates.

It's a conspiracy with the oil companies!.... ha ha. They don't want you to KNOW.

It'll only help to lighten your wallet on most vehicles, while it might actually produce a small performance/mpg gain on a few.
A well-designed cold air intake (one that actually sucks in cooler ambient air and not hot air from under the hood) can improve throttle response by removing the main "choke" points of a stock intake (usually the snorkel to the airbox and the pipe from airbox to throttle body).
The stock ECU tune is usually conservative in order to cope with poor quality fuels so if you like to run your engine on higher octane fuel, a custom ECU tune with revised fuel/timing maps will sharpen throttle response and add a few HP. Note I said CUSTOM tune, not an out-of-the box generic tuner.

I was trying to politely say "TB spacer is useless" in fuel injected cars!
All you do is you increase the pure air way ... and it does not matter much if you do that before the TB butterfly valve (e.g. longer air intake tube or snorkel) or after the butterfly valve (spacer).
If you had a TBI (throttle body injection, like some old chevy engines pre 98) and you increase the air way (volume!) for the MIXTURE with a TB spacer, THEN you might find some significant torque and response increase!

Sprint booster on a 4.0 TJ ? no ... and not even on my current LS1 TJ with GM pcm (where you can program every aspect you can imagine with a laptop and a nice software like HPtuner or EFIlive)

But Hani/AnTrax liked the sprint booster for the old JK at some point long time ago

Sorry Abu Al3bed ... but I have not looked much at Nissan Patrol tuning ... no clue at all. But I think the most poular mods start with headers and cam and some unichip (or motech) EFI engine management upgrade. It goes over stroking and charging/blowing ...
As far as I know nothing much bolt on and cheap ...

My understanding is that for you to be able to enjoy the benefits of the centrifugal effect the TB spacers creates it would need to be considerably longer (Someone was doing the numbers on one of the forums I was crawling and mentioned that it would need to be close to 1m). Another plug-and-play gimmick i'm afraid. Unfortunately, one which I had fallen for and wouldn't do again.
