My 2012 JKU (3.6 / auto & 3.73 gears) has only 200 miles on it so far.
I realized from day 1 that there's a lag between pressing the accelerator pedal and actual engine response.
Up to 2010 models this was easily curable by increasing the throttle signal strength via most popular handheld tuners.

Is this possible to do with the Procal ?
Or are there any other solutions ?

 

Sprint booster pedal improver. Has 3settings and connects between pedal and computer connector. To my knowledge it works on all years from 07- up

 

no mention of 2012 ... I emailed them

 

I recently installed one on my 2011 and it works great. Worth every penny,

 

Is your 2011 auto or stick? 4.10? Did it improve the downshift out of OD?

 

I believe the 2011 and 2012 are the same part # (not the same as 2007 to 2010) see here:

I have a 2011 JKUR Auto - works great - but no change in downshift out of OD. I just ordered a 2012 and will install my current SB in it.

 

It does work the same in all years, but 2007-2010 are a different fit and model # than the 2011+, which are shaped a bit different.

 

I stand corrected, from sprintbooster:

" Effective May 1st 2011, all JK & KK 2007 - 2011 Sprint Booster will come in this new “flexible body” design. The part number will remain the same since programming of the unit remains identical to the preceding version. "

So JK boosters made prior to May 2011 will not fit 2011+, newer boosters will fit all years. Details here:

Welcome to drive by wire. Every car has it now and damn near every car has lag...some worse than others. eventually someone will make one for the new 3.6 My buddy who has had like 9 jeeps drove mine yesterday and he said WOW that will take some getting used to. i just laughed and said yes it does.
