Hello guys and gals. I'm new on here and looking for some help. I am trying to find a stock tune file for 96 or newer xj 4.0.
I have been working on a project jeep off and on for several years... I did an engine swap to an upgraded engine I built, but I was still really ignorant as to how everything worked and proper practices and long story short I never got a baseline tune file for the 4.0 before changing everything....

So again, to make a long story short... I am interested in tune files for the jeep I6 4.0... the file I am interested in the most is that of a Stock 4.0 in properly functioning condition. Other than that I am also interest in any tunes with modest upgrades and tuning adjustments... I understand that I need to tune MY engine and sombody else's tune won't be the best fit for mine, but I would like to have them to compare.

Any help is MUCH appreciated.

 

What engine management system are you using?

 

I'm running a stock JTECH computer.

 

What tuning module are you using, HPT?

 

Yea I am using HP tuners MPVI2. I have the prolink hardware coming in mail, when that arrives I will be able to properly connect my AFR wideband... and I believe at that point all I will need is the file to start building off of... unless I am forgetting a step somewhere... but that is yet another bridge... I'm learning as I go... 😃

 

I'll take a look. Also don't flash a 97-99 cal onto a 96.
