It's not about breaking the code. It's more about making a custom PCM work on the 2011. I have a custom PCM that you swap out with your factory one and your good to go. I can also make you a custom tune for your supercharger setup.

@ jaimeson55 I have 2011's running our supercharger and ecu tuned with a diablo predator.

I have ECU's that will allow you to use a predator on a 2011 jeep wrangler. message me for more info.

2005-2006 wrangler 4.0
2007-2010 wrangler 3.8

We have several custom tunes aviable for the jeep JK. I personaly tow a 12ft enclosed trailer with my 07 Jk and have a custom tune made for it. check out or site www dot hesco dot us

we also offer a offroad and econ tune

are you sure the custom tune is really a custom tune? post up your original tune and custom tune and we will have a look at it.

if you didn't get the original file loaded onto the predator correctly when you sent the custom tune to the predator it will show that the tune was loaded properly into ...

Well I'm still getting the P0440 and P0441 with all the canned tunes. Everything ok when running the stock or modified stock(15% throttle boost). Last wriiten tune is a couple of pages back. Do like the mpg boost tune until the ck engine light comes on.

I see it all the time on JK's...jeep put ...

call Steve at rdpmotorsports. He really knows his boosted mopars. Tell him Jon from HESCO sent ya

where are you loacted?
I would find a CRM tuner in your area and get it properly tuned, Mail order tunes are very hard to get right when you have that many mods.

you have to be sure the original tune is loaded into the predator correctly. When you "send tune file to predator" it will ask you to browse for your original tune file, you MUST navigate to the area where you saved the original tune file and double click on it....if you let the software load it ...

the tunes are basically the difference in the timing added over stock. the higher octane fuel you run the more timing you can run without it pinging....more timing= more power

I think you are thinking backwards. 10:1 is richer than 12:1

if you were running 10:1 at diablo settings and added fuel in the tune then you would go richer IE.. 9:1
9 parts air to 1 part fuel....... 14:1 is 14 parts air to 1 part fuel.

also if your not dataloging the wide band you won't be able ...
