(Hello, I did a quick search of the forum and couldn't find this subject matter but if it's previously been covered, would someone share of link?

I have a 2015 JK Rubicon Unlimited and would like to modify the ECU settings for the following items:
* change the temp that the radiator fans come on. It's currently set at 228 degrees.
* activate rear locker in 2wd and 4H
* Sway bar disconnect in 4H
* remove stability control (DSC) in 2wd and 4H
* turn off ABS

I was looking at programmers and most want you to exchange the ecu. Is this the equivalent of a 'jailbreak'? They're also about $800.

Does anyone have experience with OBDLink MX+ with the AlfaOBD App? This seems like a very inexpensive way to modify ecu settings. Would this work with the 2015 ECU?

Any help or experiences would be appreciated.

Thank you!

 

All I know is you may have to unlock your ECU which started in 2015 sometime. I use HP Tuners which does not cover all the Jeep things you want to do. The engine temps it does but you also failed to say if you will use a lower temp thermostat which you will have to. Other than that one and the ESC stuff JScan should help with the locker and SB disconnect.

 

Awesome! Thank you very much for this information. Cheers.

 

HP Tuners menu for a 2008 Jeep temperature control is like this and many variables to change.
