Hi, I just finished installing a Hemi in my JK. Now I want to keep an eye on all the important pressures en fluid temperatures. There are a few apps mentioned on this forum, but I don't see one that reads the oil pressure.

Is there an app (prefer ios), or a stand alone device available which connects to the OBD port and gives this information? All other sensor info is nice, but not as important than monitoring the fluids.

Thank you,

Mark Doiron

Actual oil pressure in a stock (non-Hemi) 2007 JK is not monitored. It is monitored in some later years. For a stock 2007, you just have a good/bad pressure switch, and that signal is sent to the dash warning light. If you wish to monitor oil pressure, a stock 2007 JK owner would have to add an oil pressure sending unit (but there may be one on your Hemi). It would take some very serious engineering work to get that onto the Jeep CAN bus. If it is on the Jeep CAN bus because whoever did the Hemi install did that "serious engineering work", then you'll need to contact them for the PID codes for any changes they made to the Jeep's computer. The PID codes are entered into whatever app you might use, then you custom program the app for what that PID code is monitoring. I don't know a thing about iDevice apps--but Torque Pro for Android would allow this.

I would recommend an edge insight CTS it's an expandable monitor that plugs into the obd and uses the same hardware as a superchips trail dash so there are mounts made specifically for the jk for it, if it will not monitor oil pressure out of the box you can buy a pressure sending unit and install it and monitor with the CTS

Hi Mark,

Thanks for the info. I need to change my avatar, because I recently bought a 2011 JK to put a 6.1 Hemi in, which I installed myself. I have to do a search if the Hemi has a oil temp sensor, but I assume it does.

I've heard about the Torque app, but I only have ios devices right now.

My 2014 has that in the EVIC. But you can install an aeroforce gauge in the OBDII port and it will read all that and more. It's nice to have the gauges, my wife's 2012 doesn't have them either. I also have a Hemi in mine.

I contacted Edge and asked them about the possibilities for a 2011 JK with a Hemi. They said that they have no experience with this setup and therefore don't know what can be monitored.

I'm not spending 400$ for a couple of gauges if I'm not sure they work on my JK.
