Okay, so I just got this:
Super Mini Small ELM327 V1.5 OBD2 OBDII Bluetooth Adapter Scanner TORQUE ANDROID | eBay

And this:
Torque — OBD2 Performance and Diagnostics for your Vehicle

And now I want to display individual tire pressure, if possible. Does anybody know the PIDs for this data?

Regarding the adapter, it's so small it barely protrudes out of the dash. It's a bit fidly to get it to connect. The car BT was fighting with it, until I told it not to connect to the phone. Also, when I re-connect it takes a bit of time. But generally seems to work. The Torque app is awesome, to. If only for the 0-60 times, it's worth the $5 plus $25 for adapter.

 

Not sure about the PIDs but now I want to get this setup.

 

I been using this for many years. Same setup as yours just my adaptor is the longer , older version. The only complaint is the initial connection as it sometimes takes forever or wont connect. Make sure you go through those settings menus good as there is a few settings that can make it respond faster as default seems to be a bit laggy.

 

Bigcat,

My '11 Premium is supposed to put out 385 HP at the crank. So far, I've yet to get more than about 250 at the rear wheel according to Torque Pro. I know losses are to be expected, but 35% is more loss than I was expecting.

What's your experience with HP readings in TorquePro?

 

This peak rated horsepower number is only achieved at peak hp rpm. Without a dyno brake measuring actual whp, and an accurate algorithm to reverse engineer the crank power needed to yield that whpnumber, I don't see how the accelerometer type device could ever calculate this number accurately since you only see it at full throttle, full boost and the specified rpm which will be around 5,000 rpm or so for a supercharged engine.

 

I am thinking about purchasing a diagnostic tool for my XF. For the last 10 years I have been using Ross-Tech VAG-COM (Ross-Tech: VCDS) on my Audis. Its a pretty useful tool that allows you to data log; scan codes and clear codes; and code some modules using the cable/software program and your laptop.

Is the system described above the equivalent for Jaguar's? Is there a better more powerful tool? Do people prefer the bluetooth/phone over corded laptop? Do each have the same capabilities? Finally, can I code the TPMS using any of these tools? Thanks in advance and sorry for all of the questions.

 

I've been looking for Jag PIDS that can be used for monitoring since I got the same setup, but haven't made any progress. I did find this site, but it seems to be all error codes, uncategorized in any way:

Error Code Manufacturer Listing

 

I bought this bluetooth OBDII adapter the other day. Works great for me. After you pair it for the first time it connects every time on it's own. I have the free torque app now but I might spring for the $5 version.

 

Bump

Sorry to resurect, but I've been looking for an answer to this question, too. The VAG-COM lets you reprogram almost all your codes and factory settings, while these OBD-II scanners and apps mostly seem to just monitor things and reset error codes. Can't seem to find a VAG-COM equivalent for the Jag. Any new info out there?

 

IIRC, the jag specific tool was listed in tue classified section a few days ago.

 

Good Jag dealer-level tool is Mongoose JLR.

The lawmakers for OBD only did basic emissions stuff so tyre pressure PIDs are not public data

Pity they let auto makers hide all the stuff everyone has a fair reason to know. Lobby representatives to change law?
