Im trying to find an electrical gremlin and was wondering if anyones used this one and do they display sensor values

 

Since you didn't give your year, I'm going to assume you have an OBDII vehicle. I'm also going to assume you have an Android device, since that thing won't work with an iPhone.

That exact adapter was the first one I bought. It worked flawlessly for me with Torque on a Galaxy Note and a Galaxy S4. I suggest you go ahead and shell out the $6 for Torque Pro, but Torque Lite will work fine with it also. Torque Pro will read and reset codes, and in real-time mode you can monitor pretty much any data the computer gets from a sensor. You set the output up as virtual gauges on your device.

I run mine 100% of the time in my Subaru and as needed in the Cherokee. Eventually I'll run it 100% in the Cherokee also, once I get around to setting up a dedicated device for it like I have in the Subaru. Here's an old pic of mine in the Subaru (I have added more gauges on that page since then):



You get several pages you can put gauges on. It will also give you emissions readiness:



If you buy one, DO NOT install any of the software on the CD on a laptop. The software that comes with these Chinese and Korean BT adapters is rife with malware. It's not that they're trying to infect your machine, but they get cracked software off of warez sites on the internet rather than paying for licensed copies, and it's already infected when they download it. You don't need any of that crap anyway if you're running Torque on a phone or tablet.

You also need to know that the BT adapter draws power from the OBDII connection, even when the car is turned off. It's usually not enough to kill your battery overnight unless you have a charging problem, but you don't want to leave it in there if you have a weak battery or plan to leave the Jeep sitting for more than a day or so. I actually upgraded to a ScanTool OBDLink LX because it has an auto-off function to save the battery, so I never have to remove it. But that BAFX adapter works fine for a lot less money.

 

Awesome teply i just answered everything i asked and my xj is a 99

 

where do you buy the OBD II connector?

 

That is so cool. If only I could do that on my Renix

 

A better idea is a Scan-Gauge it gives you everything in a dedicated package I run 2 of them in each of my Jeeps. Cheap easy to use and comes with the connectors. You can customize each screen to show what you want it to and in what order, covers all OBDII functions available to your XJ. Mine is shown in a factory Scan-Gauge mount (optional).

 

There was an address in the first post, but it didn't turn into a link. Here it is again:



Note there are some others that are even cheaper and work just as well. Just search for "Bluetooth OBDII" on eBay and Amazon for those. You'll want to read the reviews to make sure you're getting one that is reliable.

What will the ScanGauge do that Torque won't?

Also,

ScanGauge = $95

Torque + BT Adapter = $30

I don't think I would consider the ScanGauge "cheap."

 

You can search on aliexpress for elm327 and find them for $7.48 with free shipping.
I have an older one that has worked just fine with several vehicles, phones and tablets and laptops.
The real key to these things is the software and the best I have tried with Android is Torque, the Lite/free version has worked fine for my meagre requirements. I stop trying Windows versions on my laptop after I found Torque.
Read a code and Torque will let you look it up so long as you are connected to the net.
