Has anyone used a Bluetooth OBD 2 scanner paired with an android device (phone or tablet) to interrogate their RV engine and transmission. One should be able to get such things as coolant and transmission temperature out of our RV's. I have an Allison transmission and I would like to know the oil temperature of the transmission when I'm going up a steep grade. Has any one used these devices to get this and other information out of their RV computer. There's a lot of info there but how do we get to it? Anyone know the codes and procedures?

I have done it, and posted a thread about it. It works well, and looks great.

The Android app is called Torque. Ebay sellers have lots of ODB dongles for anywhere from 10 to 25 dollars. Any of them once paired and Torque set to your motor work as advertised. Torque is capable of displaying any thing your manufacturer has installed.

Ramblin,
I've noticed that you have a RV similar to mine. Are you able to read the transmission temperature of your Allison transmission?

Gee, I don't know. I didn't really get that deep into it, I just verified that it worked, and took it back out. Generally, though, if the data is available at the OBDII port, Torque can display it. If I get the chance, I'll dig it out and plug it back in to test.

Yes, there's a lot of info in those onboard computers and I'd like to know how to get to it. Scangauge2 can get to some of it but with these new devices we should be able to record and do other things with all that data.

Was informed by an Allison service tech lately that an info regarding the transmission would NOT be readable by any OBD scanner unless one has purchased the Allison software to do so...not sure who to believe, but too would like to have that info on my dash as my analog gauge is not very accurate....
