Torque Pro + Android tablet as digital readout?

The short answer is yes.

The longer answer is I would NOT trust a window mount in a race car, and the Lemons guys I've seen in the past don't allow go-pro window mounts so I'm sure they will have a hard time with an Android window mount.  IMHO it should be securely mounted where your gauge cluster is or in some other place, securely and permanently. 

Second, regarding those touch tip gloves you would need to sew the tips on with conductive thread.  Modifying your flame retardant gloves like that (which should ONLY be sewn into with nomex thread) to use a gauge cluster that would be distracting to the driver is a really bad idea.

Basically install it safely and securely where the drive can see it, determine a best gauge setting, and leave it alone.

I've used a suction cup mount in every race i've been to. It's a huge RAM Mount that came with my Contour Camera. I use it to hold the cell phone that does my live streaming. I do however tether the whole thing to the roll bar just in case something happens to prevent it becoming a missile. I do think I could hang from that mount however. Better than suction cup mounts are roll bar mounts. They tend to let go less often.

I've used torque in my daily driver. It's a little slow to update you certainly don't want to use it as a tach. But for general temperatures, it's fine. I don't know why you're concerned about trouble codes when driving. You do not want to be fiddling with things while driving.

Do not put it where the drive can't fiddle with it. If you're going to use it, mount it where it's visible, and just leave it as a display.

Also Obligatory: Your car has OBDII? Too new.

Ok. Message received. My drivers will not get to play with the tablet, I will not modify their gloves. That is a bad idea.

A little backstory, me and a fraternity brother bought a Cook County (Chicago) former-K9 P71 2003 Crown Victoria. We're hoping to race in October, but I just graduated and I'll be moving to NYC to work in less than a month. Can't turn wrenches from NYC! What I can work on is a sweet instrumentation setup for the car (the biggest thing being the lack of tach).

I'm a computer engineer, so my response is "Doesn't have a computer running it? Barbaric!"

I do want to make that. How can I get in contact with him?

Olaaf has stepped away from racing for awhile, as other opportunities have opened up for him and he has been doing some global travelling.

Olaaf is also a very talented driver, and even he had all those readouts color-coded so he could take just a quick glance to see if there were any issues.  I have no idea of your experience or talent, so please do not take this as a slight to you.  Quite honestly, that would be more than I would ever be able to take in.

Like The Engineer said, tach, water temp, and oil pressure will be enough to keep you informed of the general happiness of the engine, plus is about the most amont of info that an inexperienced driver can absorb.

The other problem you'll face using an OBDII Bluetooth device is the reconnection of the Android Device and the OBDII device over bluetooth. 

Because you are killing all power to your car each time you pit, you'll find that the reconnection (and getting the requisite software online again) is much more difficult than you think.  I've tried something like this and it was an abysmal failure.

In my case it wasn't the adaptor.  It was the software reconnecting and reading the OBDII information again in real time.

Edited for brevity.
