Soon complete TFT 7" Dash for all gauges and switchs
I am working on my project for my car. It's 7" LCD tft with arduino to read all OBD2 pids from LS1 ecu and show it on the screen.
I used Arduino Mega 2560 with 7" LCD touch screen to show gauges and control the Boost and another features.
I will update the this post with my updates
What I added to read:

What I added to read:
- RPM
- Speed
- IAT
- ECT
- Timing
- MAP
- Boost
- MAF
- AFR through analog
- Check Engine
What I will control:
- Boost
- Meth Injector
- Engine Cut off for saftey

This post in 18 months old, theres a good chance he isn't around anymore.
If you want to be able to read an OEM PCM with an arduino, look up OBDuino. It will get you started.

My 7" screen will do PWM boost control, 2 and 3 step, trans brake control, boost based traction control, read VSS, VR ABS sensors, multi-stage nitrous control, progressive nitrous control, methanol pump control, progressive meth pump, 2nd fuel pump, PWM fuel pump and fan control, take input from 100 PSI fuel oil and whatever other pressure sensors I want, GPS input, paddle shifter input/output, 8-channel EGT/backpressure, and things that even the high-end aftermarket ECMs can't do, all while sending data back to my megasquirt to be logged alongside everything it is already logging.
Arduino is quite a bit more capable than plugging in your spare walmart tablet so you can have some gauges.

Because your screen can't control 50+ outputs, relays, PWM, take input logic from VR circuits, dozens of 5v inputs, square wave and sine wave inputs, communicate with aftermarket and OEM PCMs via CAN BUS, and so much more...

Reading OBD isn't that difficult with an arduino. There are sketches out there that you can download to do it with minimum programming required.
If he just wants digital gauges, then yeah, tablet is better. If you want to do anything with that data, arduino all of the way.

Are you guys using generic OBD2 to read the pids, or GM-specific extensions to OBD2?
And, how many parameters can you read per second?
