I do have torque and an odb reader and never use it. <BR>

Scanguage IIs also can calibrate to your fuel injection system and keep track of your fuel consumption, such that they can predict exactly how many miles you have left before empty. (basically by counting number and length of each fuel injection pulse) In the truck, which shows empty when there are 6 gallons left, this is helpful for planning gas stops accurately. Especially when you have to find USLD instead of gasoline. <BR>
<BR>
I don't recall other Android ODB software doing that in a way that I'd trust. <BR>

I really think the 4 button Scanguage is the way to go. Dorking around with the UI on an Android device while driving is just too distracting. <BR>

Hi all,
I'm trying to find a good way to add obd based instrumentation to my
car. The scangauge product is an obvious choice, but they want $ 160
for the 4 sensor display model. I thought I was going to use a 7"
tablet, but that's just a bit too big, and I really have no good place
to mount it. I'm thinking I could get away with a 5" tablet and mount
it under my gps (also 5") in the center of the windshield. However, 5"
tablets are almost impossible to find. So, I wanted to see what you
think. A phone could work if and only if it can operate without a cell
phone contract or account. If the total parts count ends up over about
$ 130, I'll just go with a scangauge. I know I'll have to add an obd-II
- USB cable from amazon for $ 20 - 30. I want a wired solution rather
than a wireless solution for security reasons, since the obd-II adapter
will be permanently in place.
I've tried the following websites searching for tablets: TigerDirect,
NewEgg, Micro Center, DealExtreme, ChinaVasion.
Here's what I need:
Required Items:
* 4" - 5" tablet / phone - required
* OS: Android 4 or better - required
* Google Apps, Play, etc. - required
* Screen: capacitive multi touch - required
* USB: with OTG Capability - required
* USB Adapter: Micro to Standard - probably required
* Memory Card Slot - required
* WiFi Radio - required
* Lack of Memory Flaw - required - All of internal flash memory after OS
must be available for user apps and data. Not partitioned as in 1 GB /
3 GB.
* 512 MB RAM or Better, 4 GB Flash or Better - required
* Windshield Mounting System - required
* External Power Adapter & Port - required
Powering through usb would be a problem unless the obd port can
provide enough power, which I doubt. The obd-II - USB cable may not
provide any power to the tablet at all. Also, the obd port remains
powered after the car is turned off, which could drain the car's battery
if powering the tablet.
Optional Items:
* Bluetooth - desired
* Gravity Sensor - desired
* Accelerometer - desired
* GPS - desired
* 3G / 4G / Cellular Radio - optional - If present, must be compatible
with Verizon and the rest of tablet / phone must be able to work without
a cellular account or contract via wifi only.
Any thoughts? On the chance any of you wanted to sell me used
equipment, I would have to get the obd-II adapter and confirm successful
operation before finalizing a purchase. I would also have to find
viable solutions for providing power in the car and mounting the device
on the windshield.
Any help is always appreciated.
Sincerely,
Ron
