Hi Neal, and others,<br>
<br>
I finally got my Bluetooth OBD scanner, and have been having a ball
playing with it. I'm going to share my experience with everyone.
Regarding distractions, I agree with you, so let's get the warnings out
of the way.<br>
<br>
Warning - Do not try this, as it can kill you! OK, some of you will
try it anyway. I'll show you how.<br>
<br>
Actually, really, seriously, you NEED to heed the following.<br>
<br>
Warning - The best way to use this application is to have someone else
drive and you tinker with the phone / tablet (henceforth referred to as
tablet).<br>
<br>
Warning - Preset the gauges you want on the screen before you start
driving.<br>
Warning - If you have the tablet in your view, make sure it is securely
mounted.<br>
Warning - Do not touch the tablet while the car is moving. If you do
touch the tablet, do it while the car is stopped and will remain
stopped long enough for you to finish what you're doing.<br>
Warning - If you look over at the tablet, do so for only a second or so
when not near cars or people or animals or inanimate objects.<br>
<br>
This thing has an almost magnetic pull on your hand to tap the screen
to do things. Fight it. I went out planning to follow these rules
from the start. I made a tiny, short, exception, looked at and touched
the screen for the briefest period of time, and ended up getting
annoyingly close to someone's rear bumper. Thankfully, his car and
mine never touched.<br>
<br>
Before you ask, I did capture the full instrument panel screen shots
while driving at very slow speed in my neighborhood with nobody
around. Other than that, I secured the thing on my dash to my GPS
mounting bracket, and let it be.<br>
<br>
Regarding clearing check engine lights, etc. If you clear a fault like
that, it takes about 100 miles for the car's computer to complete it's
cycle and declare that it's happy. Prior to that time, you cannot pass
emissions, for example. If the fault stays gone, then you could pass
the emissions test. If the fault indication returns, you'll probably
just have to fix the problem to pass the emissions test.<br>
<br>
OK, enough of that. I totally love this product. It is great fun, and
very informative. I'm going to share my experience here in case anyone
else want to try it. I now have two new virtual instrument clusters
that I can display on my tablet, one with 15 items, and one with 19
items.<br>
<br>

<br>
Here's what you need to make this work:<br>
<br>
1) Android phone / tablet with Android 1.5 (I think) or above,
Bluetooth, GPS, and wifi<br>
2) The Torque Pro Android application to read the car's Engine Control
Computer. I think there's a free version with ads. I got the Pro
version for, get this, $ 5, in order to support the developer and
eliminate any possible ads. There may be other programs to do this too.<br>
3) A Bluetooth OBD II adapter which plugs into your car's diagnostic
port. I think the application can use wifi or USB adapters, but
haven't tried this.<br>
<br>
Here's the Bluetooth adapter that I purchased. I cannot speak to
longevity, but, so far, it's working fine. It was $ 24 with free
shipping. It's dimensions are about 3" x 2" x 1", and it plugs into
the port under the dash near your feet. In my case, the adapter
continues to draw power even after you remove the ignition key. You
might not want it to stay plugged in when you're away. Also, it could
potentially allow someone else to link to your car's computer if
they're close by. I have to study up on bluetooth security. I've
confirmed that my tablet can read the car when I'm 30' away from it.
This adapter came with software to run on the PC. I haven't tried that
yet.<br>
<br>

BAFX Products (TM) - Bluetooth OBD2 scan tool - For check engine light
and other diagnostics - Android compatible<br>
<br>
Here's how to get all the pieces working. By the way, I'm sorry some
of the photographs I'm showing are fuzzy. My camera really didn't like
to focus on the tablet screen.<br>
<br>
Buy Torque Pro from the Google Play Market (or try the free one),
download it, and install it on your Android device.<br>
<br>
Get a Bluetooth OBD II adapter. Some work well. Some don't. Some
work with some cars and not others. Some units may work slightly
differently. All I know is that this adapter is working with my 2002
Toyota Camry and my wife's 2007 Hyundai Sonata. Plug the adapter into
the port under the car's dash near your feet. Make sure it's facing to
match the keyed connector. On my Toyota, it's label toward the
driver. On my wife's Hyundai, it's label away from the driver. Don't
hit it with your feet. I haven't tried reading / clearing any fault
codes yet.<br>
<br>

<br>
Turn the car's ignition switch to the accessory position but don't
start the car. The power light on the adapter should come on if it's
not already on.<br>
<br>

<br>
Go to the bluetooth setup screen on your tablet under settings and tap
search for devices. This is Android 4, Ice Cream Sandwich. Other
versions may work differently.<br>
<br>

<br>
This particular device shows up as CBT. Tap it to pair with it. Based
on my reading, some Android devices may say paired but not connected
when done. This is OK.<br>
<br>
<a href="http://dl.dropbox.com/u/9879631/OBD04%20CBT%20bluetooth%20device.JPG" target="_blank">http://dl.dropbox.com/u/9879631/OBD04%20CBT%20bluetooth%20device.JPG</a><br>
<br>
Enter the pairing code for the device. This one is 1234. Based on my
reading, other adapters may be different and some don't provide this
data in the documentation. Read the reviews on Amazon for the product
you're interested in to find out what other users did.<br>

<br>
Next, start up the Torque Pro program. Here is it's home screen. Once
you're talking to your car, this acceleration gauge changes to engine
RPM.<br>
<br>

<br>
Be sure to experiment with the menu button from different screens as
you will get different results. Tap the menu button from the main
screen to get to the preferences page.<br>
<br>

<br>
On this page, tap the CBT (or whatever) device that you paired with
before.<br>
<br>
Now, you can back out of the menus. After the system starts
communicating with your car, the other lights on the adapter should
start flashing and the gauge on the home screen should change to engine
RPM.<br>
<br>

<br>
This picture shows one of the multiple dashboard screens of Torque
Pro. Long tap an empty space to get a menu to add things. Long tap an
object to get a menu to move, delete, and change objects.<br>
<br>

<br>
Here are some other menu settings you'll probably want to set.<br>
<br>
On the ODB adapter settings page:<br>
<br>
Auto bluetooth on off - unchecked (I don't want it trying to find
the car if I'm in a building configuring it.)<br>
Faster communication - checked - if your adapter works that way<br>
<br>
By the way, I HATE the way that Android menu screens immediately save
settings and don't have a save and cancel button. If I accidentally
touch something, I have to scan the whole screen to see what was
changed and then touch it again and fix it. This also applies to some
of the menu screens in Linux.<br>
<br>
This program was born in some metric speaking country, UK maybe. Tweak
the following on the Units screen to get it to speak in US terms:<br>
<br>
Use miles - checked<br>
Use celcius - unchecked (all other use a metric thing lines
unchecked)<br>
Use feet - checked<br>
Use psi - checked<br>
Use gallons - checked<br>
US gallons - checked (rather than imperial gallons)<br>
Use cfm - checked<br>
12 hour clock - checked (or not if you prefer)<br>
<br>
If you have multiple cars, and you want to keep separate data for each,
go ahead and set up a separate vehicle profile for each. If you do it
later, you'll erase the gauges you've set up. This will force you to
have to set up a separate set of gauges on each car, but I think it's
worth it to have separate data. To do this, select menu from the main
screen, then vehicle profile, then add or edit as necessary.<br>
<br>
When you set up the profile, go down to the bottom and check the
advanced option to allow each car to have a separate dashboard. Save
the profile. Then exit all the way out of the app using the back
button to make sure everything is saved. Do the same when you've
finished configuring the gauges for each car. When you switch cars,
switch profiles.<br>
<br>
After you get the gauges set for one car and like them, save a screen
shot. On a gauge screen, tap menu, more, save screenshot, then share
by your email client, for example. If you're on a wifi only device,
you'll have to be within range of the wifi to transmit the email
message. Use a printout of this screenshot to configure your other
cars.<br>
<br>
Here's how I set up my gauges and the tweaks I had to make to them.<br>
<br>
Gauge page 1 -
<a href="http://dl.dropbox.com/u/9879631/ODB12%20Rons%20new%20gauges.jpg" target="_blank">http://dl.dropbox.com/u/9879631/ODB12%20Rons%20new%20gauges.jpg</a><br>
<br>
Going left to right top to bottom:<br>
<br>
01) Engine RPM - dial meter type gauge - change max range to 6<br>
02) Distance to empty - dial meter - change max range to 500. You must
set the gas tank size and current level for this to work if your ECU
doesn't report fuel level, as mine does not. Update the fuel level
when you fill up. I chose to under report my fuel tank size by 2 gal
to allow for a reserve. This is an estimate only.<br>
03) Coolant temperture - dial meter - change range 100 to 250<br>
04) Fuel flow - dial meter - change max range to 5<br>
05) GPS speed - digital gauge<br>
06) GPS speed difference - digital - Shows variance between GPS and OBD
speed.<br>
07) Fuel remaining estimate - bar graph - This is a calculated, not
measured, value.<br>
08) GPS Sat - digital - Shows the number of GPS satellites in use.<br>
09) GPS Acc - digital - Shows the accuracy of the GPS fix.<br>
10) GPS Bearing - compass - Shows the direction I'm traveling in.<br>
11) GPS Altitude - digital - Shows approximate altitude above sea
level. This is not as accurate as position.<br>
12) Speed - dial meter - set max range to 100 - This is how fast the
car thinks it's going.<br>
13) Volts Ad - dial meter - set range 8 - 16 - This shows voltage at
the OBD II adapter as far as I can tell. In my case, it reads about 1
V lower than a meter I have plugged into the cigarette lighter.<br>
14) MPG avg - dial meter - set max range 45. - Long term average MPG.<br>
15) MPG - dial meter - set max range 45 - Instantaneous MPG.<br>
<br>
Gauge page 2 -
<a href="http://dl.dropbox.com/u/9879631/ODB13%20Rons%20new%20gauges%20pg2.jpg" target="_blank">http://dl.dropbox.com/u/9879631/ODB13%20Rons%20new%20gauges%20pg2.jpg</a><br>
<br>
Going left to right, top to bottom. Many of the gauges here show the
same data as page 1, but sometimes with different types of gauges.
I'll mention the main differences. Digital gauges don't generally need
any range adjustments.<br>
<br>
01 - 05) Trip information gauges<br>
06) Engine on indicator - This is a special type of gauge, but can be
assigned to any sensor. I assigned this to engine RPM, then changed
the title from revs on to engine on.<br>
08) Trip reset BUTTON - Press this to reset the trip data. It ALSO
resets the long term MPG (not just trip MPG) data. I don't think it
should. But it does.<br>
<br>
I found out that unplugging the bluetooth adapter or exiting the
program also clears the trip data. I don't think it should do that
either, but it does. So, as it's currently programed, if you want to
clear your trip data, but not your long term MPG, just exit and restart
Torque. Changing the fuel level in your profile will also clear the
trip data. To leave the trip data intact at a fuel stop, leave Torque
running, leave the adapter powered (which may work without your key
in), and don't update your fuel level data in the profile. At this
point, your distance to empty gauge will be wrong.<br>
<br>
All the other gauges are variations of the ones on page 1.<br>
<br>
Using this program is really a blast. It gives me lots of great
information about my car's operation that I couldn't get otherwise.
And, having the 10" tablet screen to show them is really cool. This
runs the dual 1 GHz cpu's on my tablet to about 50 %, so I don't know
how well it would work on a slower device. I may think about getting a
4" or 5" tablet to permanently display a smaller set of gauges. If
anyone else tries this, please share how it turns out. I'll be glad to
answer anybody's questions.<br>
<br>
PS - I was hoping to be able to access the tire pressure sensors on my
wife's Hyundai, but couldn't. I guess I'll have to do that the old
fashioned way. Here's a retrofit tire pressure monitoring kit I'm
considering for my Toyota. It looks really cool.<br>

I have used the Torque product and ODB bluetooth on my Sprinter B3500

However, normally I have a ScanguageII sitting on the ODB port reading
off turbo pressure, voltage, MPG, and coolant Temp. <br>
<br>
On those occasions where it has thrown a check engine light and
corresponding code, the ODB reported code has been of marginal use.
It's Mercedes best translation. In those instances it had to go to a
Chrysler dealer who had the Mercedes computer to obtain the real
Mercedes codes. Torque didn't do any better than the
ScanguageII. Both Torque and Scanguage let you reset the Check
engine to see if it comes back. <br>
<br>
Frankly, I think handling an Android device in a moving car is too much
distraction for the driver. <br>

I have ordered an ELM 327 obd ii bluetooth adapter from amazon and am
looking forward to using it and the Torque program on my android tablet
to gather diagnostic data and provide virtual instruments on my car. I
was wondering if anyone else has experimented with this, and what kind
of things you're doing.<br>
<br>
Also, while I'm sure I'll enjoy using my 10" tablet for this purpose,
I'm also sure I don't want to mount that in my windshield permanently.
So, I'm wondering if there is a cheap 5" android tablet or a cheap 4" -
5" smartphone I could get on ebay or elsewhere, for example, that I can
use to run android programs without a cell phone account. I would want
it to run Android 3 or 4, preferably 4. I might consider permanently
mounting something like that in the car.<br>
<br>
Any info you can share on the topic would be appreciated.<br>
