Put about 50 miles on it today and about an hour of tinkering with the gadgetry but it works sucessfully for the most part.
Here's how I did it:
Bluetooth device:
ELM 327 Version 1.4
Got it from ebay seller
tomtop.wholesalerNot much to say about it other than it functions as it should. It's mearly a bluetooth interface between the hand held device (smart phone) and the cars ECU. Can say this about the seller, I ordered it tuesday, got shipping notice Wednesday, Thanksgiving was Thursday, and it arrived in my hand shortly after noon on Friday. That's fast!
Cost=25 shipped
Torque android app:
Lots of info of what it can do online and it's ever expanding. The owner has released protocols for others to build plugins to expand its capabilities in the future. More info can be found here:
Torque--OBD2 Performance and Diagnostics for your Vehicle.Cost=5 dowload
Assembly:
Now that you've got both of the things you need lets get it working.
ELM 327-plug it in your OBD service port. That's it, nothing else to do here. ECU power is supplied to the port and that is what powers the module. No batteries, wires, or other hookups. Its gotta be simple enough for your big auto chain store high school dropout to be able to use it. (I know, I was a manager at Advanced Auto parts for five years)
On your device:
You must pair the ELM up with your device. The following is done before opening up Torque. Go to settings, wireless connections, bluetooth connections, and scan for device. Mine showed up as CHX with a bunch of numbers in brackets. Click on it and when it asks for a pairing code, it should be 6789. According to the manufacturers website this is universal for all their similiar products. It will do the rest by it's self and you can go back to the home screen.
Turn on GPS satellite receiver:
You can do this several ways. It is buried in settings somewhere, but I have a handy little shortcut on my first left page. It eats up battery to have it on, so when not in use i'd suggest turning it off if it isn't needed for another app. For this very reason I plan to hardwire in a charging cable and run it up to my windshield mount for long range driving.
Open up Torque:
Set up your vehicles profile-click the menu button and you get settings, vehicle profile, and quit. Click profile first, (we'll come back to settings later.) new-profile, You'll now be shown all kinds of info that needs to be input. We'll start from the top.
Profile name-I chose Liberty CRD for mine
Eingine Displacement-2.8 it's in liters
weight in kilograms-1920kg for this porker
Fuel Type-diesel, duh
boost adjustment- 0 will be fine unless you get way high in the mountains where air pressure at sealevel isn't the normal 14.7psi
Max dial RPM-5000
VE%-85% I haven't seen anything that says our engine is a different number
Fuel cost-3.69 average cost around here
accumulated distance travelled-Odometer-65000 make it exactly what yours shows. The program will keep up with it from here.
MPG trim-1 don't mess with this unless your mpg calcs are different that what torque shows.
Advanced, use seperate dashboard layout- Not sure what this does yet, I left it unchecked.
Advanced-connect using this bluetooth connector for this profile. Check the same one you set up on you phones settings earlier.
Use alternate obd header, I didn't have to use this one left unchecked.
Preferred OBD2 Protocol-SAE J1850-VPW (10.4k baud)
(note: When left to auto search it will work but only the tach and TPS % will function. I tried all others with varying results. The best I could find was SAE j1850-VPW. All gauges worked except the TPS%. Gaining boost and coolant but loosing tps, I could deal with that. DO NOT USE USER1-CAN or USER2-CAN. They both disabled ABS, ESP, and all the other electronic gizmos that drive for you when things get crazy. My instrument panel light up like christmas when I tried to use those two.)
Click Save.
This is the first step to have this going. You do not have to have your car running to do all this, key on-engine off.
Use the setup:
Wait until all four little blue icons turn solid. left to right, GPS, Phone, ELM, and profile. Once the last one lights up your talking to the ecu. Start the car and hit realtime information and you should see some results. You can also pull up codes at this time. There are gauge settings and such you can change that are fairly well explained on Torque's forums, I'll leave those up to you to explore and change to your liking.
I wrote this as a guide to get you started. I've got just a few hours playing on it but it hasn't locked up or caused any unusual problems other than the traction control shutdown, but that was just me exploring functions. If you can find better setups, bug fixes, etc., please post them up on this thread.
Pulled codes and got:
Current fault U0121 - Network
Current Fault P0102 - Mass or Volume air flow circuit low input (ORM)
P0100 Powertrain Mass or Volume Air Flow Circuit
P0203 Injector Circuit - Cylinder 3 (uh oh, Fumes have been really strong at idle, stuck open?)
B2TAE-Body ??? net search revealed nothing.
