What do you find so amazing about it? Will it work on an iPhone? I'm locked out of YouTube here at work, but some of our other members might be interested in how you have used it and what benefits this specific product may have.

Thanks for sharing your experience.

Well..for 12 bucks you get the functions of a $300 dollar scanner and you can display live current sensor data from the engine such as Calculated Load Value * Coolant Temperature * Fuel System Status *Short Term Fuel Trim * Long Term Fuel Trim * Intake Manifold Pressure * Timing Advance * Intake Air Temperature * Air Flow Rate * Absolute Throttle Position * Oxygen sensor voltages/associated short term fuel trims * Fuel System status * Fuel Pressure and a whole lot more.


Not sure about iphone

So you're basically talking about a wireless $12 function for diagnostics? For the people who do not normally work on their own cars? Sorry, I am the newbie, just trying to figure out what you're recommending. Normally when I see the word bluetooth I think of telecommunications or audio equipment.

Actually my Garmin nüvi has a Bluetooth adapter that provides all this information. When you're driving the car you learn what the proper characteristics are. It allows you to see if there's any problems long before the problems ever show up.

Multiplex?

Is this OBD2 a single channel device, or does it support multiplex functions?
So on post 2001 machines, you can access lots of different controllers?

Iphone will only use Wi-Fi and not Bluetooth unit. The Wi-Fi unit to do this cost around $100. If have the Bluetooth and use it with an android tablet. Paid $5 for the upgrade app. You can reset the CEL after you get the codes.

Bluetooth is a low power signal that permits two items to connect to each other. Has a range around 25 feet.

I am not certain, if you mean that can it handle monitoring multiple setting thean yes it can. It has a huge list that can be monitored.

Sorry, might not have been clear.
There are lots of controllers in the system (that's part of the problem people have diagnosing problems) and so you need to interrogate each of them to find the fault codes.
However, the big hitter is the engine ECU, and I understand that is the default connection. (Each controller may have many parameters that it can transmit, so even the engine ECU can be impressive)
But, being a CAN bus car, you may be able to get to other controllers.

For example, when I had my car checked at the local indy, I got the report from the CCM (Multifunction control module) that it could not talk to the A37 PSE (which is not a surprise, since it's missing, but is a diagnostic function I had not expected to be able to find)

For the 38pin connector, the diffferent controllers use different pins; I'm not sure how this is done for the 16pin OBD2 connector, unless the bus is multiplexed.
Hence the question.

Alright, so I was thinking of putting up a new post but now that I see theres already a post about a bluetooth OBDII scanner and torque software, I'll just add my information here.

As a quick view of what this kit can do ($11 for cheap OBDii scanner on amazon + $5 for torque app on the app store) see attached image, it can record all you sensor information and automatically upload it as soon as you turn the car off. then go online and see all the information graphically.

you can also do a routine scan and polling of all sensors (in a matter of 1 minute from start to finish, all while driving with the roof down on your favorite highway ;)) and figure out if somethign is wrong of getting wrong. for example see attached report snapshot 'sensor test report.png' which was emailed to me by the app. Also attached is a screenshot of what the app showed me. For all those I now know that my 'fuel system monitor bank 3' has failed and something else(?) has failed. Will start fixing it and hopefully it will save me a LOT of money (visits to the MB dealerships are fcukin expensive)

Think that's already a lot for just $16 bucks? but wait...there's more, you do your good old OBD error scan.

Only think to keep in mind is that DONT LEAVE THE DEVICE PLUGGED IN OVERNIGHT. I left my OBD2 scanner in the car port for 3 days, the 4th day mornign my car battery was fully drained.

I was interested in this thread, but it seems to have just ended (unless I am missing something).

I am a Mac -based person, and interested in a device (plug in or bluetooth) that can read all the usable and meaningful data available such as the MB dealer might. Not certain of terms and the technology but does a good scanner read the OBD2 diagnostics and the CAN-bus based diagnostic information? I realize that all cars sold in the US since 1996 are mandated to have the OBD2 interface, but is the key in being able to get all the available diagnostic information the software itself? In other words, does a OBD2 plug-in scanner, if given the right software to run, and interface with all the car's computer systems ("controllers", I take it?) including Can bus stuff?

What a newbie I am..

The common readers won't give you nearly what the dealership's SDS/STAR computers will give you. Knock-offs start about $1000 USD.

Checked out both cars, way more than I under stand.
Porsche Cayenne S 2004 with 75,000 mile check out fine on bad codes. Took it out on the road but could not get in am area to test out the 1/4 speed and time LOL.

2002 Mercedes SLK230 with 114,000 mile
had 2 bad codes one red P0135 O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1) not sure how bad this is or what. tried clearing it but came back.

The other was gray code
P2032 ( I thought it was code P2022 but there is not a code with that number) Exhaust Gas Temperature Sensor Circuit Low (Bank 1 Sensor 2) again not sure what this is or if it is serious.

This is what read out

[FONT=&quot]TID:$06 CID:$02
- Lean to Rich sensor switch time(calculated)
Max: 25,000
Test result value: 65,535
FAIL


Should I be worried. :confused:

Thanks guys. This is the info from Amazon on this thing:

Currently unavailable.
We don't know when or if this item will be back in stock.

Since you all bought one, there aren't any more left. Geeze.

Take a look at the Torque Software site. There's a list of tested units on there, which may help you choose an alternative, if you're impatient to get started.
