Setting up the ELM327 OBD-II USB interface with ScanTool.Net Software

In this video, I got my hands on a sweet little piece if discount electronics designed to interface with a vehicle's built-in OBD-II computer interface. I did this using Windows 7 and the built in Serial-to-USB drivers (downloaded and installed by Windows 7 automatically). ScanTool.Net is GNU licensed, Open Source software that is free to the public. It is designed to read diagnostic information (trouble code and sensor data) from generic OBD-II hardware interfaces.

@0778drz110 - the color bit thing is the result of a poor interaction between the ScanTool app and the video subsystem. I'm guessing that the ScanTool app is based on the MS .NET libraries. (Based on name AND symptoms.) I've seen poorly coded .NET apps completely freak out... Not showing up, not updating (like this program), or just flat out crashing and refusing to run. The best advice I can give you is to update your video drivers from the vendor web site (and NOT Win update). Good luck man.

No, this strictly the USB model. No Bluetooth or wireless of any kind. I've never seen the Bluetooth variant of this device, but it *should* create a COM port just like the wired version. The trick is to configure that Bluetooth to COM1 INSIDE OF DEVICE MANAGER. If you configure your COM in the scantool software, but not Device Manager, it wont work. The COM numbers must be the same. And this particular program I used seem to only prefer COM1. Use device manager to config your port to COM1.

No, it was a 64bit OS.

@TheKillaInc, shoot me an e-mail with your COM port configurations and any error messages and I'll try to help you out.

The system in the video was also Windows 7 64-bit as well. Is your device showing up in Device Manager?

I love how you are using this and don't know what anything means LOL

Great video, I had the same exact problems with this software and you totally sorted me out. Cheers, very much appriciated.

The program that you are using works very well with XP. So you don't have to adjust anything. :)

I have this program but I do not want to work with several cars. honda 2001, peugeot 1.4 2004, astra III 2006 - ELM 327 1.4a

@pspdennypsp i think it is broken..... can't trust products from China.... i don't use it anyway

[pspdennypsp]

@ExtraTerrestrials Hi, I have the same thing ...

Have you sorted it out already ? :)

If you want to fully utilize these you must find out what these terms mean and its not that complicated to understand basic feedback function from sensors and how CPU adjusts based on.

@kuningmuda i am trying to do that now , did you get yours? i bought a cheap usb adapter from ebay for 1.50 and i am trying to pair it up with my elm327 bluetooth. i am having lots a problems with the com settings .

[estrelladelnorte1308]

@stevoinco i bought one couple months ago, is really nice and it works with this cool app on my android called "torque"

-evap system is the system that controls fuel vapors and such so your car doesn't blow up LOL

-cat temperature, temps of the catalytic converters on the exhaust. they need to be really hot to burn off harmful emissions but too hot can mean that it is clogged and needs to be replaced.

-short term fuel trim, the computer adjusts fuel settings for driving conditions in the short term. Like if you are late for work one day and you are hard on the gas

-long term fuel trim, same as short term but over a longer period of time. Take for example a teenage boy's car vs. a old lady's car. The boy's car has much higher fuel settings over time

-bank 1 and bank 2 designates which side of the car that sensor is on(search google to find out which side is which)
