OBD 2007 works with any Elm327 chipped scan tool or any scan tool powered by a chip that fully emulates all the AT commands of the ELM 327 chip. There are many manufacturers of Elm327 chipped scan tools, so theoretically we support any scan tool powered by an Elm327 chip.

However, we directly support the scan tools you see on our main page, because these companies have proved to both reliable and supportive. We are confident in recommending any of these scan tools because we have observed the quality of the products and can vouch that these scan tools are all made to the highest standards. We have also extensively tested each of these products with OBD 2007.

We have created a table of features comparing each of the scan tools we directly support. If you are new to OBDII scan tools or even an experienced user considering an additional scan tool, we hope the following table will highlight the various features of each scan tool to assist in your decision making.

High Speed Baud Rates and Double Buffering
The first two features are primarily aimed at the high speed CAN protocol, the protocol used by all new vehicles manufactured since 2008. When the CAN protocol was first introduced in vehicles during 2004/05, many Elm327 chipped scan tools suffered from BUFFER FULL messages, as a result of the high speed CAN networks of the vehicle over running the small internal buffer of the Elm327 chip. The OBDPro scan tool, overcame this limitation with its unique double buffer design, so that BUFFER FULL messages were eliminated even at low speed baud rates.

However, why use slow baud rates (9600 and 38,400 baud), when a USB port is capable of speeds of up to 2.0Mbits. The OBDPro scan tool in conjunction with OBD 2007 can exploit the very high speed baud rates of the OBDPro scan tool up to 4 times faster than the current Elm327 v1.3 chip. If you are seeking high speed performance, then the combination of OBDPro and OBD 2007 is the obvious choice.

Remote Upgrade Capability
This feature of OBDPro is truly unique. OBDPro is the only ELM 327 type scan tool, which is remotely upgradable. Your scan tool investment is protected, because when any new firmware release is introduced, you have the ability to upgrade your scan tool, by running a free upgrade program from OBDPros, while your OBDPro scan tool is connected to your computer. Within a couple of seconds, your firmware is upgraded to the latest version, so your scan tool is always current.

To do the same thing with any other ELM 327 chipped scan tool requires purchasing a new chip (~$US32), waiting days or weeks for delivery, dismantling/assembling your scan tool, removing the old chip and replacing with the new chip. Removing and replacing the 28 pin Elm327 chip is not for the faint hearted. Just don’t break or bend one of those 28 pins.

OBDPros is the complete one stop shop – they design their own chip, plus build their scan tools.
