This means theres a whole heap of available information,software and knowledge on the web as this standardized protocol is widely used,reversed and developed around the world. Looking specifically at the commodores, the OBD2 protocols that GM uses is VPW and CAN protocols. So technically, ALDL, VPW and CAN are all different protocols, that speak different languages and all have there specific functions.
One condition of downloading this software is that you must tell us how it worked with your hardware!Feel free to send me your definition files, and remember to check out Dan Burk's mostly160 baud ALDL data stream definitionspage with lots of US vehicles listed there.Updated Software?In October 2001 a Windows based ALDL porgram WinALDL by Jonas Bylundwas released.For those people with a limited laptop (less than a 486),we have already updated and added 8192 baud support to our next version of ourDOS based ALDLLOG program, and hope to be releasing it soon.Because of the greater information content in 8192 baud data streams,this version has multiple page displays and decodes individual data andstatus information into real-world scaled values such as temperature, speed, etc.rather than just raw binary/hex information.We are working on a user configurable definition file format that will allowyou to customise your display to your individual requirements.We may even provide a Windows version for the DOS challenged!
