I'm looking for a raw aldl data log so I can try to figure out how to read from the car computer. I'm in the process of writing some software for a project of mine, but all I can find for the ecm info is how to build the aldl cable, where to find data loggers, and all sorts of things about burning/editing the prom data. What I want is the actual data the ecm sends to you when you do data logging. Any resources, info, etc. would be great.

Edit: I think I may have found some info on what I was wanting, but due to the lack of access to a laptop right now, I can't test it. http://www.diy-efi.org/gmecm/ecm_info/ has some aldl stream info along with some other data on the ecms. If anyone has messed with reading the streams via serial port, are the stream specifications they give correct and do they match what you have found in reading the data?

 

No one?
