Which ECM with Which Car...Diacom RevEng

[lkurek at smtpgate.anl.gov]

     Well, I'll tell you what....
     
     I have the Diacom Plus software and it is unquestionably one of the 
     best pieces of software I have ever bought. They do have a GM 
     calibration file which lists all of the GM cars from the first ECM 
     through 1995 models. I would think it has both calibration info, along 
     with what sensor inputs/outputs are available in the data stream for 
     each model. 
     
     I just uploaded a full copy of the diacom software, along with the GM 
     configuration files for it (FTP site...Incoming 
     Directory...Diacom.zip). Feel free to check out the calibration files 
     and if we can reverse engineer them, perhaps we can determine which 
     cars used which ECM. The software is useless to hook up to your car 
     without the "active" cable they supply with it, so please observe 
     copyrights as appropriate.
     
     If anyone needs to see a capture file, I have them from a multitude of 
     F-body cars (87, 94, 95) along with one froom an 89 Cavalier 4cyl.
     
     TTYL...and happy reverse engineering!

     BTW...the files were zipped from C:\Diacom\

     It seems that some GM controller is our best bet for the universal 
     controller due to availability of info (even if the EEC is a bit more 
     powerful?).
     
     Square 1 is still:
     Does anyone know of a list of which controllers are in which cars?
     
     
     Also...what competitors are there to Rinda Tech's Diacomm software for 
     monitoring the GM ECU?  Any feedback about Diacomm?
