I finally got time to look over the GM ECM info at http://www.diy-efi.org/gmecm/ecm_info/ There's a .zip file (ALDLStuff.zip) linked from the ALDL data stream formats. It contains a text file - aldl.ds - which describes the serial format in pretty high detail, and a description of what the data streams for a whole lot of ECMs (including mine) actually mean. Good stuff. Real good stuff. Now if I can just figure out how to convert 8-bit binary into ascii digits, I'll be set. :) --Danny -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
