I have a 1991 Chevy V3500 with a 5.7/4L80E,and I need a .BIN file for my 7060 ECM with a broadcast code of AWBP. I have the .ADX file I got from Tuner Pro R/T, and I also have some other .BIN files that are supposed to be for a 1991 GM with 5.7/4L80E, but the broadcast letters do not match up with mine. Is the broadcast letters matching up even matter? I tried the BCC .BIN file search engine on this site, but it only returned a"read error" in the search.
