Re: .ecu

["Bruce Plecan" <nacelp@bright.net>]

GM uses numerous different .bin files (code) for any given ecm..   For the
730s if you look at location 0008 that is the mask ID number.  The mask is a
templete that when all the tables are laid out they line up with this..
Hence like in the 749 is one example where the 4 + 6 cylinder variants
(Syclone+Sunbird) use the same mask, but for very different applications
(Yet still both turbos).  On some apps., just going from F body to Y Body
gets a new mask.
