I am going with a 12200411 ecu and need the 2002 Chevy express van 5.7 automatic .bin to start using tuner pro. I thought finding the bin would Be a piece of cake. I guess I was wrong or I am searching for the wrong file type. Any help would be appreciated.

With OBD-II vehicles you need a means to read the bin from the PCM (in this case a 12200411), and then write it back in again, after making changes.

With the correct XDF file you could use TunerPro to edit the bin file.

What read / write program were you planning on using ?
