flex fuel tunning?

I have a post in the FI section. Basically there was a link there saying you can convert certain ECM's to flex fuel. Just wondering if I have the right one. Mine is a 0411.

Thanks!

You need to load a flex file (L59 operating system file) in the 411 PCM. It will work. Insure if all L59 files are DBW as my 2002 suburban is.

What if my lq4 is DBC? Will the dbw files work with that?

Dunno but you need to change the obd2 codes and installed options matrix to reflect the dbc config hardware. Too busy to test now.
