Flex Fuel on LS1 Y-Body? Anyone out there done a flex fuel conversion on an LS1 Y-Body? I did a search but came up dry. Very interested in getting something set up to do so.

Just about any aftermarket ECU can do it. If you get a flex fuel stock ECU, you can do it that way as well. Either way, you should install a flex fuel sensor on your return line to measure ethanol content.
