Just like any other vette. You add a sensor, adjust the tune. It allows more timing/aggressive tune on the higher octane gas. Yes it would have warranty issues. For a stock n/a person, maybe a few ponies. For a big motor build, big cam, etc that bump compression then you can take advantage of the higher octane.

you can enable flex fuel in the tune and choose sensor present and you most likely will have to also make sure the sensor calibration is correct in the Engine Diag tab but I haven't looked.

We have been testing our system for a bit now. And all I know is the car is a whole different animal we got to walk gtrs on e85. Where would it place me on the fast list if I used an e85 to reset the bone stock record?

Just because the ECMs have E85 tables doesn't mean they work. Not all cars have an ethanol sensor. Remember, GM shares a lot of parts, and that includes ECMs, which are also in the trucks.
The E92 has whole entire sections for superchargers and turbochargers. That doesn't mean there is one under the hood.
Hardware....software....not the same thing.
