Considering doing a flex fuel setup on a 2007 CTS-V. Just wanted to see if anyone else has done this successfully on this year/model. Most of the research I've done made it sound as if the functionality is there, and it really is just a matter of adding the sensor, the supporting fuel system, and turning on the flex fuel option in the ECU. Then tune accordingly. Anyone have any real world insight?
Thank you!
That's pretty much it. Very easy tuning wise.

Yep, really easy. Just make sure your tune is dialed on gasoline and you're good to go.
I appreciate the responses. What you are saying is what I was finding in research, so this makes me feel more comfortable.
Only small thing is if you've been tuning on say E10 pump fuel when you add the sensor it'll pick up the ethanol content and change the stoich AFR value 4-5%, so you may have to make a correction to the whole VE or MAF tables to adjust for that percentage. Should just be a 4-5% change across the board.
