So, if I got a flexfuel sensor installed, I could see this ETHANO field presumably.

I don't currently plan to modify my tune beyond the Magnuson-provided tune. I enjoy the car immensely as is, and I could not use any additional power anyway without changing the rear wheels from the OEM LT1 8.5 inch width, and in Canada a new pair of wider (still only 9.5") rear wheels that match my current wheels would cost $1800 Canadian plus sales tax, which is ridiculous. I just want to be able to see what the local ethanol content is in the 91 octane fuel we have available here (no 93 octane and no e-50 or e-85), and how much that ethanol percentage VARIES, since that will cause variation in performance.

However, 3 questions arise:

1. What is the parts and labour cost, plus tuning change cost (if required) for a flexfuel sensor?

2. What ECU software tune change(s), if any, are required to merely ensure that this ethanol percentage field in the OBD2 output is populated? (I already know that Banks requires the addition of their physical "data bus" add-on to see outputs from any sensors added beyond OEM sensors)

3. Davenport Motorsports told me that Magnuson's warranty is valid only if the Magnuson-provided tune is unaltered. Would the software changes to the ECU be potentially viewed as an alteration that therefor voids the warranty? (I suspect it would be viewed as an alteration)

I am beginning to see the potentially bottomless cost pit encountered if I mod the car beyond its current just-fine state . . .

1. You would need a flex fuel kit installed, whichever your tuner prefers. Should be 1 or 2 hours for labor.

2. Someone else can answer, I do not know.

3. Your blower warranty will be voided if you use another tune. I wouldn't worry about blower warranty, you won't hurt the blower with how slow it is spinning, and from what I understand, the warranty on the blower is BS.

Yes, this is why people either just do bolt ons, or just bolt on a blower and let it be. It gets really expensive really quickly to go further.
