Finally, you may be able to buy new old stock (at a discounted price) from a GM dealer of the discontinued sensor. That will likely be a more expensive route, but still better than the $500+ they apparently want for the current model.
Good luck,

I really need to get the flex fuel sensor, this is some good stuff. I added 2 degrees of timng globally, and another 2 in the regions I was knock limited. It makes ALOT more power. In 4th gear, it is enough additional that either:
1) The clutch is slipping
2) The engine is accelerating so fast it sounds like the clutch is slipping
Keep in mind this is a boosted car @ 21 psi, and I was able to add 4 degrees of timing at the torque peak (maybe more, that was my first guess).
I just drove to the station and filled up on my lunch break (and loaded a tune while it was pumping). So I haven't got much driving time yet. It feels great though, and the smell is also nice
