Consumption wise, I think i'm seeing about 20% more than pump gas but the fuel cost itself here is around 25-30c/L cheaper than high octane pump gas ($1.30/L compared to $1.60/L), the car doesn't stink at all anymore, runs cooler and way more throttle response.

Ethanol is only evil if you refuse to play by its rules.
Does the flex fuel sensor need any time to adjust or is it instantaneous? I’m right in the middle of going efi with this same GM sensor
