IIRC with the little information around this forum about the procede flash, you are supposed to disable O2 biasing completely and allow the flashed DME to do the fueling. That being said, you'd need an "Ethanol flash" for the car to hit the correct targets, I dont know if vishnu uses a one-off flash or has one for gas and one for Ethanol.

That being said, not sure if the flex sensor adjusts fueling depening on alcohol content, but it should auto adjust the agressiveness on the fly.
