Tuning: Wide Band O2 Sensors - and Water/Methonol Injection

[car_habbit]

Is there a table or formula to correct the indicated Air Fuel ratio from a wide band oxygen sensor as a function amount (% of fuel) Methonol mix injected and the Water/Methonol mix percentages?

This is a CRITICAL issue for both dyno tuning with WBO2 and for Wide Band closed loop fuel injection systems:

If I have a car that will not run at full throttle without detonation, I need to do even the initial tuning with the water injection on. Wide band O2 sensor readings will obviously change with the water/methonol injection, so it is necessary to correct the indicated reading. In this case, the user does not have the typically suggested luxury of running without WI to set the fuel before adding WI.

Is there a table or formula that can be used to correct the indicated readings to get reasonably accurate corrected readings?
