Set the engine to a 2000 RPM fast idle in closed loop at 14.7 afr, engine hot.
Start recording a datalog
Let it idle unmolested for 30 sec
Spray water mist into the intake for 30 sec

Megalogviewer will record exact RPM, AFR (xx.xx), injector pulse width (x.xxx milliseconds) and wide band sensor correction (x.x% correction). If the water has any positive or negative effect, it will show as a change in RPM, pulse width or ego correction or most likely all 3.
I trust you're going to use pure water for this, and not a 50% mix of ethanol and water?
