Should I tune for the same O2 readings with alky?

When using C116 and no alky, I tune for O2's in the 770-780mv range. Now, once I get my alky kit, I know I need to cut fuel back, but do I still tune for similar O2 readings?
 
Those O2's sound correct for alcohol also, as long as you don't have knock.
EGT temps seem to be a more consistent tuning tool than O2's though.
 
Yeah, I don't have an EGT yet, but plan to get one. Thanks. I just was not sure if the alky would have any effect on O2 readings since it measures oxygen I was hoping it would be the same.
 
Actually most that run C16 tune lower 700's. Alky you tune 770-780's. EGT's in the lower 1500's.

Should be able and run the same if not higher boost on alky pumping in sufficient volume.

With C116, I start getting knock if the O2s go much below 760mv at 25# and 24 degrees.
Ok, so I tune for roughly the same O2 readings as I have been.

Lets say with C116 and no alky, and a certain boost level, my O2s are 770mv.
If I simply add straight methanol, will the O2s jump up significantly?
Just trying to get an idea of how it's going to behave when I get your kit Julio that I order from you last week and start tuning.

Yes.
