Alcohol and o2 readings

[BOP4ever]

Seems like I read that spraying alcohol screws with the o2 reading . Is the true?
Do I need to tune fuel at lower boost and no alcohol?
I have had issues with low o2 730-760 mv even adding 10-15% fuel.
Pressure rises with boost, so I think the pump is ok and is hot wired etc...

If you don't have a wideband O2 installed, just go by the scanmaster and tune for no KR at WOT.

Not the single wire O2 readings.

Low level fuel tuning usually isn't needed with modern chips unless there's a driveability issue and a wideband is even more helpful in diagnosing those.

Just my .02.

pressure should be checked at wot,pump could be dropping off.if your not seeing an increase number on the sm its not because of the alcohol
