O2 sensor readings

Will running alcohol (40%) affect the narrow band O2 readings we use to tune WOT? This is on a GTP.

It will read slightly richer but not as much as it would with using race gas.

OK. So if the O2s before alcohol are, say .940s and alcohol is added and the commanded AFR in PE mode is tweaked to get readings of about .940 again, the mix will just be slightly richer than the pre-alcohol tune that produced .940s, right?

Different sensors read differnet on vehicles. But as far as it goes on a GTP I would only see a diffence of system off 910 02's and 930 02's with a 50/50 mix.

Thanks. I appreciate it.
