WOT AFR and O2 reading

[Weatheralls Auto]

Getting ready to finally do the WOT tune, what would most recommend as a Target AFR and O2 reading?

AFR Widabande 12.4 ?
HO2s 875 ish?

What have you set yours to?

(for engine in Sig)

for N/A, i like a target AFR of 12.5-12.9:1 with pure gasoline. ethanol presence requires a richer AFR for best results though.

i use Tunerpro to automatically calc the AFR from the O2 voltage, but this should work for manually converting the numbers. just follow the highest temp plot(since you have a heated O2 and it should be able to stay roughly at that range)
