WOT with NB O2

[vacuum 6]

With running 93/E85 (30% mix), do you still target .78-.80 3rd gear WOT?

assuming the the o2 sensor is a standard one calibrated for gasoline...
yes

ps,

id think about going to a wideband if your going to step it up anymore
that narrowbnd tuning is just a little too shoot from the hip for me...

ive talked to eric marshall about this and he says that the 02 millivolts arent accurate with e85. I basicly lean the car out till it knocks then go up 3% in duty cycle. Hope this helps.
