P1000 Pv3, Machine running lean

[z28camaro82]

Guys wondering if anybody has setup to read stock o2 sensor. When the machine starts its rich so running 1.1 range rev it up a few times and it drops on down to .8 which i think is right. Rev it then and it goes down to .3. Im wondering how erratic that normally is?

Plus if its lean what do i need to check and why isnt 02 sensor richen it up?

Any help be appreciated. I wish i would of looked at these numbers when i first put tunes in.

Flash it back to stock and data log it so you have a baseline to work with.

im pretty sure the stock O2 sensor is a narrow band sensor, so it pretty much falls off a cliff on either side of stoichiometric
to really see whats happening you probably need a wide band sensor.

i tried to look at mine and couldnt make sense of it either. it just jumps around too much.
