Anyone have the Apexi pen style turbo timer?

I lost my instructions but i'm trying to figure out how to set the a/f gauge accurately. What is the correct o2 voltage supposed to be around on our cars?

you wouldnt have found that in the instructions anyways.
@ cruise cycle up/down from .3 - .8 or so
@ WOT .92 = the mark

Well mine must not be tuned right b/c at WOT i get 1.06 at times which is more than pig rich. What is the voltage supposed to be?

.92 is what its suposed to be.

Ok i'm a bit confused on how my turbo timer works. But it has two readings a/f and o2 sensor voltage. The o2 sensor voltage is usualy what i look at but the a/f gives readings such as 14.0>. So what is the a/f supposed to be at.

i think ( going from memory ) the a/f should be at 14.4'ish
o2/af are the same things, 2 diff ways of looking at it.
