The ambient air temp sensor is not a precision measurement. The output is not linear either so converting it to temperature is tricky. It will read a few degrees low when it's cold outside (below 40 deg F). The sensor is located just downstream of the air filter. Yours reads the same as everyones.
You should not use the stock O2 sensors to determine A/F ratio. If the Zeitronix has a linear 0-5v output you can run that the Interceptor and read A/F there as well as log it. This is what I do with a AEM unit.

I have Zeitronix wideband as well as Aeroforce & the O2 reading I'm seeing is 924v at 10.4 at WOT. Seems different than what some of you guys have seen. It jumps around a lot so it's not a good tool compared to real wideband.
On TPS at idle I'm at 17% & WOT is 79/80.
On stock turbo, Cruising on the freeway at 80 I'm right at 1500 degrees. At wot it is going to 1650. I don't have my EGT probe setup for the stock manifold, only my S3 so no comparison yet.
Is ambient air out side temp? Or the difference between out side & intake temps? My ambient temps are lower than my intake temps. Not sure what they are supposed to be, but ambient is lower than outside air temp. maybe mine is off somehow.
Not seeing any knock value, but I am seeing 0-2 knock voltage. At what voltage does it become a knock reading?
Ignition advance has been from the teems to 60 at times. I have not tried advance at WOT. maybe at lunch.
Boost has been between -18 to 20Psi. Exact match to my Zeitronix digital guage. Glad to see that.
less info...i prefer my upgraded pro version
