Whats Wrong? O2 readiness not completeing... What might I have incorrectly configured in my tune that would keep the oxygen sensor readiness test (not the heater test) from completeing?

Well if you dont have a check engine light i wouldnt worry about it to be honest.It might take you a couple of months to set the monitor and it was an o2 sensor on a vortec 454 truck that i had put a motor in i had to drive it around for 3 months before it set, all the monitors are for when you take it to a smog shop to see if you just tried to clear a code to make it pass smog all the monitors will be reset and there are 2 parts the o2 readiness and 02 heater readiness.O2 sensors on an obd2 system make very little fuel decisions mostly are there to save the converter.Atleast this is what i was taught in a class i took on obd1 and ob2 drivability and performance.

before anyone reads this my bad, after posting i just noticed how OLD this thread is lol, thats what i get for searching :/
how did that work out for you at the shop for inspection, any issues? are you With kaltech? Brian and Steve did the tune on my 99TA two summers ago back when they were in deer park. I too am from the LI Area (Smithtown)
I keep getting a recurring knock sensor code that set the mil light, went away ( the SES light is now off) but its still in the freeze frame and occasionally i get a pending code which then goes away. on top of that after numerous drive cycles i cant get my o2 heater test to complete and i've cold started the car several times. And with all of this there are no other codes or SES light.

No relation to kaltech, other than brian being a buddy of mine for years now. Hes a good guy and does some solid work to an ECU. Lots of good numbers coming out of his shop last i checked.
yeah before my ls6 intake with Full Exhaust (LT, ORY, Magnaflow and Elect Cutout), lid, and tune he had me movin about 325 to the wheels. With my 4400 2.6str Stall and MT ET's i Ended up running a 12.4 with a 1.7 60' at Etown and being my first time my Reaction times were HORRIBLE haha

lol j/k I'm only in setauket now so not too far, stop down and I'll plug in and check any codes that are pending or in history. unfortunately the startup company didnt pan out as hoped 
i go to Stony Brook so your 5 mins away lol, ill try and stop in around 11 tomorrow after class. Right now I have a Freeze frame and pending p0332 knock sensor low voltage. other than the no matter how many cold starts i do the stupid o2 heater test wont complete.

How you "delete" the codes can affect readiness tests.
If you do it by disabling the code, and that test was
a dependency for the readiness "rollup", then it may
fail to complete. However if you make it "enabled, no
error reported" then it can support the subsequent
readiness checks.
