Going into close loop early

[John377]

Can someone point me in the right direction as to why my vehicle would continue to go into close loop after about 10 seconds after a cold start? All of my close loop enable tables are set to higher temperatures lowest being 131ﾟ. But it still goes into closed loop even at 86ﾟ.

Or if its not closed loop why are the STFT's adjusting fuel before warm up?

Is there another table that also affects when closed loop or STFT's are enabled that may affect this?

This is a 2002 Silverado 6 liter gas with an SD tune.

Try Fuel/Open Loop-Base/Open Loop, there is an enable/disable for STFT Open Loop operation.

Wouldnt this just disable STFT entirely? Or is this just for open loop?

So I did turn this off and it worked perfect thank you. I was just confused as I got some help from an labeled "advanced tuner" on this site and he told me to leave it on.
