Does that make any sense? It was cool and dry out on the later runs, but the computer should adjust for that, right? I'm a bit confused. I was shooting for 920ish since I run the car hard at the roadcourse for 30 minutes at a time.

 

TTT.....and also, is that a lot of fuel, or not really much added?

 

I don't know why it went leaner, but it's not a ton of fuel. I'm sure you know the mv readings aren't that accurate as 885 was like 12:1afr on my last pull. .25pts on my PE table was worth about 1pt of AFR.

 

I just want to make sure the decimal was right (.25pts ~ 1.0 pts of AFR)?

So if I only added .040, than it might be only about .16 pts of AFR. That's good to know how slight of changes I'm making.

 

Do you have COT enabled? After doing a few WOT runs, COT protectection started making things very rich for me.

 

At that point (900+ mV) your in-car O2s are responding
more to heat than mixture.

 

Hey Phil! Asking me different questions on both boards?!?! COT is still enabled since I still have cats, I thought it was preferred to keep it enabled. I'll answer your questions on the other board later.
