Hey guys.

I know this is a terrible run. I went to the highway but forgot to click everything to data log. So I did a quick run on a local closed road.

I have K&N intake and CNT cat back. Nothing else.

Is the AFR around 11.5-11.8 at WOT bad for a 2012?

I ran the Stage1 + SF93 v400 map.

I can also try the Stage1 93 v400 if need be.

If someone can check this data log for me and let me know if its ok or if I should try the other map.

Thanks,
Ryan

 

your afr's are about right they should be 11.3 at wot but i cant view your data log on my work computer ill check it out when i get home and see if i can see anything that doesnt look right to me and im just a general knowledge person im not an expert on tunes

 

I have two more runs to look at.

This time 46 is a good pull in 3rd.

Then 47 is just a normal cruize at like 40mph in 5th. Just trying to see if those are safe numbers just driving normal.

Also the tune said it should be around ~25psi of boost. I am barely at stock.....What can cause that?

 

Cobb also told me to try the stage 2 maps.

As you can see...the boost is still staying at stock-ish numbers. Peaking at like 21.8.

Everything else seems to check out ok also, so I dont know whats wrong with this.

 

Looking at my logs my AFR is around yours at WOT. Infact mine hit as high as 11.91

Not sure if that is good or bad

 

Higher temps will generally cause lower boost levels, then they'll rise as it gets cooler outside; don't worry too much about peak boost values. If your car is running good and not knocking then you don't really have anything to worry about. Basic bolt-on pump gas tunes are more forgiving in the sense that excessive knock values will clue you in to a problem such as lean AFR's or overly advanced timing. Even on my car I don't have any gauges, I just watch for my knockCEL to flash. Speaking of which, 102F yesterday and my car was still taking WOT pulls like a champ

I generally look for AFR's to be in the low/mid-11's on pump gas for a conservative street setup.
