Yes a bama tune although that prob work out ok for nitrous on 2011. I always like it rich on my 03. 03 is 11.75 w s/c only and varies w nitrous, not exactly sure why it does. Starts off 11.75 drops to 11.0 at 6.5k. Prob due to progressive controller idk. Its worked out ok. Pretty cool you can see commanded a/f and actual a/f and lambda if you wish.

I see that one spot on your datalog is 12.03, but the rest looks to be about 12.1-12.2. It probably needs about 5% taken out of it. I am assuming this is a 2011 since you're datalogging wideband? PM me with some info, so I can take a look into it.
69gt4speed, how about you? Which vehicle? PM me some info.
We're getting literally hundreds of dyno sheets and datalogs back every week and seeing 12.5-12.9 on most N/A Mustangs. We command 12.8ish on most 96-2010's and then 12.5-12.6 on most 2011's. We use 14.4 as the stoich point on most 05-10's, 14.08 on 2011's. Make sure that is taken into consideration if you're looking at the STFT's to determine commanded.

Are you going fatter 2.5 and 2.6 because the 2011's move more air and run leaner because of it ???
Hi Jimmy ! Jack Frost here.........hope you're loving the 5.0
just got done tuning and dynoing... laid down 416/360's... and the a/f was 12.2... a little low but i bet an extra degree or too of timing would solve that and add an extra few ponies
Howdy Jack :rockon:
Luvin my Mustang,, Going to e Town tomorrow,,,wish me luck!!!:beer:
Yes, his graph does say CP: uncorrected though. Guessing there not sae numbers, but thats not the point on this thread.:beer:
How much timing are you running now?
I've been a bit skeptical abouth the A/F readings from my dashhawk so I ran a log on my stock GT500. I have an Innovate LM-1 but no bungs welded into the GT or GT500. I feel that the readings are spot on and a true indication of the actual A/F. The GT500's A/F are low 11's to low 12's. Here is a copy of that log.

We found that with the 05-10 3V's, they made a little more power at 12.8-13.0. However, the 2011's from all the testing we've done, they actually are happier and making the same or a TINY bit more power at 12.6ish.
My Jon Lund tunes between 12.5-12.7
As said above. around 12.6 is where these motors like to be.

havent looked but my tune looks to be pig rich cuz its starts at 12.4 dips down to 12.2 and then jumps back to 12.4 till the end of the run
That's about right.
we've got mine set for 11.0 to 11.1 roughly that is based on the .80 reading the logger is seeing times the 13.77 stoich on the ms109 i'm running.
12.2 is not pig rich. 10.2 is... lol.
12.2 is rich, yes, but not bad at all and on the safe side of things.

^ What he said..
12.2-12.4 is about 2% rich. That's really not bad at all.
Beefcake, for example... his tune is rich... but he's also running a fuel with a different burn point and a shit ton of nitrous (I think a 200 shot?).

Are Readings from Aeroforce gauge and tailpipe sniffer close?
Most readings we see here are from Tail pipe Sniffer

ok so its not pig rich, but its rich for me but then again im in a climate where it gets damn cold and dump hot so many i should just leave it. What am i gonna gain by altering it? 5 hp more... not worth it
not even that, i would say...lol
