Safe Boost PSI?
2011 wrx 92 octane fuel (ethanol free) 100% stock except Cobb stage 1 91 OTS flash. Target boost is 15 +\- .08. 45 deg F out and basically at sea level. I hit 16.1 at 6500 rpm. I am a dd wrx guy who does very occasional wot to 85 mph or so.
Want to keep my engine happy Am I in a safe range? Thanks.

you will see + or - 1 or 2 psi. the post important thing to keep an eye on are af ratios and knock. the cobb maps are very conservative. im running almost 22 psi on my 08 wrx(vf52 swap) and have never had any issues. i suggest torqued performance maps. the guy is great at what he does and has excellent support. check out 3gwrx.com for some more info.

Excellent. I will do a log and post up when I can find a safe time and place to do so. I assume car will be at 80ish mph at 6500 rpm? I drove around today with AP on fine knock correction and AP stayed at 0 which I assum means nothing as I was mostly in town. I did hit 50 mpg in 2nd at 5500 rpm and still 0, which I assume is good. Is there an online resource of information to read about what the different AP meters are, why it's important and ideal readings on each of the tests? I know so little and am trying to learn more
Thanks |

Did 3 logs: 92 octane gas at 42 degrees, sea level. All stock 2011 wrx hatch with Cobb OTS 91 Octane map.
i have a big Yakima Skybox 16 on the roof if that matters. 3rd gear 2500-6500 rpm. https://docs.google.com/spreadsheet/...DRmYUl2Q1lSekE https://docs.google.com/spreadsheet/...0pmRUxFa05MckE https://docs.google.com/spreadsheet/...DRzVlhNWG4xTGc Any analysis greatly appreciated. My bias is safety. The car is PLENTY fast for me at Stage 1. Stage 1 is much, much smoother than stock, so providing it's safe, I would like to keep both it, and my beloved wrx for many years to come. |

Thanks Bill! I do wot so Infrequently that I am not worried about being on the higher end of average. I might try lwg map for kicks, though. The video mentioned that an ideal AF Learning # is 0, and target is +\- 8. What is the significance of a steady -3.91?
