I installed my AEM Wideband. I was wondering if 11.4 at mid rpm range going down to 10.00 at higher rpms is running to rich? I have an 03 w/ dynoflash, and the rest of the mods are... catless 3", intake, 264.272 cam's.. would love to get some opinions? Never tuned cars but it seems like i am running to rich at high throttle and im worried it may cause my plugs to foul... well better then running lean. thanks ahead of time....
i tried searching but im just looking for quick and easy input

 

10 is to rich

 

I remember reading something on my Autometer gauge instructions before... I was juts looking at them for the heck of it. Now, after doing some good searching; here ya go!

11 is good, 12 is dangerous

 

If you cant open it, go to http://www.download.com and do a search for 'Adobe Reader' and download that so you can open it. The full name ofthe program is Adobe Acrobat Reader... You probably have and know that.

 

You did not give a list of parts installed in your car. So one can only assume. By the type of question you are asking, that tells us you may have very few parts in there.
11.4 a/f's is allmost perfect. Specially in mid-range. However, 10.0 at hi rpms is very rich. I would say you want to stay around 11.4 a/f's at midrange and down low, and 11.4 to 11.1 by red line. That will be fine on pump gas.

 

thats better than my 11.6-11.7 and almost 11.8 at times at redline for me , I need a fuel pump and you need a better tune.

 

x2!! Don't go kaboom... I woulnd't let thos A/F #'s go higher.. and I wouldnt let the A/f on the guy that started this thread ever go less then that, infact go up.. lol Apexi SAFC or flash!

 

you are talking about full boost. I believe the big name tuners like to see 11, other tuners go leaner, like 11.3 or so. with water injection you can go leaner still. but whatever you do make sure your knock retard is dialed in, for those bad hair days.

you can got 14.7 + or - in cruise all the way.

 

10 in the high rpm is stock rich. Your car should be in the 11-11.2 in the high rpm. By high I mean from 5500 on to redline. Was this a custom dynoflash or mail-in? Was your dynoflash tuned to your mods? More than likely you are not making the power you were supposed since you are running so rich up top.

 

was a custom dynoflash, and it was tuned with my mods... i figured i was running rich before my aft went it in by my burnt bumper... but al is a great tuner so i cant wait to go back and get it retuned w/ alky that i just bought from Ultimate CC

 

yeah its rich, but safe. I know the car is usually lean down low and it richens up as the rpms climb. Just get another tune. You should be in the low 11's up there.

 

all tunes conservative...so you don't blow isht up
