k well I know the o2 sensors on the car are not accurate beyond a certain point but I heard at wot they should be in the 850-900 range and mine is in the 950-1000 range. I had it dynoed and it said I was almost 14:1 till around 5k where it settled down to 13:1 which is where I want it so I changed the % change at wot vs. rpm table and made it so the numbers were closer to what it was around 5200-5600, was this the wrong way of going about this because the o2 readings got maybe 20 points higher on average....

 

... is this a dumb question or is no one sure or did I not advertise enough

 

That's kind of how stock O2's act. So hard to tune by.
Post your pe vs rpm table and the dyno a/f info and we should be able to get you awfully damn close by looking at that.

 

I cant post my graph but I can give you the AFR in 500 or smaller rpm increments, I dont remember seeing a pe vs. rpm table but ill check again, havent used it much lately. Also how much is there to really gain from going from about 13.8: down to 13:1, and what is usually optimum, I hear a lot of things and I know you'de have to get it on the dyno to get it just right but is there a norm to shoot for? Ill go gather the info and post it. Thanks for the help.

 

% change fuel/air ratio vs rpm at wot
IMHO, 13.8:1 is too lean. Shoot for 12.5:1 to 13:1...right in there should be about optimal. The last couple of cars I had on the dyno liked 13:1 so I'd just shoot for that

 

didnt get around to it ill just post em tomorrow.

 

the dyno pulls had slightly different afr's, my MAF is ported as well so I need to switch back to a stock one but a bolt is stuck on my air box and I cant take it off ....

 

the pe vs rpm tables are stock adn the afr stays at about 13.7-13.8 from 2000 till around close to 5 and starts dropping down to 13 at about 5500, if you need super precise afr's at certain rpm's lemme know and ill grab the dyno from my mom's house.

 

sending you a pm

 

hey didnt recieve a pm, just making sure you sent one just in case it didnt make it for whatever reason. Thanks a lot for the help

 

it said your mailbox was full

 

K I erased my 5 or 10 messages I had built up try again and see if it works if you would... thanks again

 

dunno if you've tried to send one since but I havent gotten any, still interested in what you had to say!
