o2 readings
o2 readings
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....
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

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.
