i just got my widband installed 5th grear at 70mph in 14.4-15.2 and wot it's 11.2-12.0.

 

Well when it's hot out my AFR is like 10.2 (super rich)
When it's nice and cool out I see 11.2-11.5ish

5th gear @ 70 is the same 14.4-15.2

 

hey he should worry bout leanin out with that 2.79 on stage 2 and his duty cycle is off the hook too

 

if you're seeing 12.0 at 6500 and above, which you are with the 2.79. your injectors are going static. this is bad.

my a/f is 11.4 all the way up.

2.8 and 42's

i have the magic touch

 

11.1 til 5k then from 5k to 7k 10.0 (safe tune)

 

i dont know if id call 10.0 from 5k to 7k "safe" id call it "dangerously rich"

 

yeah 10.0:1 is bad for EGT's
I run 11.4 all the way to 7400 with my 2.55 setup.

 

Mid-low 11's @wot

 

The first week of August i will be installing stage II w/a 2.9" pulley. I live in ohio n was wondering what kind of A/F ratio numbers i should expect to see. I dont want to go boom since this is my daily driver. lol

 

~12.3

 

I have mine set to start at out at 11.2 (rich for good torque) at 3000-5000, then it leans out to 11.8 from 5000ish-7000 works great for my set up. If only the piece of **** pistons could hold up to it.

GOT DAYUM!!!!

 

a little richer under 3500, maybe .5

 

12.5

 

you don't count

 

Not fair Mr. N/A!!!

 

lol , i like being n/a , one day ill get a blower ... one day

 

hell, try the STS turbo, tbyrne made one with gobs of power...I ran him and he laughed all the way...so far I couldn't read the license plate anymore.

 

What cam do you have? (specs?)

**** that. Pro charger, who cares if it don't make power at low rpm, its a V8!

 

true, torque monster if done right

 

ok at 10 pst 50% throtle im seeing 14.1 to 15.0 i talked to a performance shop he said that it was fine. i think it's way to lean. And one qustion can you use any tuner to tune your car or just hp?

 

When your not in PE mode 14.5-15.0 is fine. When I was running a 2.6 pulley I ran my AFR at 11.5-11.8. With the 2.6 I never felt comfortable going above 11.8.

 

car won't go into a richer "mode" til A, throttle is past a certain point, or B boost is past 55kpa, or C. rpm is passed. Which would put the motor under a high load, needing the rich condition, at part throttle and cruising speeds that's all the engine needs when not under a high load... the wonders of fuel injection.

 

ok so you are saying it's fine if im getting on the hwy at part throttle 10 12 psi and it's at 14.1 to 15.

 

yup.. I hit 15-16 psi at part throttle at a 14.xx afr and no knock onceI go above 75% throttle... 11.4:1 afr

 

yup.. I hit 15-16 psi at part throttle at a 14.xx afr and no knock onceI go above 75% throttle... 11.4:1 afr
