need help tuning!

[WOP'R]

i jost got my 92 R/T up and running with a 3 bar cal and +40's and i wanted to know: what should my lambda reading from my plx wideband gauge at WOT be?

and also just for the sake of it what should the static (vac line unplugged) fuel pressure be at my afpr??

55 static but cals do vary a bit so you'll have to play.

cool now i just need to know what the reading on my gauge should be...maybe by tuning it right it'll get rid of some of the smoke and help out with the idle

I was just told 11-11.5 at WOT. I just hooked up my wideband,

as simon said i tried to aim for 11.5, you could be go higher actually but 11.5 is a good safe point. I always ran 93oct too, but am now running e85

heres the thing...mine doesnt give out that form of reading as an out put.

instead it gives out lambda wich is 0.68 lambda(0V) - 1.36 lambda (5V)...1.0 lambda is stoich

I'll let you know tonight as mine reads out in both.

Ok, my lamda was .75 at 10.8 af ratio. So I would figure you want around .80

What PLX WBO2 do you have? I have two different models and I am able to get both of them to read in AFR or lambda.

i got the DM-5 AFR...just found the instructions and it says to disconnect the solid black wire to show a/f

you can tune in Lambda or A/F, all it is is this: 1 Lambda = 14.7(as long as its set for gasoline)

so 11.5 A/F = 11.5/14.7 = .7823 Lambda

or say .75 Lambda = .75 x 14.7 = 11.025 A/F

That is an excellent point. I know it is just a lot easier for most of us to get the readout in AFR.

My car actually lost power on 11.ish versus pig rich 10 on the dyno. But the dyno was reading leaner a/f than my wideband does- I am running a cat. My fuel pressure is set at 40psi w/+40s and s5 cal from Cindy.
