Headed to the track in a bit and can not datalog my wideband analog inputs on my tuning device. What is the target o2 readings for wot in boost pulls? 860's is what it showed on the log and glanced at the gauge showed 11.3 which the gauge reads high so it's actual probably 10.8-11 on pump gas scale. I need to lean it out but it seems cause I'm adding some vp 110 fuel when I get there.

Thanks iin advance!!
 
I need to log actual af to get this thing right. I ordered another programmer and should be here tomorrow or Monday. The car was pig rich in the mid fuel curve 900+ and 830-860 in the upper curve. Would not come up on the 2 step either becase I had tps voltage activation set to high at 4.8 volts where 4.7 is max(just confirmed with multimeter). Had one ok pass but very poor 60' 1.75 7.21 @ 102.7 mph. Back to the drawing board I guess.

. Why only 1/8th mile? These cars are just getting wound up good then..
 
1:50 is mine. You can see where I lifted. Spun a good ways out. Pump gas timing and weighs 3500lbs with driver.
 
You said narrow band but did you mean wide band? At a minimum I would hope you are using a wide band sensor.
 
I've got a wide band on it but was after narrow band data cause I could not log my analog inputs. Got the new device yesterday so all is good again.
 
Thanks for the compliments! That was like 16 Psi 14-15 timing. I let out of the throttle on take off. The intake temps are starting to get out of control With this 62mm. My engine builder says to go 4 core or bigger turbo and then I can give it more timing if the temps stay under 120.
