check out my vafc settings after wideband install
I got my wideband in today and was able to fine tune my vafc settings. I have a 99 si with a vortech supercharger at 8 psi with 440 injectors.
Before the wideband, settings were as follows
rpm low & high
1000 -40
1500 -40
2000 -39
2500 -39
3000 -38
3500 -38
4000 -37
4500 -37
and so on....you get the point
and i was gettin a high of .53 bar on my vafc...stayin around .49 as a high most of the time.
With the wideband here are my street tuned settings
rpm low hi
1000 -47 -40
1500 -46 -41
2000 -43 -41
2500 -43 -41
3000 -43 -41
3500 -43 -40
4000 -42 -40
4500 -41 -40
5000 -39 -39
5500 -39 -39
6000 -39 -39
7000 -40 -40
8000 -40 -41
9000 -42 -42
now i am gettin a high of .55 bar.
these settings yeild me about 14.5 out of boost and 12-12.5 in boost with it goin to about 10.5 at 7500rmp.
I was very suprised at how much i was able to lean it out in the high rpm's. When i first got the wideband in and took it for a test drive, from 4000 on at full throtel, the wideband just said rich. as rich as it goes is 10.0:1. I feel like i picked up quite a bit of top end power, and im not really gettin traction at all in 2nd (shitty tires)
Anyway, i just wanted to share
