Hello guys,
I've been playing with my car for these last 2.5 weeks trying to find her sweet spot on pump gas before heading out to the track (it's tough for me due to work). So I'm doing much of my tuining late at night on empty streets late at night, and here is what I got:
For some reason I am getting O2 readings in the 790 to 810 low and 725 to 765 high, often in the 742 range for most of 3rd gear and NO KNOCK
My static fuel has been in the 45psi to 48psi range but it seems to like the 45psi best. My boost is set to 17psi but I've seen it creep up to 19psi on a few occassions and NO KNOCK whatsoever on 93oct Chevron gas. TPS is set at .42 idle and 4.78 WOT.
Ever since I changed my O2 sensor from the Denso to the Bosh, my car has been running like this. I felt that it was a huge sin to run this amount of boost on 93oct with readings in the high 720's to mid 740's in 3rd! The Denso's was getting old. I bought the car with it, so I say it was at least 2 years old.
On two occassions I checked a few plugs right after a run and then changed then later and they all had a nice brown coloring to them...NO white coloring it all after the runs and at home during the swap.
Has any one else experienced or are experiencing the same?
Here is my set up:
TT chip 93oct street
TE-44
3" THDP w/dump
Scanmaster 2.1
340 walboro hotwired
50* injectors
Hooker 2.5 dual exhaust
D5 stalled to 2,800
160*
Stock IC with Dutt neck
Autolite 24 (.035)
Fuel press reg
Thanks:biggrin:
