02 volts?

[vettekilr]

At wot my 02 volts are 940 to 950,i thought they should be around 700 to 750?Could someone set me staight on this,and when i let off the gas sometimes it goes to zero is this norml,i really dont understand all of this?please help.

O2s should be anywhere between 780 to 820 at wot. What injectors are you running and what fuel pressure are you running at. I see you have a RA 93chip fuel should be set at 43psi. Plus when you let off the gas the numbers will drop that is normal.

if your o2 volts are that high at wot
that generally means you can either run more boost in order to lower the o2's down down at WOT
or you could turn down your fuel pressure a pound or 2 if u have an adjustable fp regulator
that is if you are fine with the set amount of boost you have
or if you do not have an adjustable wastegate actuator

my fuel pres.is at 43,i currently have 009s in it awaiting te60,thdp,my boost is only set at 16# now,i'll turn it up a pound or two and see if i can get it around 800 or so, thanx

Now wouldn't increasing boost also pump more fuel since the FPR is also increasing fuel pressure??Also What kinda scan tool are you useing? You don't want to increase boost until you are absolutly sure you can monitor knock correctly.

I'm useing an autox-ray scanner,afpr.

I threw red's chip in the garbage(not literally) cause the fuel curve was overall too rich and too much timing. Couldn't get more than 19lbs without knock and even turned FP down to try to lean it out. Went to a Lubrant chip, which has less timing and less fuel, 21#, no knock at 45# FP.

I keep hearing the samething over and over about his chips running rich,he lives close to me and i always used his chips,what are some other chips?

I am switching over to a tran+ and extender within the next couple of week's so that I have more adjustability.And yes I am running one of his chips right now also.

I heard it too, and it's true. Jim testa, Jay carter, Joe Lubrant, all make chips, and you can get softwware to make your own.

I have been running Reds chips for a while and i have never had any problems. 009s injectors are a pain to tune but once you have them dialed in they work Great!! Just call Quad Air and talk to Red and let him know what problems you are having and he will take care of you.

I think that scantool might read about .100 higher than most. So your 940 is actually 840 to the rest of us. You might ask Red about it.
