First WOT run with auto xray. Opinions needed.

[AMinor65]

Alright! I finally know what my car is doing. Here's what I got. Car was thorougly warmed up.
Intake air temp 62 degrees
B1S1 o2's from .910 to .925
B2S1 o2'S from .895 to .93
LT1 -6.3%
LT2 -6.3%

(Edit)
Forgot to mention that I'm using 93 octane, and have my mini-afc set up to transmit 99% of the maf signal.

Looks like there's a little room for improvement. One thing that concerned me was a drop from 24 degrees advance to 18 degrees at 4818rpm in 3rd gear? Opinions are welcome and wanted on all results.

o2's are a little high, especially for na. I shoot for .87-.89 or so.

Interesting that bank 2 is more variable than bank 1, higher and lower. But about centered in the same range. How many miles on your sensors?

LT's look ok to me.

I don't know what's happening with your timing, unless you had some kr coming in. Can you log kr too?

It's cool to be able to see all that stuff for the first time huh!?! [img]smile.gif[/img]

4800 rpms in 3rd gear is about 110 right

i think its cause you know how the car shifts to 4th close to 5K in od inless its in d


leave it in 3rd gear and try it

Yeah, it is pretty cool! Okay John, I'll shoot for that range. If they're stock o2s, they have about 73,000 miles on them. No, it can't log kr without upgrading it. That's another 140 bucks. ...Nope.

Jason, I'm pretty sure that I was nowhere near 110, but I'll take your advice, and leave it in third next time.

Jason, you might be on to something. Went back to check my auto xray. When my timing advance was 24.5, my "reported" mph was 102mph at 4626rpm. When it dropped to 18 degrees, my reported mph was 109mph at 4818rpm. Go figure.

I was just wondering if it was getting due for new ones... Since one was reading a little wider range than the other. I don't know the life span though.

I know some cars are supposed to be changed at 90k. I have 82k on my '98, and still have the stock sensors too.

I'll keep that in mind to do later this year. Thanks again for the response.
