tuners:please check my diablo live data I recently installed a 160 stat and upped pe .05 and spark 2.00deg...but it should have had time to adjust by now.
Please, please take a look and give me any suggestions you may have!!!
current settings:
engine temp 183*
fuel (PE) +.59%
spark +4.00
reading at WOT:
LTFT1 .78
LTFT2 0
O2#1 915
O2#2 885
O2#3 915
O2#4 885
KR is always zero
Spark is 22* at idle and 35*-45* at partial to 99* throttle...but goes down to 28.4 when I hit WOT???? By my butt-o-meter, the car doesn't slow down any even though the spark dips to 28.4 at WOT and stays there.
What's going on,
Kyle

well not sure what your asking exaclty, it is normal for part throttle timing to be higher than WOT. You also might want to lower your fan temps a bit to take advantage of your 160 stat.

yea, that was the major part of it. I also just wanted to throw the info in with it to show everything else is around normal(barely rich I believe).
1. Why is my spark so low at WOT, I thought from the factory you should have about 29* of timing?
2. I want LTFT's in the slight negatives, right? how do I get them there and why is one higher?

Stock tune is much lower than that on my '02. I had
to push the Predator tune to +10% spark to see 30
degrees. This all looks like pretty normal numbers,
you can keep jacking the spark forward until you
see KR and then back off a couple of percent for
warm air and bad gas, and stand pat. If you put a
bit more PE you would likely lose that last bit of
positive trimming though that would also make the
WOT O2s fatter and maybe make it feel a little
soggier around town. Just have to try and see
what gives you the best result, there. With more
PE you will be able to stand more spark.

I was hoping for maybe a +2 for that or this type of answer, but I guess your right. Shucks, I guess I just have to race it around some more 
BTW I just came across emarkay's website from another thread, it's pretty funny if you haven't seen it before. Very creative
just click on the "unique mods" link.

Wait, one more question if you don't mind:
How come my O2's are showing to be slightly on the rich side, while my LTFT's are showing me to be slightly lean? Like, if I richened my PE in order to get -4LTFT...wouldn't my O2 be showing me as pig rich
