First Time log!!! help please quickly!!!!

[squeak10686]

Tell me what you guys think of this... WHY THE H*L* am i running such high amounts of timing... when i let it idle it sits around6-8... is this bad that im running this high of timing...
they were done on second gear pulls, due to not having enough space...

RPM O2V Timing
2624 0.85 24
2848 0.87 20
3196 0.91 17
3588 0.91 17
3992 0.93 18
4432 0.93 18
4864 0.97 19
5280 0.97 20
5660 0.97 23
6036 1 24
6388 0.97 26
6700 0.97 27
6968 1 28

Any help given is great
Thanks andrew

Obvious first...your car is a WOT and your TPS is somewhere near 100% right? If all is good there, I would check your fuel pressure. I see you have the B&M regulator so you probably have it turned up. If its too high and your leaning out your afc too much that can cause very high timing.

Check that tps signal like /\ said. If that's fine, you can try injector compensation via eprom chip or a REAL AFPR that can lower fuel pressure and you can lower your fuel pressure and corrct with the SAFC.

what about just turnign up the boost, im only at 10 psi???

 

[98spydert]

If everythings a ok, the car should run fine at low psi. Not enough air is not the problem

Well, it is related to airflow.

The ECU uses mass airflow to determine which timing map to use. More airflow = less timing and vice versa. Also having little or no knock will put you on the highest timing map. You might want to find a place where you can do a third gear pull since it will shake out any tuning issues. A second gear pull will usually show less knock than a third gear pull. The log looks good, so it should be safe to raise the boost a little. Just make sure to turn it up one psi at a time and do more logging so you know when you've reached the limit.

I did another log and this was on 14 PSI

3120 0.95 10
3340 0.95 11
3572 0.95 11
3804 0.95 12
4036 0.95 11
4268 0.95 12
4504 0.95 12
4732 0.97 13
4964 0.97 15
5200 0.97 15
5384 0.97 17
5604 0.97 18

^^^^ semi cut me off so i couldnt finish, and i was on my way home.... i think i can still turn up the boost, plus look at my 02 sensor, i need to lean this bi*** out some more dont I?

Do not go off of a narrowband O2 reading. Lean it until it pulls timing, and then richen it back up some (so it doesn't pull timing.)

cant you get a * narrow * idea of how the car is running through the narrowband, how does that log look, my timing is still pretty high, is that bad???

 

[Coup D E'Tat]

That log looks decent. There are a few spots where the timing bounces around, and you don't want this. You want a nice, smooth rise in timing.

The timing is actually a little low if you ask me. I usually shoot for around 20-21* peak on pump gas.

You can either lean it out more at 14psi or turn the boost up. Turn the boost up until you have a good O2 reading something closer to lean. Your timing curve is fine, it takes a steady climb upwards and I don't see any sharp drops that would indicate it being pulled or "knock". I think once you raise the boost your timing will look a little difference. Do that, post another log and we can go from there, otherwise everything looks pretty good.
