Can some one help me figure out what I am doing wrong? I have adjusted both richer and leaner. Seems like if i richen some of this up with will knock more.if i lean it out seems to loose power. When I switch back to stock it pulls Ungodly harder. Like some one is punching me in the stomach hard. Can you help. Here is a log of My stock Log Maxoct table and then my trying to make it pull harder Log.


MAF.elg is my maxoct table

Stock is well.. Stock

Assuming your sig is correct then that timing is way too low.

You should run around 3-4 degrees at peak boost and depending on your setup you should be able to carry around 14-16 degrees up top on pump 93 and 20+psi.
 
Your timing table has no timing in it. So yeah its going to feel dog ass slow.

Your running 0 degrees man.
 
Keep in mind by Editing only the MAx octane table and leaving the min as is. When/If you pick up knock it will interpolate between max and min and actually raise the timing the way things are in the MAF log(which doesn't show really anything)...

Not sure if you or someone else is/were tuning the car. But I would imagine someone kept pulling timing and couldn't figure out why it wasn't helping... ?

Not a lot to go off to say what is up(and I'm not that free to look much more than I did(Quick glance)... But I'm sure the car can get away with more timing as said.

IMHO If you want any real help on your own you are not going to get very far with questions like what you asked in the post above.

Edit... Your WAY lean according to the way you have your wideband hooked up... You definitely have some work to do getting things in check. I'd refrain from doing pull over and over like in the "stock" log.
 
Flash this file on, I modified your tuned timing tables with the factory evo 8 tables.

Few questions, what are your AFR's during your pulls?

Why are you trying to use fuel to tune?

I'd adjust your fuel tables in the DA (only) so that you have an AFR curve you want, then leave them at that (DON'T adjust them). From there, use your timing table to get the power you want. Start increasing your timing curve in 1 degree increments until you see knock, then back it off 1 degree. Also, if you're looking for the most power, and have a fuel system that can handle whatever your turbo can throw at it- remember, more boost and less timing will make more power than more timing and less boost. That being said, keep your timing around 12-13 degrees peak and if it isn't knocking and your Duty cycle is still within reason, start turning up the boost until it does start to knock.

Keep in mind by Editing only the MAx octane table and leaving the min as is. When/If you pick up knock it will interpolate between max and min and actually raise the timing the way things are in the MAF log(which doesn't show really anything)...

^^ This exactly, we need more log information. AFR's, boost, etc. There's hardly barebones in your log and makes it very hard to help.

Don't have much to say as far as the thread is concerned... .

But... .
Remember, more boost and less timing will make more power than more timing and less boost. That being said

I wanted to say I don't at all agree with this statement... Aside from that. It's Very hard to say something like this as it's all dependent on the Setup, Fuel turbo et cetera what works best :|

As well the EDA file you attached is doing the same thing I was bringing to the OP's attention.

Buschur actually proved this as well as Magnus? Buschur and another company did testing to see which would make more power. More boost was the winner over more timing.

And yes, I understand that I didn't touch the minOCT tables at all, but it's conservative enough that he shouldn't have to worry about that for right now, as it'll get him a generic base to start on.
 
I apologize My afrest is very very close to what my wide-band says. I'm running 24 psi on my big16g. My fuel pressure is set to stock pressure and my a/f ratio is at 10.9 on boost a wot tell i hit 4200 then 11:0 on full boost all the way up. I changed my fuel table like that because I was told that it would be best for boost. My Aem Wide-band needs a buffer wire from what I was told. Thanks for your help. Does any one have any videos they could show about timing? I already have the Ecmlink Videos.

No Guessing - if you don't know the answer for sure, don't reply - we don't need you spreading hearsay and/or misinformation. If your reply contains phrases like "I think", or "I've heard", or "everyone else does it", or "my brother's uncle's friend did it and had no problems" - it is not useful. Only post a reply if YOU know the answer from YOUR own first-hand experience. Instead of replying with a guess, post a link to a thread where the answer can be found, or the same discussion already took place.
Not Going to debate this at all... MBT is going to be the point that makes the most power and the biggest thing that is going to come into factor with reaching that is the Octane of the fuel.

I was speaking from MY Own personal experience and giving My opinion on this. Rather then come back with "those" guys proved it. Speak from your own experience. So many things like this are completely subjective anyway and depend on the setup.

The everyday guy with a 16g is going to at least on any normal fuel make the same if not more power on 22-24 psi with higher timing then someone on 30+psi low timing... This is just common sense. Even if you can get away with it on a DD or any car for that matter the gains are hardly worth the extra power for most and in a lot of cases pushing things to a lower efficiency with Pump piss 91 for example is just not feasible.

Sure there are turbos out there that open up and can produce higher airflow numbers at higher PR's... But With what you said above. It just seems to me like every Hairy, Dick and Tom is going to say sure that works... . for the general masses I don't find it as sound advice. :idontknow:

And yes, I understand that I didn't touch the minOCT tables at all, but it's conservative enough that he shouldn't have to worry about that for right now, as it'll get him a generic base to start on.

Key thing about any map that is interpolated... you don't want any kind of drastic changes... :|

I'll leave it too you to decide why that would be... .

Now... back on topic :)
 
Guys this is a updated log now. Should be way better now. It pulls a lot harder but still gotta figure out the timing.
