What do you guys think? BTW car has a stock tune.

you never put the accelerator right down to the floor.
to do a proper log you need to go WOT from about 2500 rpm.
i.e. Accelerator Pedal Position (APP) will read 99% and the Throttle Position (TP) will read around 75%
edit: you will also need to log the following parameters in addition: BAT, Calc. Load, LTFT (helps show the car is in open loop when it reads as 0.16).
and you can get rid of vehicle speed because that's not doing anything.

Maybe I loaded the wrong log because I definitely floored it both gears. I will check into that tomorrow.
Thanks
I should've read your post better before diving into the datalogs. I looked at it and thought WTF, this can't be more than the stock tune. And well, it is.
Looks fine for a stock tune. Now turn it up! I see tons of potential, here. :-)
Oh and Chris, that is a WOT pull. The stock tune just doesn't open up the throttle all the way.
So what is a safe boost target for me? Only mods is a SRI for now but more stuff on the way. I want to squeeze as much as I can out of it for now lol. My boost target is 16psi right now holding steady but I was hoping to go for 17.5-18psi.
Yeah you are right... but its so exciting tuning on access tuner with this AP. When you and others said its the best bang for buck you werent kidding. And yeah... I am running winter tires now lol. Spinning like a mofo !
Also, noticed the boost levels are a bit more sporadic but I am assuming that has alot to do with it being winter and the air levels being more dense? I feel like the speeds optimal comfort zone is between 12-16degrees but I could be way off.
edit... I think I messed that up... less dense air (high altitude or hot air in 100 degree heat), and humid air (less air molecules due to added water) decrease our boost and engine performance. More dense air (sea or below sea level, cold air), and dry air (maximize air molecules) increase boost and engine performance. Do I have that right?

So that's what the stock tune looks like... Boost really drops that much eh? I've never seen a stock tune log before.
I guess, with the AP you can let it hold a sustained boost of perhaps around 16psi till red line right?
And your analysis about cool air and hot air sounds about right.
Like Chris said, I'd stick with the "choon" you have right now.
I take it you still have the stock HPFP?
One thing to take into account (especially in the winter) is what loads you are hitting as opposed to boost. For the same amount of boost, you will hit higher loads (and make more power) in the winter. Airflows in the winter can increase by 20+g/s; if you have the stock HPFP, you may run into fuel pressure problems in the winter whereas you wouldn't in the summer (at 16PSI).

This is the latest log on my current tune. Is anything out of wack?
I've mentioned this to another member before as a suggestion, when saving and then posting your logs, it's a good habit to have the date, tune and fueling listed.
example: 11Dec08 - Stage 1 + SF 91 Oct - Log 1
it makes it very easy for anyone who looks at it to right away know what they're opening and what to look for.
couple things I noticed.
- your fuel pressure dips below 1600psi from 3400 - 4000rpm, as low as in the 1400 range, is that terrible? someone with more experience will have to comment, but from what I hear thats how it starts in terms of the fuel pump going. correct me if I'm wrong.
- your WGDC is maxed out from about 5200rpm and onward
- what AFR are you targetting? have you adjusted the tables or just using the stock values? It does lean out a bit in the middle there when compared to a V210 values
- slight knock as the turbo begins to spool, but my car does that too, and then some...

I will definitely add that info next time. It is a stage1 + sure auros V2 sri 91 oct
I noticed the fuel pressure drop as well but I also dont know if thats terrible lol... definitely not good.
I havent adjusted the afr tables so they are stock for now.
I know that alot of people who post logs show some knock but its usually .35 -.7
I am going to start saving for a fuel pump lol
Some people say a pressure drop to 1600psi is acceptable.
I say, any pressure drop is unacceptable. You're not always watching fuel pressure when going WOT so there's no guarantee things are always running like they should.

Here is my latest log
quite a bit of knock
A partial throttle log (max 60% throttle) doesn't really help ppl see any problems if there are any...
Furthermore, can't tell if you're being sarcastic about knock...
However, if you had the throttle pegged to the floor in this log...

I was in fourth gear and I punched it at around 2000RPM. I saw knock up to 2.45 around 5000RPM.
I was definitely WOT
I asked this question already, and BlueStreak pointed out that the stock tune does not open the throttle fully
I don't see any knock in that log
Shit I put the wrong log on ... try this one fobio... sorry bout that

that knock is something to worry about, do you consistently get it at that point every time?
as well, you want to log AFRs
Oh damn, that sucks. Oh well, I stopped reading the Speed section because according to certain people only speed owners are allowed to even look at that section.
