First Logs, any help would be appreciated

[BlackbirdOfPrey]

I did this run set at about 14 Psi, I also did another log that looked really similar. Any help figuring out why my knock shot up would be helpful along with explaining some of the other weird numbers. BTW is it odd that my fuel trims are all at 130% +?

Looks like your going lean at 3700 and up....if you are on a stock turbo and fuel system, i would check everything to do with fuel. (filter, pump, injectors, etc) Are you sure you are not boosting higher than 14? Maybe rewire your pump if stock?

 

[BlackbirdOfPrey]

I am on the stock turbo, stock fuel (everything, pump, injectors etc....) and it is holding 14psi solid, not even spiking on initial boost. Is 14 psi too much? I was told I should be able to run up to 15 without running too lean. At Idle should my low fuel trims be at 130%? or is that an indication of a problem, that seems a little high.

 

[slickster]

14 should be fine. If everything is stock aside from your k&n and mbc, I would suggest a new fuel filter. Does you car idle fine? how about just normal driving? highway cruising? If it does ok at those times and just screwy at wot, then i would say its probably your fuel filter. Maybe your injectors are really dirty. I would think one of the two.

 

[swarm]

just a tip... leave the fuel filter on the firewall when you break the connections loose.. or you'll be sorry.. hehe.. i'm speaking from experience, i am now looking for a double flare tool

 

[slickster]

....same here....loosen the bolts before taking the bracket off....damn i cussed ALOT!!!!

 

[iamtall77]

You might even need a longer handled wrench to get that thing off. Also, it's a good idea to put some thread tape on the lower fuel line fitting. It's a lot easier when the battery is out than trying to fix a leak after startup. Also if you can hook up power to the system, do a fuel pump startup with the logger and presureize the system bofrore sticky the brick back in. By brick I mean the massive chunk of battery most of us have. Let us know if the situation improves. By the way, when does the MAS run out of reading room? I noticed that the readings on the above log stopped pretty much at 1600Hz. How far does the stock meter go? Just a thought.

 

[BrokenTsi]

1600 is all the logger can read. the actual number the ecu sees is much higher. log injector pulse as well. You would think it was lean because of the knock, but his o2 volts are fine. .86 is not very lean at all. That's about what i run when im fully tuned with zero knock. But dont tune to just o2 volts. I agree with the fuel filter theory. I changed mine the other day. couldn't even blow air through it, changed the filter, and voila, back to runnin 12's again.

oh yeah, dont let them scare you with the filter change. If you have to cuss and swear, and take more then 10minutes of your time, then there is something wrong with you. If you cant get the banjo bolt off the top, take the whole damn thing out with the fuel line to the fuel rail, put the filter in a vise, and crack that s.o.b. off. and get double flare wrench too, much nicer.

 

[swarm]

the bottom one is harder.. because it's so difficult to get to

it's not extremely hard, though

and you're working on a gen1... we're gen2.. gen2 is much harder than gen1...

I still seem to be knocking at upper rpms, now that I've eliminated overboosting, anyone else have suggestions. One other thing I noticed is that if I set it for 12psi, once I got to about 6k the boost would drop slowly down to about 10psi and hold, is this normal?
