Finally got my logger

[jaktheripper]

I finally got my Pocketlogger today and this is my first run.(3rd gear pull). People with experience in logging, do these numbers look in the 'ok' range? Any advice on other parameters to run would be appreciated too.

Your timing looks horrible. Log Timing, O2, Inj P/W, RPM.

 

[jaktheripper]

I've heard you should be shooting for around 15 degree timing at WOT. Do my lower numbers mean I'm getting knock or what?

 

[sypderdude31]

Log the following on a 3rd gear WOT pull:

RPM
TPS
Timing
Bank 1 O2
Airflow

Ya your timing looks like hell and air temp means jack sh*t. Log the parameters mentioned above and throw them up here to take a look at. How much boost are you running? What kind of injectors? Done a boost leak test latley?

 

[jaktheripper]

550 injectors...Haven't done a boost leak test, but I'm getting a FMIC in about 2 weeks so I'll get everything straight then. Could that be the cause?

 

[eyebrowski]

How much boost are you running? Probably not...

 

[jaktheripper]

17 psi, but it spikes to 19

 

[eyebrowski]

What are your AFC settings? Thats probably too much boost. Try turning your boost down and see if that cleans up your timing.

 

[jaktheripper]

My AFC was tuned by Buschur Racing, so I don't know the exact settings. Why would this be too much boost, just because of the stock sidemount?

 

[eyebrowski]

Why would this be too much boost, just because of the stock sidemount?

Yes, or an insufficient tune.

I would really check for boost leaks and get a low boost log.

 

[jaktheripper]

Well since I'll be installing a FMIC within the next 2 weeks or so I don't want to take it apart now to preform a boost leak test, especially since I don't have the materials. I'll just drive it easy until I get the FMIC, then make sure everything is tight.

 

[eyebrowski]

Intake pipes are only one place that intake leaks can form. They are also very common at the injectors and intake mani gasket, and since you have replaced the injectors I think it would be very beneficial to do the test. You only have to remove the intake pipe to do it. Even if you don’t plan on doing it now it is a must when you install the new FMIC.

 

[jaktheripper]

I'm having trouble getting this timing where it should be. Currently my SAFC is set at -15 from 3k-8k on hi throttle. I have a big 16g set at 19psi. I know every car is different, but this isn't too far off from where people with similar mods set it right?

 

[LandoAWD]

every car is different

Bingo.

Have you tested for leaks yet?

What do you mean "getting this timing where it should be"?


What do the logs look like now?

Have you changed to the FMIC?


If you want accurate help, you have to throw us a hint or two and not be so vague.

 

[eyebrowski]

Have you tried lowering your boost to get the timing in spec?

 

[jaktheripper]

No I haven't switched to the FMIC yet (doing it this saturday) but it's really cold out and I just made one pull so I figure that wasn't the cause, I could be wrong though. I have finally made my leak tester so that portion is done. By getting the timing where it should be I mean it progressively advancing to redline instead hovering around 5-6.

 

[91gvr4]

Ok, i hate to be an asshole, but take some advice. Have you done a boost leak test, NO. Then do it. Most likely your Fmic isnt going to correct the problem if you only doing 1 run. Fix your problems dont put them off. By the way your timing is horrible, you may also want to invest in a new knock sensor.

Later,

Mike

 

[jaktheripper]

First of all, if you read my post above you see that I did do a boost leak test. Second of all 2gs dont have knock sensors. And I'm not putting my problem off, hence me asking for advice so I can get it fixed as quickly as possible.

 

[LandoAWD]

Incorrect. You said you made a tester.

2gs do, in fact, have a knock sensor.

 

[jaktheripper]

Well I meant I finally made one since I've been meaning to for a while, so of course I'd test it. If 2gs have a knock sensor then why can't we log it?

 

[eyebrowski]

Well I meant I finally made one since I've been meaning to for a while, so of course I'd test it. If 2gs have a knock sensor then why can't we log it?

Yes they have knock sensors, what do you think gives the ECU the signal to pull timing? No loggers except for DSMlink have been coded to read it.

PLEASE
Turn your boost to stock and zero out your afc and make a log for me to look at.

And you didn't have ANY leaks when testing it?

 

[jaktheripper]

I tightened a couple bolts on the upper intercooler piping before testing it, so they might have been leaking before. I'm giong to do another test when I have the bumper off for the installation of my FMIC. If I zero out the AFC wouldn't it run really rich with 550 injectors?

 

[eyebrowski]

Not with your mods and a 16G. I don't really care so much about making your car run rich I want to see if you can get that knock under control. If that works slowly increase your boost while tuning it at each boost level until you find the boost level where knock begins to show. You have way to many variables right now and need to start narrowing down where the knock is really coming from, is it a tuning issue, insufficient IC, bad knock sensor, boost leaks, etc...

 

[jaktheripper]

Can't you get knock from being too rich as well? I'm installing my IC this Saturday, so I'll be able to better check better for boost leaks then run another log. That will completely narrow out boost leaks as well as insufficient IC if it's still pulling timing.
