Another logging question.

[bluetlr2001]

Ok im new to logging. First off im not sure which are the best to log im using obd gauge software. So far im logging rpm,tps,timing,o2-1, And my short and long fuel trims. Another question I have is today i was watching my logger and in third and fourth it felt like i hit a small fuel cut and my timing jumped form 33 to 3 what does that mean, im pretty sure it aint good.

 

[bluetlr2001]

Oh yea i was running 18 psi when it done it and i crept dowm to 15 after it dropped timing.

 

[bluetlr2001]

Come on can somebody give me some advice. im wondering if it is fuel cut or not since my timing drops. Ive done a boost leak test and cant hear anything. Somebody please help.

Well it could be your gettin alot of knock. And you can't hit "small fuel cut" when you do you'll know it because you'll probably hit your face off the steering wheel.


Also, Are you running a GM maft setup because I see in your profile that you have a RFL. And bumping threads is a good way to get them closed.

You shouldn't be hitting fuel cut with a 190 and a rewire. If your still running the T25 18psi is a little much for it. Also when doing boost leak tests you should spray soapy water because just cause you can't hear it doesn't mean theres not any leaks.

-Adam

 

[bluetlr2001]

Nope wish i was running a gm maft but dont have the money yet. But i know its susposed to be better to recurculate the bov but i tried it with my greddy s and couldnt tell a difference. And ill try the soapy water trick tomorrow. And I didnt know about bumping the threads thanks for letting me know that to. And is there a way to check to find out if it is knock. And i know how fuel cut feels and its almost like that just not as bad. And again thanks for letting me know about buming th threads.

The fuel cut feel might be because your not recirculating and your running rich. Im not sure how to read knock on 2g's maybe someone else can chime in.
-Adam

 

[bluetlr2001]

Ill try the recurculating again tomorrow and the water trick. Thanks

 

[Spooling99]

Anytime. But there isn't away to recirculate the RFL I believe

 

[bluetlr2001]

The make a kit i think bu ti could be wrong but i do still have my greddy that ill throw on it for now and see what happens. And another thing dont know if you know about this but i was reading and most peoples timing ive seen runs around 14-16 at wot. And mine runs around 14 normal and moves up to 33-34 at wot.

you sure? WTF

can you post a copy of your log for us to see?

Heres a log from tonight at 18psi. 2-4 gear run, let out in 4th

Rpm Timing fuel trim o2
1360 6 0 800
3374 3 0 980

2024 28 -16 860

Is this good or bad.

 

[PieEyedPiper]

Looks absolutely terrible.

Logs aren't performed like that usually either.

When making a log (and be safe about it please), be rolling in 3rd at around 2500rpm and then just gun it. Wind out 3rd gear until 6500-7000 rpm and back off. Log only rpm, timing, tps, and 02 voltage.
Post back and we'll better be able to help you.

I suggest you run no more than 15psi as it is though. Start there and we'll see how we can help.
good luck and definitely post back!

 

[bluetlr2001]

Thanks for the quick reply and in the morning ill give it a run on the way to work then post when i get there.

 

[bluetlr2001]

Ok so i done a log like you said and here it is. And i hit fuel cut a couple of times doing this.

so good or bad

 

[bluetlr2001]

Ok heres my recent log ive done at 15psi. I think theres alot of knock but im still new to the logger so help me out here. And i know im running rich to so dont know if thats causing knock either. And youll see were my rpms dropped i had to back out the throllte a little and ease back in because it just nosed over.

Your timing is -6..... I think your probably geting alot of knock right when you go WOT. Turn the boost down and try another one. Also check base timing
-Adam

 

[bluetlr2001]

I was going to check base timing but cant seem to find the plug thats suspossed to be behind the battery to ground to set the timing. Plus ive tried it at 12psi and it still goes to negative timing. Do you think it could be a bad knock sensor or just to sensitive.

 

[Spooling99]

I believe if its bad then there should be some "goo" or something coming out of it. check for that.

 

[bluetlr2001]

Ive read that on the 2g that they were selled better than the 1g and that they wouldnt leak. Because its running so rich could that cause knock. And if so do i need to invest in a fuel controller?

 

[Spooling99]

You dont have bigger injectors do you? Did you ever find a way to recirculate your BOV. I dont see how you could be running that rich on stock injectors.
-Adam

 

[bluetlr2001]

Ive recurculated with my greddy bov but yes im still running stock injectors.
