Ok Ill post the sheet when I get home.
My only mods are a buget Y-pipe,Cai, And emange Ultimate

My Timing is advaced to 11 degrees above stock and my air fuel was at a mostly 13.4
I have a red line of 7200 rpms. My fist runs was done at 10degrees and we moved up to 11 and seen a 2 hp increase. I had no nock on dyno. the higest knock level seen on the eu logger was 26 at about 7000.

Ok I made peak power at 6200 rpms and then it start to fall off
peak torque was made at 3800 rpms

The sae corrected #s are 195.74 whp and 192.09 wtq

Are these good #s for the mods I have. What would a stock dek make.?
And why did the power fall on the top end?

 

Need to see the graph.

Numbers don't sound great but don't sound bad either.

 

Do a compression test to see if your engine is healthy. Are u manual or auto?

Your catback may be leading to the bottleneck in your engine. I would put one on so you can get extra ponnies.

 

yeah im going to compression check tommorow but I think its good. Im 5speed The vi is open I cheked it on the dyno. Im going to post the sheet in a minute or so.

 

Catback would help, or get a cutout so you dont have to deal with droning.

 

damn I would think a 5 speed would be above 200 hp. You definitely have too much back pressure from the catback. Get some headers too. It will shift your powerband slightly.

 

ok run 1 was done in 4th gear
run 2 had 11 degrees timing
and run three the highest we let the car cool off and it went lean for some reason

 

Dip looks like bad eu revlimit tuning

 

I'm not sure. But you think the VIAS closed and that's the reason why you went super rich b/c there wasn't enough air. I don't know anything about the EU but from a functional standpoint it seems like that is what happened in the high rpms.

 

Grade of fuel used?

 

93 octane im getting almost 41 degrees total timing

 

I'd say those numbers are a bit low, but not horrible for those mods. Engine seal/wear could be a factor (check compression), but also keep in mind that having the cat and catback in place, plus no headers is going to hurt you and especially on the top end. Also a Place Racing style CAI is not ideal for top end either, and what kind of filter do you have on there? I've personally seen differences of about 5 hp on the dyno (on my car no less) just on filter type alone. A bit surprising, but true.

The power peak at 6200 rpms is normal for a stock DEK, and that dip at the rev limit may look worse than it is if it was done in 4th gear (how smooth does the transition feel going through gears 1-2-3?)

Where were those A/F readings taken? ie was the dynojet sniffer after the cat or before it? What did the EU and your Zt-2 say the a/f was... 13.4?

Oh and don't forget wheel size and weight will matter also...

 

Adding to the Guinea pig

Alignment can have an affect on DJ readings as well.

 

Also stock cat + tail sniffer = incorrect AF readings

 

tell me about that. Readings are almost allways leaner than the actual A/F ratio.

 

ok I dont have a cat. I have a test pipe the reading from the dyno to the eu to the zt-2 was all about with in .2

 

Danny I have a k&n filter. I was using my 16 se wheels on the dyno. The transiton on the eu rev is not that smoth in third. But im not sure how to get it any smoother. Im not using the rev limit map just the fuel map like you said. I adding fuel at 6450 and up.

 

Oh, i missed the part about you having a test pipe. But I would def look into a cutout or catback. It should help raise the curve on the entire top end.

 

yeah im going to try to get a cat back and udp next week to try to re dyno.
I got to get that rev cut better too have you had time to work with yours? i got to finish wiring my new alarm in and im going out to try to work on mine a little. Have you tryed the way danny told you? Thats the way I have mine set now.

 

Messed with it a lil bit today, will mess with it more tonight. I did most of the air fuel, except past 6400. Timing finetuning is next.

 

have you did the knock sensor yet. I set mine to 15.00khz and it reads fine. I would say on timing you could go 10 to 11 across the board and not get any knock. I get my highest knock at 7000 witch is 26

 

I have yet to connect the knock sensor. I will try it out and see how it works for me. Can you hear any of the knocking when the EU sees it?

 

well the highest level ive seen is 26 to 30. Ive been told by some that anything below 100 is not audioable to the ears.

 

well i added a full greddy cat back today. Im not sure if I gained any power. What kind of gain should I expect to see on a a dyno?

 

hey 93turbogxe
i put down about the same numbers on my dek in my 5th gen. my first past was 181 hp and 180 tq and after tuning with a vafc i made 196hp 194 tq with a 13.5 afr. i have the GAB, with ypipe and hks cat back. that was on 17" wheels and on a day where the temp was almost 90 and straight onto the dyno from the highway drive down there. i wish i was able to rev as high as you but i will some day.

 

Hey thanks for the reply but im also running about 11 degrees more timing over stock. By the way what is GAB?

 

ghetto air box mod there's a how to in the 5th gen forum
