ECMlink dsmlink log,only 309whp?

[mitsuclipsegsx]

went to dyno and only got 309whp,pretty bad for my mods,does the log look good?/

thanks

Im not a dsmtalk member but I can say something is wrong. Looked at you mod list and you should be hitting over 350whp.

How does the car run? Any stuttering, knocking, etc?

Boost leak test the car and run a compression test. You may find your problem there.

 

[mitsuclipsegsx]

ok this file should work, no knock, runs great, yea i am gonna do a compression test to see whats the problem.

Your log looks similar to mine, well at least the settings of fuel/timing. All my mods arein my profile. The estimated hp figures I get are similar to what your log shows. So I actually feel good knowing my car SHOULD be over 300WHP mark. You definitely should be up to 350AWHP as you do have cams. Your airflow numbers look low for that type of turbo. I get up to 40lbs/min with my 50 trim on stock cams at low 20 psi of boost.

 

[mitsuclipsegsx]

So what should i do for the airflow,shit now i am afraid to do a compression test.

The last thing you should worry about is the dyno numbers. Every dyno reads different. Just go to the track and see what the car traps. That will tell you aproximately how much power you are making.

I'd say you should try to add more timing. I am flowing 37 lbs/min on a 50 trim at 19 psi (But my compression is in the 140 range so i'm not surprised) with stock longblock including cams and intake manifold and i am running 14 degrees peak timing. I wish i could get more but the bi*** will knock just past 6k at anything above that. My next step is to throw race gas in it and turn the boost up.

What are your air/fuels looking like? I'm in the 11.0 range across the board according to my plx wideband.

 

[scottsee]

You have Alot more power left in that turbo! Boostest show 18-19psi is that correct? You're only flowing 35lb/min. Thats 16g airflow! Shit, on my old 14b I was hitting 300tq/290hp est on my meth injection at 32lb/min airflow.. Why did you ajust your timing sliders so low? You're only getting 11deg advance, thats ####ing you up huge! You also are running heavy on the rich side. You have a lot of tuning to do..

 

[andymoraitis]

You're only getting 11deg advance

That's also pretty damn dangerous on stock internals. I wouldn't recommend anything less than 14 degrees peak timing on cast parts. At least get the timing up to 14-16 peak advance, straighten out the A/F to 11:1 or so on pump and then see what she'll tolerate on boost.

Scott is right. You need to get some wideband data in there and up that timing. With your mods at 20 psi you should be seeing more airflow than that

 

[scottsee]

Would you post a log of zeroed out Timing sliders and fuel estimation at 10.5:1. There is over 50-80tq/hp hinding in there...

 

[mitsuclipsegsx]

shit i have a lot of work to do, i went to victor reasearch for the dyno and tune, those assholes.

Are you saying i am running 18-19 i know link shows that,but my autometer gauage and e-01 stays at 20psi to redline,ok can someone just tell me what number to be into link, that would be great

thanks

I'm not sure what you mean by that. DSMLink's boost estimate is "notoriously off", as it is an estimate. It's usually not dead on, and is only dead on with your boost if you adjust your airflow sliders. Trust your boost controller or gauge.

And how did the dyno session go? (I'm guessing not good)

Did you get a log from it?

 

[scottsee]

Boostest is only accurate around 5500 rpm. You can calibrated your MAF via the Airlow sliders by comparing my 3.3bar with Boostest with dsmlink at diffrent MAF hz .

Example: At 5500 rpm your 3.3bar shows 19psi and Boostest shows 17.6psi you caculate the offset by the following equation.

(14.7 + 19.0) / (14.7 + 17.6) = 1.04 - 1 =0.04 or about 4%

Once you get the percentage you need to cross refrence that with the MAF hz to make the approprate changes to your airflow sliders.. It's pretty common for people with uncalibrated MAF's to show higer then actuall airflow reading from their turbo. Hope that helps...

 

[mitsuclipsegsx]

the log from the dyno is the one above, so can anyone tells me what numbers to put into link to make it better?

 

[slipstream808]

The log from post number 4?

 

[mitsuclipsegsx]

yes.

Well, in my previous post I asked you to zero out your timing and shoot for 2g/est of 10.5 on your fuel sliders and re-post....

 

[mitsuclipsegsx]

here you go.

 

[olmytsi]

You could start by adding fuel where it's knocking and see if it goes away. If not, put the fuel back where it was and start taking timing out and see if that helps.

 

[slipstream808]

What's with that dip at 5300 RPM's?

Add some fuel at 5500 RPM's. Do a 1% increment up. If that doesn't work, add at 1% at 5000. If that doesn't help, add another 1% at 5500, then at 5000. Then add 1% at 4500. Remember, try and PREVENT knock.

 

[mitsuclipsegsx]

The 2nd one I adding more fuel in the upper rpms to get rid of the little knock i had,how does it look, and what should i do about my airflow?

thanks

 

[1g4my2g]

The advice so far is good, however the readings may be off. Do you have a fresh knock sensor? I have seen people go crazy because the sensor was old and the readings were not correct. Remember the DSM Link uses all the factory sensors, "aside from the wideband of course", but if everything looks good IATs Coolant, boost etc and you're still not getting what you want, check the sensors! I know this may be a beginer thing but many many tuners forget this. Hope this helps. Good luck Oh and your logs look good, but I'd add Coolant on the graph as well as the wideband. Knock count looks great.

 

[slipstream808]

Whats wrong with the airflow? What psi are you running at?

At this point I'd say you should invest in a wideband so we can see what your actual AFR's are. Up the boost and see what happens if you want?

And which log is first? 2a or 3?

That does seem to be a lot of fuel to have to add.
