DSMLink logs(caution: slow child tuning)

[LandoAWD]

Alright guys, seeing if anyone has suggestions for tuning the Talon back to its EPROM-glory. I've not been WOT in about a week or so, and I feel my man parts shriveling.

Two logs attached. One is easily identifiable as a short jog down the road, hte other is an idle log (has default Link naming convention)

Push me in the right direction.

I have to ask, why is your 50hz slider at +55? That would be throwing your fuel trims waayyyy off. Will it even idle if it's zero'd out? Can you get an idle log with STFT captured as well. Also your coolant temps need to be at 180* for it to go into learn mode, otherwise your fue ltrims will not change.

Here's what ya need to do, go to captured values, add STFT, make sure your fuel pressure is right, get your car up to temp, then start logging, rev it up so MAFraw is at 50hz and try to hold it around there for a little while, that way we can see what your fuel trims are duing at that point.

I'm sure there is other stuff I'm missing, just tryin to get the base down first.

You're getting a bunch of phantom knock. Go to Ecu/Logfile > Knock and change the "And tps above" value to 50 or so. That will stop the knock from showing up.

According to the dsmlink wiki, the global for pte 1000's should be -51, to -55. Your airflowperrev is low - it should be at .28. Make sure your settings are correct on the maf-t.

You also need to log stft to dial in your airflow sliders. Next time make sure your car is up to temp before taking the idle log. Your coolant temps get pretty high in the cruise log so you'll want to try to lower them. If they get too high the ecu will pull timing and hurt performance.

Go to Display > Values, single click on BoostEst in the list on the right, click Props, and enter your altitude in.

Follow this guide to do your maf calibration. Also, check out this thread for tuning advice. I would also recommend getting a map sensor and wideband.

Car won't idle with the 50hz slider anywhere near zero. Tuning to g/rev...slider would be much higher.

AEM UEGO is in (mod list in profile...of course) but haven't tapped the white wire to an ECU input.

Fuel pressure is 37 (hose off)

MAFT is set for 450s.

I'll make sure to get the STFT logged...but I swear I added that to the captured values...odd.

Edit: I'll set Boostest.

[LandoAWD]

Sitting here at work, I'm thinking that I need to check the AUX MAFT knob when I get a sec...

I may be punching myself in the babymaker if I find what I think I'm gonna find.

[gsxtasy]

Hmm, that seems really odd to me. However, I'm not familiar with tuning a maf-t setup, so i can't say for sure. What does your wideband read at idle?

Edit: Whats the AUX MAFT knob do, if you don't mind me asking? I've never played with a maft before.

Cycles around 14.7

The AUX knob might be alright...I had a dumb moment, but I'm almost positive I'm at AUX0/Base2 on the MAFT.

On my brothers car he was having a problem with the airflowperrev being too high (.32). What we did was raise the deadtime 130 over the recommended settings and that allowed us to lower the 50hz slider. Maybe the opposite will work for you. At least it's something to try if fixing the global and/or maft settings doesn't work for you. Oh, and I assume no boost leaks?

[LandoAWD]

This car pulled like a raped ape before swapping the custom chip burn to Link. I ASSume no boost leaks...high degree of confidence.

Valve cover is running a breather, BTW.

[gsxtasy]

My airflowperrev is right around .32 as well. However, I have my fuel trims within +-1% on both, so I don't worry about it. Which takes some tinkering with 1600's, let me tell ya. If you can get your trims close, I wouldn't worry about the airflowperrev too much.

[LandoAWD]

Note, I was supplied with a MAFT manual (and have referred to the same manual online) for a v.2 MAFT. Cracked the box (again) in the parking lot...

....drumroll...

...v.1x stamped on the board.

#### me.

[1992awdlaser]

switch 1=off for 3" maf(on for 3.5" maf)
switch2=off
switch 3=off
switch4=off

base=0
aux=0

MAFT instructions, version 1.3 OLD VERSION - Full Throttle Speed Tech Support

I think we found your problem.

[LandoAWD]

Yup, I was just over on Fullthrottlespeed's site and turned that up. This could explain a LOT. FP was way low when I plugged up the gauge, chip "contents" were unknown for the most part, a few MAFT adjustments for the chip were odd.


If ya want, since you are replying on CDSM too, we can keep the main discussion here and you can ignore the CDSM postings.

I will do that. It's a pain on cdsm anyway because I don't get email notifications for some reason even though I have it set in my account settings.

[LandoAWD]

10-4

checked the admin panel on CDSM and your acct looks fine. Dunno why you are having that issue.

[1992awdlaser]

Oh Kris, just want to remind you not to forget to zero out the 50hz slider after you make the changes to the maft.

[LandoAWD]

10-4 again.

[gsxtasy]

I knew somethin was fishy with that pesky 50hz slider.

[LandoAWD]

2 more logs...idle...hot (may be time for a colder tstat co kick the slim fans on sooner)

I brought the 50hz slider down in the second log so you could see what she does at 0

[turbosax2]

Did you change the maft settings? The fuel trims in the first log look good, but the airflowperrev is still way off.
