My First DSMLink Log

[95AWD6Bolt]

Just looking for some help with Dsmlink. I have a 98 gsx, my mods are in my profiile but for shot I have:

evo316g
pte 880
walbro 255
FPR
AEM Wideband

Attached are two logs that I just did in DSMLink. The only things that I have changed are my Injector deadtime which is set to 420 and global fuel settings to -45% as per the dsmlink wiki.

I am not really very sure where to go from here. The car is idling around 1100-1300 rpms pretty steadily with the a/f ratio between 14.6 and 16.0. When the rpms drop below 1100 the a/f jumps up to 16.2+.
Is that OK?

This is only a log at idle and a few revs here and there. I just want to make sure that everything is set before I start driving around.

AM I good to drive it a little?

Any assistance is much appreciated.

I can't help with the DSMlink questions, but 16 AFR is lean. Stock cars run 14.7 at idle and cruise. I'd read the DSMlink forum for a while until you learn more about what you're doing.

16ish at lower engine speeds is most likely caused by an exhaust leak before the wideband. It doesn't look like you've had DSMLink installed for very long though, because your LTFT Mid hasn't been updated. You should drive it around more and make sure it's dialed in correctly.

Make sure to wire in your wideband and log that. The how-to is in the DSMLink wiki.

Then set your knock light (ECU-->Dash) to light up at 2* and go make some pulls. If you see your CEL flash on then let off and review what happened.

ok, ill check for an exhaust leak.

Yea I havent had it that long, im still learning.

Is my timing high on there? It looks it to me but im not sure.

I think dave and the others have pretty much summed it up. You just need more seat time dialing in the fuel trims before going doing any other tuning. fuel trim tuning always involves a couple days effort just to get things to stabilize when you do it for the first couple times, so don't worry if you don't get immediate results.

check this out, I really like this guide from the link members:

You should be posting this up on the DSMLink forums.

He did, but an extra set of opinions never hurt.

Sorry man, just thought you might of had a DSMLink knockoff. I kinda have an attitude toward those guys, .

Yea its on here the link forums and dsmtalk. I just wanted as many opinions as I can get.

Just a little update, I fixed two vacuum leaks tonight. Im idling alot better now, around 850-900. My front o2 reading is still nuts. It varies from .90 to .04. Something still isnt right. Im gonna check to see if the throttle body is stuck open at all. When the front o2 reads around .90, my wideband is perfect at 14.7

I moved around my 50hz slider and got my stft's to get to 0 when the front o2 was at .90

Do you think i should be messing more with the global fuel sliders than the air?

Im just going by what was said on this site:
baseinjectordata [ECMTuning - wiki]

also, does anyone know where the guide is to wire aem wideband into dsmlink?

 

[95AWD6Bolt]

Took the car around the block last night and it seemed to respond a lot better now that the two vacuum leaks are fixed and with the 50hz slider at -10. Although at idle I still have -10i§h ltft. I'm going to play with it again on fri night.

As for the jeffgst website. Is the timing table on his site according to actual boost or boostest?

When you find that white wire, then locate the wire from your ECU for your secondary O2 sensor. Cut that wire, and then solder the white wire to the wire of the secondary O2 sensor from the ECU.

So:

White Wire--> O2 sensor Wire--> Ecu

Let the other end of the O2 sensor wire hang.

In DSMlink you can choose where the WB is being logged through (2nd O2 sensor you choose this one) And thats it.

Good question and a difficult answer.

The ECU only can guess at what actual boost is since it uses a MAF instead of speed density MAP sensor. If the MAF is not calibrated correctly, the ECU is receiving an incorrect airflow value.

So the answer is : BoostEst

This is why it is so important to calibrate your MAF so that all other ECU functions are calculated correctly.
