DSMLink tuners

[Laser0385]

Hey everyone,

Just got done doing a bunch of install work on my Talon and need some help with basic tuning via DSMLink. All of my modifications are listed in my profile.

Quick synopsis of what the current issue is: car starts, slowly builds RPM to around 2k, plateaus for a very brief period of time, than stumbles and dies.

I have attached a log for those of you that have DSMLink, perhaps you can assist me.

I noticed the hole log your running Rich....
The last bit your at about 2k and 11:1 - 12:1 As it dropped to 1000Rpm you A/F ratio droped all the way to 9.5:1
What fuel Presure are you running with the 680's?
And Also is your front o2 hooked up?

WAIT do you even have a Wideband??? I don't see on in your profile?

As for the front o2, it is plugged in but I suspect it to be dead. It holds constant at .06 volts.

And no, I do not have a wideband. I am trying to get the car running decently enough at idle and cruising so that I can get the car down to Pina.

Have you posted this on the DSM Link forums? If not, you should.

Yep.

Haven't gotten too much attention over there. I was hoping someone local would have some time and knowledge to spare.

Well, new front oxygen sensor is on the way.

Anybody have some more advice for me?

 

[droppinbottom]

What else did you install at the same time?

Is this the same ecu that you had before link or is this a different one?

The GM MAFT, the FMIC and new spark plugs. Other than that, everything was the same prior to install.

I am about to head out to the garage and use my DSMLink to check the fuel pressure.

Still looking for advice on what to change/fix besides the oxygen sensor to correct this problem.

Boost leak test?
Double check spark plug gaps?
Make sure MAF-T is set up correctly to work with DSMlink?

BLT was good prior to first start up.

Spark plugs were new prior to first start up.

I am PRETTY sure I have the MAF-T set up correctly to work with the DSMLink. Everything is set to zero except for AUX at 2. I have it selected as 1G MAF on the DSMLink.

I did just check the fuel pressure with my DSMLink and the gauge read 45 psi. So it's about 8 psi above stock fuel pressure levels. I recalculated my global setting and deadtime.

Started at: -34% Global / 210 Deadtime / 45 psi fuel pressure
Recalculated at: -46% Global / 315 Deadtime / 45 psi fuel pressure

I will give it a go tomorrow with my dead front oxygen sensor and see how it plays out. I may go in and switch the front oxygen sensor OFF with the DSMLink and see if it will idle. Than, I can switch it back ON once I get the new sensor installed in a few days.

Here are two new logs just taken.

First log is with the dead o2 sensor on and the new global/deadtime settings.

Second log is with the DSMLink turning the o2 sensor off and new global/deadtime settings.

Advice welcome.

take it to english racing they know about the 4G's alot more then pina but its up to you on where u take it too.

4G's?

And I have heard nothing but good things about Andre at PINA. But also great things about English Racing.

4g's = 4G63T's . dsmer talk im just saying i heard the dyno at PINA can mess up your car and someother things. engilsh racing all i said about it is alot of there mechanics sepcialize in the 4G63T's so they know what they are doing.

i also have a 94 laser and a 92 TSI just the turbo is starting to smoke on the tsi. does anyone have a set of 550cc injectors and a 2G mas?

Okay, can anyone else confirm that the dyno at PINA can mess up your car and some other things?

I personally haven't heard any stories, but I have been out of the DSM world for a couple years.

thats the only think i heard. just alot of people like english racings work. Andre has done some great work on dsm's.

First log is with the dead o2 sensor on and the new global/deadtime settings.

Second log is with the DSMLink turning the o2 sensor off and new global/deadtime settings.

I can't open those logs. I'm getting an error. Do you happen to have any others or can get more?

 

[cerberus95tsi]

well if your just looking to get a dyno run in and dont wanna worry about falling off the rack .
go to Z Sport in everett on smith ave they have the dyna pack system

it bolts on instead of your wheels and is way more accurate

Wow, that sucks. Guess they should triple check the tie downs eh?

Weird. I posted them on DSMLink and they couldn't open them either.

I will take some more tonight once I adjust the Global settings and Deadtime yet again.

I need a full tune, not necessarily a dyno. Knowing the hp/torque numbers once it's tuned is fine, but the tune is the most important.

Anyone local able to swing by and help me out with my DSMLink?

The English crew and I are coming up to Pacific Raceway on friday afternoon for BOTI. You should call Luke or Aaron at 360-210-7484 and see if they can help while we are there. My suggestion would be make sure everything is together and all sensors are working correctly so you wont waste their time. Tell them you dont have a wide band so they can use the portable. Jeff

The problem is I need someone a little more experienced with the GM MAFT and DSMLink to make sure I have everything set-up correctly. After that, I need to get a base tune on the car so I can actually drive it.

As of now, it is just sitting in the garage while I try my best to get the idle figured out.

If you can get Luke to stop by he is more than capable of helping diagnose the problem.

As far as that dyno vid posted above, it looks just like the Drift Office dyno area. But either way that can happen at any dyno.
