DSMLink V1; Feeling Choked

[syndr0me]

*ALL ARTICLES I FOUND OR GOOGLE RELATE TO THE NEW V3 OR MOSTLY V2*

Hey guys,

So I finaly got around to getting a 200W power inverter for the laptop to tune DSMLink. I'm using the ECMLink V3 software and run it for the DSMLink V1 config because its the only way it will connect. I am assuming I have V1 at this point.

Now the previous owner said the tune has pretty much been done but ... I rather make sure.

When I go to capture a log, what values should I have listed? Remember, it's V1 my choices are fairly limited. I also noticed it says BoostEST and afrEST. I guess this mean they are estimate and not real values. How to correct this? I know I have an aftermarket o2, because I have a sweep gauge. It's leading me to think I have a narrowband o2 and not the real deal or unless its just a sweep gauge.

My choices of "windows" or "views" I have is

- TPS/RPM (set Launch and TPS tweaks)
- Fuel
- MAF
- DTC/Misc.
- Stream Window

I can't even have direct access.

This really sucks because before I got the car I spent countless hours reading up on V3 and figured at worst the car would come with V2 and it would still be doable. but with V1, man oh boy, I feel so choked and no room to breath.

Thoughts/tips guys !?

Thanks!

IM TRYING TO GET DONE WITH V1 ONLY. NO SUGGESTIONS ABOUT UPGRADING TO V3 INCLUDED BUT NOT LIMITED TO GETTING A BETTER WIDEBAND, MODULES, GAUGES, GADGETS ETC. THE CAR HAS 2 WEEKS LEFT TILL STORAGE SO IM JUST TRYING TO WORK WITH WHAT I HAVE AT THE MOMENT. V3 WILL COME NEXT YEAR, 100% AS WELL HAS EVERYTHING ELSE. SO PLEASE NO V3 UPGRADE SUGGESTIONS

V1?

Are you also using an abacus to calculate fuel adjustments?

I would contact Tom at ECMLink and get some upgrade info and options.

ABACUS, .

Sure thing, ill see what I can do. In the mean time, anything else?

 

[Calan]

Unfortunately, I'm not sure what to tell you. I'm not even sure what the limitations were with the original V1. With at least V2, I could point you in a good direction. It still wouldn't hurt to contact ECMLink though; maybe they could do something super cheap to at least get you on V2.

Maybe someone that remembers V1 can jump in here.

I'm not sure what the overall question is. Your output sounds fairly similar to what a v2 chip will display in the v3 application, maybe a bit more limited. But you'll still be able to tune with what you're given. No, it won't be as good, but you should be able to at least get started. Can you post up a log?

Yes, BoostEst and AFRatioEst are just estimates, not real values.

If your sweep gauge is just that (lights going from left to right), then it's just a gauge hooked up to the front narrowband sensor. If the gauge has any numbers on it, then it's for a wideband sensor.

Pretty sure the V1 program looked something like this:

You must be logged in to view this image or video.

...and, of course, this would be a V1 screenshot:

You must be logged in to view this image or video.

You can clearly see by the log that the user in question has just 8* of timing at 6000rpms. Pretty conservative pump gas tune he has going on there.

I'm just awesome like that, what can I say?

Yes but I notice my OEM O2 sensor is snipped n still in the housing. But in DSMLink I still see the O2 cycling. O2 simulation?

 

[snowborder714]

If it's o2 simulation, then it must be from the o2 controller and not the link software. Do you see another o2 in the exhaust anywhere (not including the factory front and rear, if they're both still there)? Another way you could check is look at pin 76 going into your ECU and see if another wire is spliced into it.

This is odd. I've never heard of a narrowband gauge that simulates it's own signal.

So... where is a V1 ECU getting that O2 signal from?

I only saw a 4/5 (need to double check) plug that leads to a sensor, narrowband I assume, on the Turbo downpipe. so what your saying is that my narrowband hooks up to a controller and has 2 outputs. One to the sweep gauge and the other spliced into PIN 76. Correct?

Oh, shush. That's assuming he has a wideband and doesn't know it.

If your front o2 wires are snipped but you're still getting a signal in link, then I can only assume is that you have a wideband and don't know it. I think you need to do some more investigating and maybe post up some pictures if you're unsure what's going on.

 

[syndr0me]

If your front o2 wires are snipped but you're still getting a signal in link, then I can only assume is that you have a wideband and don't know it.

Ditto. The previous said it had a wideband and I was under the impression I had one to.

The two things that doubt me are the sweep gauge and afrEST in Link.

Is it safe to say I have a wideband because rest assured, my front O2 is snipped, that I can guarantee.

 

[snowborder714]

Look at your exhaust and see if you find another sensor.
Post a picture of your gauge.
Look at pin 76 and see if another wire is spliced in (possible narrowband input from wideband controller, if there is one).

We need more solid info and can't give you answers on assumptions.

 

[syndr0me]

Wait.. are narrowbands just regular O2s? I was under the assumption that it's a an upgraded sensor, like a wideband, but just cheaper and less accurate.

If there are just regular O2s I'm so embarssed.

 

[snowborder714]

Yes. The factory front o2 sensor is a narrowband (outputs 0-1v). A wideband is an aftermarket sensor that is basically a high resolution version of a narrowband (outputs 0-5v).

Yes, a wideband has been beat into my head. In the laptop bag came with the car there was 3 thick printed documents regarding AFR and Wideband functions along with theory and calculations. I just never bothered to look up a narrowband as I assumed it was a middle between "regular O2s" and a wideband and that it wouldn't concern me so why bother reading about em'.

But thanks for the clear up

Ooohhh, I see what you did there

 

[Calan]

Yeah...that's what I was wondering.

 

[syndr0me]

OK now. I'm at work at the moment and have been since the beginning of this thread via cellphone. So pardon me for not taking pics and looking at stuff in detail like you guys said but I won't hold myself in thinking out loud.

RECAP::

I have two sensors in my down pipe.
- A 2 wire which has been snipped.
- A 4/5 wire one about 3 inches above the 2 wire one.

I have a sweep gauge which usually just reads off a narrowband sensor.

An afrEST reading in link.

I mean honestly, I can only see one possible explination. It's a wideband hooked up to a crummy narrowband gauge with a PIN 76 splice allowing me to see an O2 simulation.

I know you said I shouldn't assume but like I said, for now I'm thinking out loud since I'm stuck at work.

Now the real question is how do I get a REAL AFR reading in link?

Inputs anyone?

 

[snowborder714]

The AFRatioEst value in link has nothing to do with your sensor situation. That's just a value that link will always display. That doesn't matter in this discussion.

As for reading the wideband in link, if you do truly have v1, I'm not sure if the software will still allow it. If it does, you'll seen an ECU Inputs tab, which is how you'd configure link to log the wideband.

 

[bastarddsm]

I seem to remember you could tell V1 to read a 0-5v wideband. I never used it but I remember reading about it waaay long ago.

Also when you google it. Set the date back to like 2006 and prior.

Sweet. Never knew I could do that. That is definitly going to help. Thanks broski.

This is going to be a very multi-topic thread. Now that we have talked about afrEST for the most part... BoostEST is still in question. Don't our cars come with MAP sensors? Or were they like my 3800 Series 1 Supercharged GM engine I had where the MAP sensor was purely for the stock boost gauge and was not even linked through the ECU?

 

[snowborder714]

BoostEst is the same as AFRatioEst. It's something link will always display and relies on no sensor. Our cars came with MDP sensors, not MAP sensors. They're not capable of reading boost, and are only good for telling you if your EGR valve is functioning properly or not.

We have no factory way of reading accurate boost. All you have is the shitty factory boost gauge, which again, has no direct sensor tied to it. If you want to read accurate/actual boost, you'll need to purchase and install an actual MAP sensor (GM, Omni, or AEM are the popular ones).

 

[bastarddsm]

Nope no map sensor, theres the MDP but it doesn't measure boost. The BOOSTEST is just a calculated value by the ecu, based on the airflow and the rpm. Its basically there for you see that you have the maf somewhat compensated correctly. If the BOOSTEST is close to your gauge reading your maf is probably calibrated pretty good.

 

[Calan]

If the BOOSTEST is close to your gauge reading at peak VE (5000-5500rpm), your maf is probably calibrated pretty good.

Fixed.

 

[syndr0me]

Well know... I finaly got myself all set up ready to log. I embark on my late night crusade. KAPLOOOW! ! Exhaust snappes a couple of inches after downpipe. Was so loud n scared the #### out of me like intense.

Well luckily I got a bit of info ... from memory. Was planning on getting used to doing small pulls n setting up captured values correctly then Save logs.. but like you guessed, I was not able to get that far.

Things I remember... with my own analysis.

Injec.CC....................... 663CCs
FuelBasePressure..... 43.6PSI
Comes to like 22% adjust (???)

IDLE::

AirflowGrams/Rev ..... 0.26g/rev <----Good
CombinedFT ..............10-12% <---- Not good
ThrottlePos................. 1% <---- Good but should be 0
RPMs......................... 950ish <---- Good, stable and it's what it is set at
CoolantTemp.............. 190F <------- Good
MAF.HZ.......................... Do not Recall <--- Is it important? 35hz maybe from faint picture memory.

OK that is it for Idle, Now here is a modest 2nd gear pull on Pump 94 Oct.

ThrottlePos............. 65%
RPM......................... 4700-4800RPMs
BoostGauge............ 20-22psi
Timing...................... 8*
KnockCount........... 0 (Could of read KnockRetard not sure)
Inj.DutyCycle.......... 57%
CoolantTemp..........196*F
IntakeTemp............. 59*F
AFR .......................... Can't find an option to read widband in V1 :/


Anyways, I know it's not much but now I'm kinda bummed I gotta put money on it for a damn exhaust repair.

Inputs?
