DSMLink w/ Wideband o2?

[Xtraction]

I just traded (with a co-worker) my 98' GSX ECM & S-AFC for the DSMLink system out of his 98' GSX...SCORE!!! According to DSMLink's site you can get your laptop to read real time A/F by using a wideband o2 sensor fed into the MDP (manifold differetial pressure) sensor. Here's a picture of the MDP below.

DSMLink also assumes that you're going to use a TechEdge wideband unit. Can anyone using the DSMLink and running a wideband set-up tell me how your doing it...please?

What they mean is that the wideband O2 sensor has an output that is fed into your cars ECU to then log data through your DSM-Link. The data that your O2 is now sending is usually fed into your EGR (pin #6), MDP(pin #73), or rear O2(pin #75) input on your ECU.

I would use the rear o2 pin out for your wideband and use the MDP for a 3.5 bar map... Deadly dsmlink combo

My dsmlink is coming as we speak. I already almost have the PLX m250 installed and I will be hooking it up to the rear o2 sensor pinout.

Keep me updated and let me know how it goes. I've got another question. I got my DSMLink (like I said) through trading with a co-worker. How do I get the DSMLink program for my laptop when it comes time to fire it up? On their site it says that the DSMLink is shipped with a program CD. I don't have it and neither does the last owner because he bought the car with the DSMLink already installed. Any ideas?

...and why the hell is my reputation square red? Just curious...I havn't done anything wrong...I think.

In order to get any support from the folks at DSMLink, you're going to have to have the cable/adapter as it is the key to your DSMLink. It is your proof of ownership. I just hope you don't have a pirated copy because if you do you will get no support from DSMLink. I don't know how all this will work out for you if you didn't do a ligitimate transfer through DSMLink. Oh, and if it is a ligitimate copy, make sure you get registered as a user with the folks at DSMLink. Let us all know what happens and good luck!

I've read the entire DSMLink site from top to bottom. I've also tried to send them an e-mail but every time I do I end up getting this bull sh!t.
"The host 'AOL' could not be found. Please verify that you have entered the server name correctly. Account: 'Aol', Server: 'AOL', Protocol: SMTP, Port: 25, Secure(SSL): No, Socket Error: 11001, Error Number: 0x800CCC0D"
I'm not a super computer guy so I have no idea what this means. I don't have AOL. I have Comcast cable internet. I opend the ECM case and this is what it said on the EPROM...
DSMLink - 1353
ID : F67540750
I also know the original owner of the system and both owners between him and I. Proving that it's ligit is not a problem. I have the cable adapter as well...not a problem. All I need to do is get in contact with DSMLink so that they can add me to their users list and get a copy of the program but there's no freakin phone number and I can't get an e-mail through.
F#@K&*G Piece of $H!T computer...
Does anyone know of a way to get ahold of the people with DSMLink other than e-mail cuz that aint working for me. Thanks in advance for any help that you guys can give me. I appreciate it...a lot.

Simplest way? Just grab a GMail account. http://www.gmail.com

It looks like your email software is trying to use AOL's mailservers for outgoing mail. If you want to fix it, you'll need to get Comcast's 'SMTP' server name and address, and configure your email client to point to that, instead of 'AOL'.

Also, the DSMLink software is freely downloadable from the DSMLink site. No registration needed.

Ta-da.

Also, read the install manual... especially how to hook up the clutch wire if you want to use the stutterbox. Not sure if how to install a wideband is listed in there, but there are threads up on the DSMLink forums, along with recommendations of which wires to use for which sensors. Cheers!

Right on man!!! I played around with the downloads. I figured because their site says that you get a program CD with the package that they were just samples. So the Full install, v2.5.2.16 is all I need to download onto my laptop in order for it to work? I need to do some more homework on the anti-lag set up because I do plan on using it. As far as getting onto the DSMLink forums...I can't. I get this when I try to register...
"Sorry, registration has been disabled by the administrator."
...and I can't contact them about it because I can't get an e-mail to go through to them. I don't understand why I can e-mail other people but when I try to send one to DSMLink by going through their contact links it won't work. Oh well...I'll find a way around it. Thanks for your help!

What do you want to ask them? I'll PM them in the DSMlink forum with your question and your email address.

Sweet! I just need to know what information they require from me in order to register and gain access to their forum. I have the original owners name of the DSMLink unit as well as the two after him. I have the ID # off of the EPROM. What ever they need to varify that my unit is one of the real DSMLink systems...I'll give them. I just want access to their forum for information purbosses. I'll PM you with my address. Thanks man!

I run the plx wideband and it works great, like other have said. Cut your rear O2 sensor from the ecu harness and wire in the wideband output (5v) to the ecu. When you get dsmlink up and running they have plxwideband as one of your options to log. Select this and you will be able to log you air/fuel ratio, instead of just a voltage #, which means nothing to most. If you need help wiring it up, there are a bunch of posts on the dsmlink boards on how to do so. As for antilag, I wouldn't use that if I were you. You don't need it for the evoIII turbo & it will destroy your cat if your running one & hurt/damage your turbo as well. It works by adding fuel and advancing timing so much that the fuel actually ignites in the turbine housing instead of inside the combustion chamber. Just think about what this does to your turbine wheel & you might change your mind.

 

[Dark_Horse]

True, for a 16G, you don't need antilag. But for a larger turbo, it's great. And it won't hurt if you only use it sparingly. If you're on it every day, then yes, it will damage your turbo/cat, but once in a while you're fine.

 

[Xtraction]

Ok so maybe I won't use it...at least until I get the FP3065. Thanks for the info.

 

[BenHenthorn]

On the PLX M-250 there are two wires (one for narrow band and one for wide band). Did you guys hook up both wires to the rear O2(pin #75) on the ECU? Did you leave your rear O2 plugged in still?

 

[96whgsx]

I installed only the wideband output signal. I just had another bung welded onto my o2 elim dp. Rear o2 is out in the open and I pluged up that bung. The reason is that my o2 sensor is just about totally stripped so I don't want to risk stripping it more to the point where it can't come off.

 

[Shane2GSX]

I know this thread is a little old but I'm also planning on running DSMLink and the PLX300.

So if I'm understanding things correctly. You hook up the PLX like this.
WB/NB sensor into front O2
NB output goes to whatever pinout is for the front O2
WB goes to the rear O2 pinout

So would the ECU not see that the readings on the Rear O2 are not correct and throw a CEL??

Some of you stated not even hooking up the NB. Isn't this needed?

I am completely confused.. Help!

First off questions about the link should be posted on the link forums. Information you get there will only come from people who use it and people who created it, not 3rd person "I heard from my friend's cousin" which here is likely. Leave your stock front O2 sensor alone, it's doing it's job fine. The wideband sensor will go into your downpipe in front of the cat if you have one and wherever if you don't. Wire the 5v output from the wideband into the rear O2 pin on the ECU. The rear O2 only checks for catalytic converter operation and will not affect the car. You can disable the CEL you will get with DSMlnk's DTC menu. Select the wideband you are using to log and which input it's connected to. Done and done.

I asked it here because many have posted questions about dsmlink on tuners, and it also concerns another product. Besides that, don't you have to have DSMLink first before you get access to the forums?

I would think that you would want the PLX sensor in the front for a more accurate reading. Since the PLX measures both narrowband and wideband, could you not put the sensor in the front and wire the narrowband output to the ecu's front O2 (pin 76) and then wire the wideband to either an open ecu pinout or the rear O2 (pin 75)? This seems like it would give much more accurate readings for wideband.

Wideband sensors are much more sensitive to heat and when running a turbo most manufacturers recommend placing the sensor at least 36 inches downstream of the turbo. Placing it in the front O2 location can severely shorten sensor life. The narrowband functions are simulated from the wideband values. The stock O2 sensor was designed to live in the environment of the O2 housing and there is no reason to remove it. Unless you have an exhaust leak your readings aren't going to vary from the O2 housing all the way to the tip of the exhaust, this is why sniffer widebands like used on dynos can work, they just shove them in the exhaust and clamp it down so it doesn't blow out.

Okay, didn't know that. Good info! Makes sense now. But would this present a problem when dumping an external gate to atmosphere? I'm not sure, but I don't see how it would change the a/f ratio as long as each part of the exhaust is mixed equally.

 

[elfroggo]

I thought it does affect the reading when done at the tailpipe because the wideband is measuring Air Fuel Ratio. In a catalytic converter exhaust sytem, the cat will burn off fuel, changing those values. That is why the wideband sensor should be placed far enough away from heat source (turbo), yet before the cat. Of course if you are running catless then you can use tailpipe.

The exhaust being dumped is the same exhaust as what is still making it through the turbo.

I mentioned this earlier. The tailpipe sniffers are temporary use and should not be considered for a wideband that will permanently installed on a vehicle.
