dsmlink with gm maf

[DSM90AWD]

One of these features is the ability to translate GM MAF so you wouldn't need a translator. They do not know when this new update will be released, though.

I saw someone else had posted that (can't find it now). Was this on the wish list or a scheduled upgrade TBA?

I've always thought it kinda silly paying for the Translator and not use any of it's tuning functionality (when using DSM Link, DSMChips..etc)

i followed these directions for tuning my car. wow, what a difference. this hopefully will help you guys understand what i mean when you want your map sensor to match your boostest "boost estimate"

I'm lost as hell right now.. I was under the assumtion I could hook up DSMLink and set my MAFT blow-thru to 450cc, 0-0-0-0, log a run and add fuel where needed till it's tuned..

So what this post is saying is, you can do two things.. change fuel in DSMlink and a wideband (to get an accurate reading of fuel), or change air in DSMlink and a MAP sensor (to get accurate reading of air).

this post just confused the CRAP out of me.

Could somebody please pm me a website where to buy this gm 3.3 bar sensor. I'm in the process of calibrating my maft as we speak and i need this sensor.
Thanks-Nick

1. Turbo Pressure Sensor .. part# 9373269 .. price $51
2. Sensor Connector .. part# 88987997.. price $17

from www.gmpartsdirect.com

BTW for tunning 1G with Link and GMAFT the wideband is more usefull then MAP sensor. But it is usefull to log the boost pressure

i read through the better way for the second gens, and i think it is very easy and understandable, i think the 3-bar map is the way for me. can i use a 3-bar map or does it have to be a 3.3-bar map sensor?
thanks for the help

edit:
by the way, on a 2g if the fuel trim goes over zero to lets say 2, does that mean they are on the rich side or lean side? and when they say they add air, they mean they are making it read more air, thus run richer at that point right or do i have it reversed?

You can use a 3 bar. The 3.3 will just allow you to log .3bar more of boost. which is about 4.4 psi more.
In other words a 3 bar can log right at about 29psi and a 3.3bar is good for about 33.4 psi.
I prefer the aem map sensors. They seem to be more acurate and a 3.5bar is good for 36psi.

In either case you will need to zero out the MAFT/set for stock injecotrs if using the DSMLink (all corrections will be done in DSM Link). Using either the WB02 / MAP Sensor is only to help calibrate the MAFT (e.g. the airflow the MAF is reading vs actual) via the DSM Link.

This is not mandatory as you can do this tuning without either. It will just be MUCH EASIER/FASTER with one of these aids to provide feedback

you dont absolutely need a map sensor or wideband. but it is a must have if you want your car to run properly. you can still tune it, but you will be tuning in the dark without those two vital sensors. i dont think dsmlink people will make a new chip if you sell it. but ## a 1g, you can make settings to your ecu and it saves to the eprom.

I got a great tune w/ DSMLink and not using my wideband or a map sensor... My airflow readings were not accurate but the engine ran great and i got a good tune with it. Thre's enough control on DSMLink to get a good tune without such calibration tools. BUT, the calibbration tools are absolutely neccesary to log an accurate series of numbers. For the sake of accuracy, this is quite important in testing and experimenting.

I am not saying that tuning w/ DSMLink and no wideband is just as good. I'm not talking about tuning for maximum performance. Of course, this discussion is about the use of the wideband or map sensor to calibrate mafs. It is quite possible and undifficult to effectively tune w/out calibrating your modified/non-stock maf. The DSMLink MAF calibration guide does not even call for the use of a map sensor or wideband when dialing in the maf for closed loop operation. This means that w/out either of these, you car will idle fine and operate in light throttle like from the factory (for the most part).

EDIT: I'm a slow typer . DSM90AWD already covered my point. . .

The last two posts covered it pretty good. you can get dsmlink and put the maft to 450cc injectors, and tune just with dsmlink. you can get the car to run good and not have problems. the real problem is with the maft its self. the maft does not convert the signal from the gm maf sensor to the exact signal you would have with a stock maf sensor. it is close, but not exact, your ecu will think you are getting more or less air than you really are, at different throtle levels.

I thought the maft was right on when i first got it, i was wondering why i had to change dsmlink to bigger injectors than i really had, so i would not be so rich all of the time. it was because the maft had to be calibrated. once i calibrated it, it made all the difference. getting a gm 3bar map sensor made it real easy to do.

It really depends on how much hp you want to make. because in my opinion, if you are not going for balls out hp, I would use a 2g maf sensor, then you have no hassle of calibrating the maft. you can just install dsmlink and drive & tune.

You could sell your maft and cover some of the cost of dsmlink. then later if the next version of dsmlink has the option to use a gm maf sensor, then you could throw in the gm sensor, and pay 50 for the dsm link upgrade.

and to answere your question about selling your dsmlink, yes, you can get alsmost what you paid for it back out of it. dsm link will transfer the warranty, and the forums to the new buyer. i know 3 people who have sold there dsmlink for only 50 less than they bought it for. hope this helps you some, i don't know if i explained it that good.

you did explain it very well, thanks man. i was actually thinking about the 2g maf thing that you suggested because once dsmlink comes out with the maf feature, maft's are going to be worth nothing. but this is all a pretty big jump, selling my maft and all in hopes that they will release it on dsmlink... i am just not sure. ... i just asked my brother what he thinks i should do what you suggested because he too hates the hassle the maft creates... do you really think that dsmlink will come out with a maf hookup? talondsp1, thanks man, i was thinking of doing the same thing but i liked the maft for flow, but in reality i might never use its full potential. what do you guys think of the 2g maf, i heard it flows up to 50lbs?
thanks for the help

 

[97gstnick]

the next release of dsmlink is unknown, it is even unknown to the creators of it. they claim somewhere possibly in a few months... but if your going to run the maft now, your going to want the gm map. trust me man, these guys are correct in saying that it is not completely neccessary but you will be happy you bought it. i tune my car so much better with it. i have a much better idea of whats going on instead of tuning with no idea of how much airflow truely is going through.

 

[talondsp1]

but if your going to run the maft now, your going to want the gm map. trust me man, .

97gstnick is right, if you do decide to keep the maft on the car when you get dsm link, you should really get the map sensor. it is a 60 bucks well spent. You will be able to calibrate the maft a lot easier, and you will have your correct boost in all your logs, so you can see if it spikes or falls off at different rpms, and if your boost gauge is acurate etc.

 

[91-gsx]

ya i would get the map sensor but i thought about just selling the maft setup and get a 2g mas. you know what is kinds funny. i have a 2g intake from when i first bought my car and did not know much about dsm's. so i have that already. and i also bought the ebay 2g kit that some of you might heard about. and the flange is for a 1g bov to a 2g mas... somehow everything adds up, maybe it was destiny... anyway, what do you guys think of this idea, i heard that the 2g mas flows and reads to 50lbs of air. if this is true i might not max it out yet, especially on my 14b. 50lbs is also big enough for 50 trims, and this is without hacking, not sure about the hacking though. could i compensate for a hacked 2g mas easily?
thanks for the help guys

compensate for a hacked maf in dsmlink? oh heck yes you can. you can use the same method as the maft calibration. you can also switch over to the map sensor if you ever overrun your 2g maf. but that there is a little more complicated and takes good tuning on your part.

i am currently trying to find a 2g mas and the plug, but our classifieds are down.... any recomendations other then ebay?
thanks

um yea, i have one. i would like to sell it.

 

[400HP1GT]

Mitsubishigraveyard.com I bought the 2G sensor and plug for $65.00 in june of 05. I have been told that a 2G sensor will flow enough air for a EVO 16. I have had no problems at all with my set up. Select 2G sensor, set air sliders to 0 across the board. and go tuning. You can view the operators manual and set ups on DSMLINK.com homepage. Go to downloads link and download manual. good luck.

hey guys, i just wanted to tell you that i went ahead and bought a 2g mas along with..............
dsmlink. you guys, i can already feel the power
later

I would like to know this also so I can try and get something from a local store around here. I've waited 3 weeks to get DSMLink up and running and now realise I need something else.. I dont feel like waiting another week.

Side note: why does GM Direct charge me shipping seperately? wtf.

check on dsmlink forums. they have the parts numbers for the sensor
