thinking about dmlink, need advice

I don't think anybody said it was hard but it can be intimdating for a newcomer to tuning.

I don't think anybody said it was hard but it can be intimdating for a newcomer to tuning.

i'm not a newcomer to tuning, i have just been having things not come together. things like weird fuel trims and i got a dsmchip stage 3 for my 750cc injectors, and i run at 89% injector duty cycle on my 14b at 21-25psi(boost creep, cant always tell) at about 5500rpms the car hits like a wall because toomuch fuel is being thrown in. so i have not had the best experience with tuning my car, but when i read about other people tuning and explaining what they have done, i understand most if not all of it. i took a look at the dsmlink webpage and it looks very easy and user friendly as you have all stated. the only thing that worries me now is the maft setup, i would like others that have used dsmlink with the maft setup to just give me the lowdown on how hard of a time they had with it please. i am not hesitant to buy dsmlink because of the lack of knowledge on it, i just dont want to have another tuning variable added to the one i cant figure out fully, you know what i mean? dsmlink sounds very nice with the wideband, i think this combo is unbeatable from the looks of it. just set the air/fuel ratio throughout the rev band and then run as much boost and timing as possible without or with little knock.

If you run draw thru on your MAFt then you do not need to calibrate your settings.

This isn't completely true. I had to adjust the airflow sliders on the low end to get my car to idle descently and stop bogging down so badly on the bottom end till id hit about 3000 rpms. I moved the airflow sliders around using the STFT to judge if i was heading in the right direction or not.

It wasn't all that difficult. It took maybe 10 minutes total to get it dailed in pretty close. It honestly looked alot more difficult than it turned out to be. More of the fact that i had only been using the maf-t for adjustments and i never had to think about the airflow like that before. But once it got explained to me how to go about it then it was rather user friendly.

I base my comment off of personal experience. I ran draw through and did not have to do anything. W/ a stock longblock, i as looking at .27g/rev at idle. However in blow thru, I had to do exactly what you said you had to do.

So to understand better my setup is basically stock if its not to much trouble just check it out on my profile. I sold my afc/vpc setup to buy a dsmlink and I will be using a 2gmaf in my 1g. What kind of tuning will I need to do just to have the car running at optimal performance? I dont want any knock and good timing? When I get it I will run a base log and if I see knock how can I fix that, isnt that my timing that either needs to be advanced or retarded? Sorry for these newbie questions im just not real familiar with tuning at all but I really would like to learn.

switch the MAS setting to 2g MAS(on link), and basically you should be fine. you shouldnt knock at all, you dont have anything really that would cause knock, except for maybe the boost controller? In that case i would just turn the boost down a bit.

 

[Xplicit93AWD]

Ok well right now on my 14b im running 17-18lbs. Do you think those numbers will cause knock?

 

[chicagoboostin]

there is a possability it will. if it does... id add fuel, as see if that helps at all w/ the knock. get some 510 injectors man ive seen some in the classifieds for pretty cheap. as for advancing timing or tarding it. ill let someone who knows about that crap chime in.

I didn't even notice that you said draw through so i can't say if it is or isn't true as i've never run mine that way.

Not if you get a decent fmic and/water injection. You'll do probably fine with one or t puls. but as soon as you play with it consistantly, you'll heat soak your stock side mount. I'd only go to 15 psi and lean her out a bit and advance the timing instead of running all that boost. You'll net the same returns. With that boost, you'll just prematurely wear out a perfectly good 14b that will give you a decent return on ebay once you decide to go to a bigger turbo.

 

[Xplicit93AWD]

Well I have a pretty good fmic w/ 2.5" piping so it wont heak soak thats why im running such high boost and i have the fuel mods to back me up also so I wont run lean the only thing I was worried about was since im running so rich with my (255hp fuel pump) and no afpr. How can I compensate for this until my fpr comes in the mail ?

 

[90blacktsiawd]

You can't.

 

[Xplicit93AWD]

You can't.

Ok so since im running so rich will the car be able to drive and idle "ok" until I do get it its running "ok" with the afc/vpc setup

OK perfect thats what I get now horrible gas mileage but it will be fixed soon enough so thanks everyone for you help

Stock 1g's have a pretty aggressive timing map. IF you knock the better fix seems to be take a few degrees of timing out or turn the boost down. I'm guessing stock compression ratio so you should be good to go.

DSMlink customer support is by far the BEST I have ever seen.

AEM's aren't that hard

Well you have it about right but there are much better things about dsmlink then just setting the fuel and making a pull. There are a lot of DSMer's out there with the link and that all get to share there logs with everyone and get help with what they may be doing wrong or just a fine tuning on there setups. I would get a DSMlink if I were you I think its about the best mod I got other then my GT-14 turbo from SBR.

If you have any more ?'s about the link please ask I will do the best I can to help I have had my link for 3yrs now and love it.
