DSMLink V3?

[thekellbeast]

I'm going to be getting Link for my Talon, and I already have a socketed 95 ecu, and a Palm IIIc on order. All I need to do now is order DSMLink, but I don't want to order it and then have to order V3 when it comes out. Does anyone have a solid release date for V3? I can't find anything on the DSMLink website, and the last rumors I heard had it coming out in Jan of 06, which has come and gone. I don't want to sound really impatient, but it's basically coming down to me ordering it this month or next.

I'm not a member of the DSMLink forum because I obviously don't have it yet. If anyone has any inside info that they can share, it would be much appreciated. Thanks.

Its still in the process of being built. I emailed Thomas about it before i got it and this is his reply


No firm idea on release date, now. We're just now starting on the
design phase if that tells you anything. I'm *hoping* we'll have
something in 3-4 months. We better have or else I'll be getting pretty
annoyed about then.

Upgrades will, of course, be available at that time. We certainly won't
require anyone to buy a whole new package.

If "I" had to guess Id say it will be a few more months yet. And even so, You can always upgrade later

####it then, I'll just buy V2 next paycheck. Thanks for the quick reply.

 

[DevilSperm]

Yeah thats what i said. Just buy it and learn it. Though the next version sounds like its a complete rebuild, but the tuning you will learn will carry over. No problem

Anyone know what V.3 is going to add? I might become interested if it'll allow a conversion to speed density.

 

[Baron4406]

My GUESS (and its just that a guess) is that they took notice to the speed density mode available on the new MAF Translator, and may be incorporating that. I also assume they will integrate GM MAF capabilities out of the box (no translator needed)

Ive heard that too. Also offline editing is planned as well. I like that

Does anyone have a guess as to how much the upgade to v3 will cost if one already has v2? How much did the last upgrade cost to previous users?

I'm also interested in that. And now to sound like a noob but what is speed density exactly?

 

[dsm-onster]

Speed density is the use of a manifold absolute pressure sensor, intake air temp sensor, and predetermined volumetric efficiency maps to determine airflow into the engine instead of directly measuring the airflow via a MAF.

The one thing in the works I'm interested in, for the 2G, is the knock reset on clutch activation similar to the 1G version...I get intermitten knock between shifts, generally 3rd-4th, and if it does knock I get some nasty retard at the begining of 4th that kills me. I haven't been able to get a handle on it and this is a fix for that.

 

[rjdavis21]

interested in this also and how much the upgrade will run?

 

[Lunch_Box]

I believe it was like $50 to upgrade from V1 to V2.

 

[rjdavis21]

sweet not bad at all

yup, its gonna be sick. V3 alone will make me buy another DSM, i cant deal with these hupty mustang dyno retards that dont know anything about tuning out knock. they think when timing goes up is a bad thing, and always more fuel=more power. idiots. wish i knew what i was doing so i could modify dsmlink to work in a stang, and teach diablo/sct how to really tune.

 

[exile]

problem 1 is you're tuning a stang. =)

Here is a break down of the possible upgrades for V 3.

Major enhancements thread, part 2

--------------------------------------------------------------------------------

The following summarizes many of the suggestions presented in this thread as well as roughly where we stand on them. These are items under consideration for the next major upgrade release of DSMLink (both 1G and 2G).

2G ONLY - ALREADY PRESENT ON 1G
Memory board
Static timing adjustment while nitrous is activated. Also increase the upper limit on the RPM window.
Clear knock on clutch input
Option to lock in open loop so as to free up FrontO2 input for other things
Injector disable
SERIOUS CONSIDERATION
GM MAF direct interface to ECU
Closed loop wideband functions
Additional solenoid controls. Probably define sets of parameters and have each output controllable by any "type" of parameter set.
Security code before startup
Input smoothing in the ECU for all custom inputs, including possibly the RPM signal.
Overboost timing adjustments; perhaps coolant temp based adjustments as well.
Extended RPM and airflow ranges on fuel and timing maps.
Direct access to large parts of the fuel/timing map. Accessing all of both maps may be prohibitive, but we'll try.
Full time speed density option
"2-stage" knock retard light
INVESTIGATE AND CONSIDER
Boost control
Fuel/timing adjustments based on amount of time on full throttle (really what people need that talk about load or gear based tuning)
Control over knock retard logic
Coil dwell time control

Keep in mind that I probably should not have posted this but I thought since everyone was curious about it I did. I just hope it doesn't get me in trouble over there. Also keep in mind that some of these will not be in the next version.

Thanks for posting this, hope you don't get in trouble.

Speed density on the we'll try list, I'll be sticking to my eprom.

 

[rjdavis21]

the security code startup sounds cool..but would you need the computer in the car to enter the code? or will it be through some part of the car?? how will that work exactly?

 

[tstkl]

I say make it so that anyone with the wrong dna that comes within 100 feet of the car is shot on sight, but thats just me....

I'm really not sure about your knowledge base, however from all experiences I've had, Speed Density is more of a "popular" item than an actual benefit. Its not any more accurate than a 3" or 3.5" GM MAF, and if you're going on the "less restriction in the intake" theory, The MAF is such a practically non-existant restriction it really is essentially nothing. As far as theory goes, it is a "better" way to meter air, however to convert from a MAF system to a speed density system just doesn't seem to be all that beneficial. Sure there are benefits like not running rich when you have a boost leak, and being able to blow off rather than recirculate, but those are extremely minor to me personally. however you also have problems like having to retune the car depending on the weather/temperature.

I just think if thats the only thing holding you from buying DSMlink, and i haven't blatantly forgotten some major benefit, then maybe you should look into it more.

On the old TMO chips you would hold the clutch in after watching for a particular signal flashed from the CEL. I would guess it would be the same typwe of thing for DSMLink. I personally found it annoying, but if I went to an area that I didn't really want to take a chance with my car I would turn it on.

Well. I agree w/ you generally. but remember that any decent speed density setup will have a tmp sensor. So temp changes in the atmosphere are thrown in the speed density calculation.

But every single time you change the VE (flow) of the engine (upgraded cams, different turbine housing or turbine wheel, bigger exhaust, upgraded intake mani, head work, stroke, bore), you ahve to retune to get her dialed in correctly. All upgrades that increase VE would cause your original speed density tune to go lean .

The GM MAF in blowthru seriously increased my spoolup... So yea, it's not a restriction, any more than in intake valve . Blow through will let you run w/out intercooler piping if it blows off. I run a BOV to the atmosphere and as long as my boost leak isn't in my throttlebody or intake mani then a boost leak is not as much of an issue WRT the fuel tune.

Air is air.

Speed density has many benefits. The GM MAF's offer far less restriction than the stock maf sensor, but they still are a restriction, I've heard reports of stock camaro's and transams gaining horsepower with a switch to freer flowing aftermarket maf. Also load based maps, ability to log boost pressure and intake temp, I know you can do this with out speed density but its alot more work in comparison, considering its already done with speed density. Its well know that you can no longer trust the logged airflow values of the maft setup's especially when in blow thru, so accurate airflow numbers is another benifit.I can already do everything else I would ever want to do with my eprom, having to retune the VE is no big deal unless you are constantly changing parts. Another thing to think about, how many race engines do you see with maf sensor's? I can't think of many if any, there's got to be a reason for this.

so this could explain my fuel cut. hell once I get dsm link I think I might switch to an evo 8 maf just for the simplicity of it all. or speed density for the complexity of it all
