Haha, ok. Patience. Are there any non-nitrous dsmlink cars breaking into the 10s?

Into the ten's? I don't have time to generate a list, but sure. My buddy Brian ran a 10.1 @ 140 on pump gas and a 35r last fall. Self tuned with Link V2 and a GM MAS. The car weighed over 3000 lbs with him in it, and he's never sprayed the engine either.

There's a pretty impressive thread of track times on the Link boards. Maybe I can PM you some of their times if you aren't familiar...?

One of the 10 second or quicker cars (5 so far this year) on the 2009 list used N2o.

In 2008, four of the 10 second or quicker cars (16 of them) used some amount of N2o.

In 2007, three of the 10 second or quicker cars (16 of them) used some amount of N2o.

The list starts over each year.

 

[bling5tatus]

I'm sorry, I know this is going to sound ridiculous... but I meant 9s.

 

[Hal]

If you say so.

Yes, there are cars on the lists that have run 9's without N2o.

Likewise, for the 8 second list entries.

 

[twdorris]

So are there any logs/dyno sheets or videos

I came across this today and remembered this thread. It's in HD too, so all the better I suppose.

Sweet, but the announcer at the end saying "not bad for a four cylinder" = boooooo.

I wonder what the owner of that car would say about his before/after results of speed density.

 

[snowborder714]

I'm just curious why you're so set on people having noticeable results when switching from MAS/MAF to SD. If you just switch over and don't really adjust your tune, I see no real reason as to why there should be a noticeable difference.

My car seems to run a bit better on SD than on my GM MAF in blow thru. But I had a very good tune on the GM MAF and haven't really had any time to play with tuning SD yet.

Has anyone made any real power on V3 yet? I just ordered my V3, and right when I got it, I went to Pinks and a friend of mine is having an apparent problem with it.

As of right now, I am not making anything worth mention, but he is over 700 whp and is having problems with it shutting down, killing power, maybe due to the amount of air flow coming in, from what I understand he is one of the few highest HP cars on V3 yet. Also from what I hear the other guy with very high HP is having a very similar problem.

I am trying to get an idea, because like I said, right now it is not a big concern, but in the future I would like to run a 2.4, HTA 35r, 100% meth. I would like to know if it is in the program, because if that is the case I would like to return it before I continue.

From what I understand there is ALOT of high HP cars on V2, but few on V3 yet.

Who are these High Powered guys???

My car is doing just fine on V3... It just ran 10.43@133 2 weeks ago. Not bad for an AUTO...

I have yet to make the switch to SD. I'm still running the "POS" GM maf with V3 cable. I dont expect more gains out of the switch just a more consistent tune.

Sounds like a mechanical issue with the car and connected with v3. If you just ordered your v3 go on the link forums and read up. You will find there are very little issues and for the issues there was they where fixed. I would say v3 was pretty much a flawless release. I have ran it for a while with no issues.

You mean John Wood? He's definitely having a problem; a couple actually. The first of which was a collapsed flex section in his exhaust causing a serious loss of power. The second being that crazy loss of power after quick shifting. But at this point, I just can't see it being related to V3. If it is, we'll most certainly fix it. I really feel bad for the guy.

Also from what I hear the other guy with very high HP is having a very similar problem.

This one you've got me stumped on. The only other guy that had a problem recently (that John felt might be related to his own) tracked his issue down to a GM MAF installation problem. Is there someone else?

Oh cool. So are there any logs/dyno sheets or videos showing how the speed density was a major improvement over mas?

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

dark red, and dark blue are Sd (jackal) I know its not V3 but it's SD non the less
lighter red and lighter blue are 2g mas + meth using an afc (I know its not the same as switching from something like v3 using hte mas to v3 going SD, but it is an example.)

Both setups tuned to maximum power on pump fuel, knock limited. The big gains up top I attribute to not having timing control with the AFC and for the AFC tune I was simply turning the cam sensor to adjust the whole timing map. I could have tweaked the timing in the stock chip, but at that point, why bother?

It shows switching not only the air metering device, but the tuning tool as well, so it's not really a valid comparison.

A valid comparison would be the same tool using a MAF, followed by the same tool using S/D.

See I understand your point, but I figured it would still count since your still changing from a MAF based tuning system to an SD system. But I made sure to include that in the post that it wasn't the same as switching from V3 with a mas to V3 SD. I can remove it if you like as to not give people a wrong impression.

Well besides the ecu management change, was there any change in engine mods or higher/lower boost? How about your timing?

 

[airmail96]

This is not my dyno graph it is from a member Lowell Foo on the DS-Map forum. The mods stayed the same, according to his post I would assume there were some timing changes made, because he mentions messing the timing when tunning with the SAFC by turning the cas.

You didn't mention if he changed boost. Also, when he was running just an AFC was he advancing timing with the CAS or retarding. I've read advance with 1g was a no-no because they already run way aggressive timing as it is.

 

[airmail96]

Boost was 21psi for the DS-MAP pulls and 18psi with the stock ECU/AFC. 20psi with the AFC ended up pulling timing and power stayed the same, although it made slightly more midrange torque. Injectors are 680's.

I'm going to assume he was advancing the timing with the cas.

 

[97gstnick]

Yea, so more boost on the new speed density setup doesnt make for a good comparison to a lower boost maf setup.

 

[JayRolla]

I would assume he was retarding timing. You never advance timing on a 1g unless you are crazy. Even on e85 I would not advance.

 

[twdorris]

Boost was 21psi for the DS-MAP pulls and 18psi with the stock ECU/AFC.

That alone increases torque by 9%:

(21 + 14.7) / (18 + 14.7) = 1.092 or 9.2%

The increase in torque shown in that dyno plot was from 266 to 292:

292 / 266 = 1.098 or 9.8%

I really think most of the power increase can be attributed to the increase in boost. At the end of the day, everything just boils down to A/F ratio and timing. It doesn't matter much how the airflow gets measured (SD or a mass air), unless of course you have a really restrictive mass airflow sensor setup, as I did with my bone stock 2G intake snorkel a few months back. Now *that* was causing a serious drop in power just because I couldn't hold boost.

Thanks for shedding some light on that Tom, I was looking for you're input and I appreciate it.

I guess better wording would have been, felt like he might have been

I was curious Thomas' input, due to just receiving my program. I know they had talked, so who better to find out the other half of the story!

I have no doubts of it being a phenomenal program, as the two before it. Which is why I ordered it, and I have no doubts it will take me to my goals, and probably far beyond.

Thanks again Tom.

The only other guy that had a problem recently (that John felt might be related to his own) tracked his issue down to a GM MAF installation problem. Is there someone else?

I finally heard back from this other guy on his weekend results. Apparently the original breakup related to GM MAF goofiness was cured as I mentioned before, but he still has a strange power loss that, so far, does not have any clear explanation. He has not posted logs and neither he nor John have been able to free the time/energy to dig into this.

Given that we've been unable to recreate the problem (believe me...we've tried) and haven't heard from anyone else having this issue, we're sort of stuck now waiting until one of those two guys gets time again. But believe me, if it's ANYTHING related to our stuff, it'll get fixed immediately. We're just waiting on some way to move forward.

FWIW, Curt Brown was running 9.4s and 9.5s in the heat this weekend using V3 and a GM MAF. So we know it works on high HP cars. We just have to figure out what, specifically, is causing these two problems. It could very well be an issue with our firmware. I've certainly never ruled that out. Or it could be a problem in their cars. We just won't know until one of those two guys gets time to work on it or someone else chimes in with the same problem.

I guess the best I can say is that we're chomping to get on it as soon as we can...

I just recieved Ecmlink yesterday in the mail, It is an upgrade from V2. I am wondering if anyone has used a macbook to tune or use with DSM/Ecmlink. I have everything installed properly on my comp but when I try to connect to my car, It says port is in use my unknown app and will not connect.

Anyone had a similar prob? Any help is greatly appreciated.
