No-lift-to-shift ?(DSMLINK) [Merged 3-7]

[4g63telantra]

Anyone with DSMLINK,can someone help me out on what this really means?

The shift limit that you set depends on how high you are reving your motor. I rev to around 68 ot 7000 and i like 5750 the best. The intervals are 250rpm. I find that if i set the rpm at 6000 it hits the rev limiter too soon and the shifts arent as easy and if i set it at 5500 i have completed the shift before the rev limiter is hit. At 5750 it just gives one pop from hitting the antilag and by that point the clutch is on the way back out and im at full boost. Works amazing.

Dont forget you have to wire in the clutch cut wire. For the 2G,

That is a very good point to bring up. Not only does the NLTS help boost responce by never having to break the air stream. But when the timing (limiter) your are selecting kicks in, the timing fires so far past TDC that you get a very similar effect to a stutter box.

Your little flame/pop from the exhaust on the shifts is the kicker for this one.

The ALS option on DSMLink allows you to hold timing at a certain level advance (mine is at 10*) and add fuel for a bit more of a "kick"

Fun stuff!

I think you meant to say timing retard...the antilag retards the timing atdc rather than btdc. You are probably at 10 degrees atdc. It depends on the turbo you are using what you set that antilag value to. I have a small 16g so i set it at 0 but with a bigger turbo 10 degrees atdc will work better. I have not played with the enrichment because even at 0 degrees and 0 enrichment i will build 20+lbs of boost when i bounce off the antilag.

I haven't yet used the antilag feature. Is there anything i should do to my settings if i activate it.

Also, i notice when i do a no lift shift i get some bad knock for a few seconds once the clutch is let back out. Anything i should try with the timing to stop that.

There are a few things that could be causing that. I would check your motor mounts and make sure they are all tight. If they are then i would recommend some type of poly urethane mounts to reduce engine movement. To enable antilag you need to go into the antilag menu under ecu and set the enable rpm. i have it at 5600 so that it enables between shifts but not during a launch. My launch is at 5000 and shift is at 5750...see how that works??? 5600 is higher than 5000 and lower than 5750. On the antilag setup you can put in a negative number that will put the timing btdc. It will still spool the turbo (if it is small) and might help reduce knock. I use -2 on my antilag for timing. The knock you are getting could be from the tranny. On my stock tranny i used to get knock between shifts but now with the stage 3 shep it knocks a lot less. Id assume this is from the tranny being sloppy. Hope this helps.

My car used to do this on the 16g and pump gas, I noticed an airflow spike going into the next gear like the wasteagte couldn't actuate fast enough to keep boost stable. I really only used the NLTS feature at the track so I was usually running race gas anyway.

Wow this is a grat thread with lots of great info. I get how the NLTS works, thanks a lot guys Oh this should be fun to experiment with when my car is finished.

I have been looking at my options for tuning equipment,and the different features between them.
So now im wonering,i have heard a few people say with the dsm link you get the no lift to shift feature.
What exactly does this mean????????
Thanks

 

[nightspeed87]

you can also get that feature with a keydiver chip but you have to do a little modding to the system to get it to work, and it requires a good tranny or else you could be severly damaging your tranny doing it.
Basically it goes with the stutterbox and allows you to keep your foot to the floor while you shift so you dont have to wait for turbo spoolage on the next gear since youll already be spooled from not lifting. It sets a ( selfdetermined ) rev limiter for while the clutch is down and your foots still to the floor so you dont over rev doing it. A good feature if you have a upgraded tranny/ cluthc/ lsd/ and are a serious racer.

 

[VanIsleDSM]

apparently needing a good tranny for NLTS is BS, according to that thread listed here, it can help a notchy tranny.

 

[siceclipse]

Airpoppoff made a really sweet vid about No Lift To Shift.

i searched but the link is dead.

Basicly what happens is you set the rev limit to like 5000 so when you put the clutch in at 7-7500 the revs drop to where you want them and you dont have to take your foot off the gas.


Airpoppoffs sounded like a freaking canon fireing.

Untrue, please try to report actual information instead of heresay. It is actually easier on the trans since the RPM going into the next gear are more closely matched. When you shift the synchros have to bring the next gear to speed with the engine, with NLTS the motor slows the input shaft and lessens the stress on the synchro.

On the contrary,
Read on that link somewhere in the middle of the paragraph its talking about the stutterbox, it says the it does recommend you having a good tranny. This is where I got the info from because this is the chip I have.

I see that now. The OP inquired about DSMlink though, and I have seen a marked improvement in shifting quality using NLTS.

 

[Oneavenger]

best invention ever.

 

[slipstream808]

I've personally found it easier on shifting using my NLTS in my DSMLink. It shifts faster and seems less... "notchy".

Agreed...i have used it with both a stock tranny and a shep tranny... Both worked excellent. That link above is a good one.

 

[RedTurboEclipse]

I've had DSMLink for a while and never connected the clutch wire. Maybe I should. I still keep my cruise control right?

 

[siceclipse]

yes to cruise control

 

[-DSM2NR-]

Ok, well I've heard both sides. Some people say it'll destroy the stock tranny and others say it's completly safe. I want to know the truth aout NLTS.
Is it really safe to use on the stock tranny or not? I'd really appritiate input from those who use/have used it and know what they're talking about. Thanks

 

[pneumo]

It depends on how you use it. I've seen guys who think you have to shift as fast as possible when using NLTS. Shifting fast will hurt the tranny.

The nice thing about NLTS is that you do not have to shift fast. NLTS will hold the rpms up and keep the boost up so you can make sure it goes into gear without rushing it. It takes a little practice before you get used to it.

 

[92awddsm]

I used it for 3 yrs on a stock rebuilt tranny but eventually destroyed 3rd gear. That was shifting as fast as possible.

 

[jpbrazill]

My MSD has the 2-step and NLTS. I have shifted relatively fast, no superfast shifts, and it has been just fine on my stock tranny. If I try to really shift fast, I can feel it grind a bit in between the gears.

[thegchild04]

since when can you have nlts for 2g's?
