I don't know what most supercars these days use buy I can't think of many of the top of my head using DSG, but there must be some.

The Veyron is the only one so far.

VAG (who own Bugatti) were the first company to use it in a road car- The Audi TT.

Although the gearbox in the Veyron was developed in conjunction with Riccardo. Over 50,000 man hours worth of development, apparently.

conventional autos, and CVTs are VERY different to DSG guys.

I don't know what most supercars these days use buy I can't think of many of the top of my head using DSG, but there must be some.

The difference is simple , tiptronics are autos ( with a torque converter and yes you can change your own gears ) DSG'S are manuals with a clutch but you dont have a clutch pedal , it engages automaticaly , you can change your own gears and can also be used as an auto. Its the way things will go in the future because you have the best of both worlds .

Personaly I can live with a DSG and or a manual but NOT with an autospastic.... I have one right now actualy .... autos suck ...

Props on taking the plunge and signing your name on the dotted line for the new GTR Jash.

I'm sure I speak for everyone here when I say we'll be awaiting your cars arrival with apprehension.

Hope you've got a good camera. :)

The difference is a bit more profound than that.

Some M-series Beemers, Ferraris and Lambos have used computer clutch controlled semi-auto gearboxes for ages now- But DSG is a twin clutch setup, that pre-engages the next gear up or down depending on the driving style. The control computer disengages one clutch while engaging the alternate clutch as soon as the other one has stopped driving the input shaft. So you have a near seamless gearshift, and almost no idle-time in the power transmission.

lol, that's exactly what i've been saying... CVT not good. conventional auto not good. DSG very good. DSG is completely different like I said, mainly in that the next gear is already engaged so shifts can be ultra fast.

why does everyone seem to think I have something against DSG?!?! all along I've been saying DSG is excellent and I hope that is what it has.

Well I didn't want to go in the final detail , I wanted to say that they are a manual box with a normal hard coupling , unlike autos that have a torque converter coupling that eats power. These boxes are the way of the future , they are the death of the manual box as we know it now and in my opinion the death of the normal auto as we know it today.

Autos use a lot more fuel than manuals in stop start traffic because of the dreaded torque converter .

DSG ( direct shift gearbox) is the latest of these type of boxes , yes they use 2 wet type clutches one does 3 gears ( 1,3,5 ) and the other does the other 3. The next gear is pre engaged so its very quick change in auto mode but if you want to change it yourself it can be slow when the computer doesn't know when you are going to change, especialy on the down change .

Contary to what people think DSG is developed and built by Borg Warner ( for VW) not developed and built by VW .They will be building them for other car makers as well so you will see heaps more very soon. Getrag is another trany builder that will be building these ( twin clutch boxes), actualy they already have , that could be the one in the new GTR . The new BMs have these getrag boxes in 7 speed , I think they call them DCT.

The BMW SMG and the Ferrari use a different type of box its slower to change gears and both BMW and Ferrari are going the DSG (type) boxes already.

The new evo 10 has a DSG box as well, not sure if its made by Getrag or Brg Warner but its the same set up.

The only uincertainty about these type of boxes is durability but i'm sure they will be made durable and made to hold heaps of torque . They are a little heavier than a normal manual box with the same strength and same amout of gears and cost a little more to make as well. Of course car makers will charge a lot more for them for now anyway..

oh and DSG have been around for at least 30 years that I know of. porsche used them in racing cars back in the day and I'm sure there were plenty of others too.

regardless of how quick the DSG shifts

its just not the same .......

Its not a bad thing. I'm quicker everywhere with an manually changed tip auto, and the best part of a DSG is if you cant be bothered with changing you just snick it into D for Drift and away you go.

My OTP read 140 plus on roads - thats well over 150...

my goodness people, this is a car competing against the worlds best, and you're going to right it off because you can't row with a 6 speed??? :w00t: you'll NEVER be able to shift as quick as these boxes, EVER!

what's an OTP c-red?

      Mate you saved be from dying in the Perth summer. AC wasn't changing direction and just going into diagnostics mode fixed it. You're a legend and I would shout you a beer if I could!

      Unfortunately effort gone to waste, you will have substantial issues with how the manifold and wastegate have been integrated. You would be so much better off with a modified stock manifold like this: https://hypergearturbos.com/product/rb25detexgatedmanifold/   OR literally just getting a off the shelf Sinco or 6Boost manifold as myself and others have mentioned.

      Yuck. But it's kinda the same principle, moving timing around to make car run bad but sound good.... I went for a more spirited tuning drive to iron out a few things. Car no longer stalls, and it loved to dip RPM low when you clutch in. After tuning this (and the 4-5 tables that HPTuners/LS1 OEM ECU wants for idle air correction) it's now behaving somewhat normal. All expected because there's a new TB, new Intake manifold and that new TB which is 102mm vs 78... has an entirely different IAC passage which is smaller because ????? Unfortunately at this point I went to make further fine tuning changes to avoid it flaring up, you know... _tuning_ the HPTuners dongle died. Well to be more accurate - The USB cable died in a fashion that anyone who has ever charged a phone will recognize. After the app demanding I resync it 50 or so times (which all 'succeeded' but all failed) the device does not want to sync and I've logged a ticket with support to see if it's fixable. US Support said it was a 'storage issue' but after removing the SD card inside it and formatting it/fixing it the issue does persist. Unfortunately usually the fix is "Turn in your old dongle and pay $700 for the upgraded one" it's cheaper because I get some free licence credits I unfortunately don't need. However I'm 10 minutes down the road from HP Tuners AUS/VCM so at least I won't need to post it, and logged a new ticket for support over here. Definitely drives different. My SOTP dyno believes it's probably making 310-320kw instead of the 280 before.  It scrambles for traction a little now whereas it previously different. It drives like a bigger cam car up top even though the cam is smaller, likely due to the cam not being advanced 6 degrees. The timing is deliberately low and the fuel is very rich so who knows if this will improve on the dyno. It may, imperceptably. Also funny is removing the pineapples definitely makes the car squat more and axle tramp less. So this behavior of having more top end, squatting more, and scrabbling for traction more makes me think = more power. But I could have just been sitting on the threshold of that kind of behavior before. Time will tell if my butt dyno is calibrated right. I need the exhaust leaks fixed before dyno tune for obvious AFR related reasons - I repositioned the pipes but I'm not confident it's fully sealed even if it is better. At least the car does drive around while I cannot tweak/tune it for now. And I have aircon again. medium success!
