Golf R Launch Control Lag

[Lucas82]

I have recently purchased a DSG Golf R which I must say is a stunning little car to drive.

The only concern I really have with it is the Lag between releasing the brake and the clutch engaging when using launch control.

Is this something that can be addressed or just part of having a DSG?

I've used LC a couple of times and didn't notice a lag, but I was pinned against the seat at the time and maybe missed it...

It has an initial pause which I suspect is to avoid too much impact on the driveline but its really nothing as evidenced by the 0-100 times with LC.

If the car is still new and has under a few 1000kms then give it a bit more time and the car will improve IMO.

[Lucas82]

The cars done about 1600km I will have to have a play around with the launch and time the 0-100.

Coming from a manual I guess im used to it being instant.

Still would have no hope launching as quick and controlled as the DSG in a manual though!

This lag is normal and is part of the DSG operation. I have it in my GTI and noticed it on my test drive with another GTI before I bought the car. I assume it's the same as the slight initial lag in normal driving too.

I've done 13,000 kms in my R and I still get the same thing...probably just how it works.

[John2204]

8,000kms and I get the lag too.

It would be interesting to see it you can adjust the Launch control Max Revs aswell through the ECU.

I know this was possible on certain WRX STI models.

Obviously like Dave_R mentioned there is the risk of damaging the drivetrain if this is done.

Germans like to overegineer everything which is why their cars are so great!

It's not the responsibility of the ECU, it's the responsibility of the DSG's Mechatronics.

You can have the DSG software flashed in a similar method to the ECU though - it's just a much rarer upgrade.

Has anyone had a DSG flash done on a Golf R in Perth?

I cant see anything saying that APR do the DSG flash.

WOuld definately be worth looking into.

It's because it's not an APR product, it's a HPA product.

First of all, apologies for resurrecting an old thread, but I thought I thought it was a better option than starting a new one.

This "lag" makes the DSG Golf R appear to be a much slower car compared to its counterparts on the road.

On paper, the R is much faster than the Lancer Rallyart, however the other day, at a traffic light GP(on a closed road at a mate's farm ) the Rallyart next to me was almost two car lengths in front by the time the R launched. The Rallyart was manual off course.

The 3.2k rpm limit and the soft launch indicates that VW is thinking that drivers will be using LC quite frequently.

So, yeah the LC does not affect the 0-100km/hr time, but that is because the clock doesn't start ticking till the car moves.

What is affected is the reaction time, from the time you release the break pedal to when the car starts moving.

[Corey_R]

Part of a quick take off, whether at the lights, or a quarter mile, is anticipation of the green. That exists whether you are driving a DSG or a manual.

I personally don't feel that the lag between taking for the foot of the brake and it starting to do it's thing with the clutch is anything to be upset about. To me the area that would benefit from improvement is how "soft" the launch is once it is doing it's thing... a combination of the 3.2k rpm limit you mentioned and the clutch slip.

I you are really bothered by it and wish for a harder launch (less clutch slip and higher launch RPM) then you can of course grab a HPA Stage 2 DSG tune. I've no idea whether it helps the lag between brake pedal release and when it starts doing it's thing though...

HPA DSG reprogram would almost be a pre-requsite...Like a APR or similar engine reprogram.

Makes it functionally into a sequential gearbox and eliminates the uncommanded gear changes in ?manual? mode and will hold a gear regardless of your revs.

Lifts LC engine speed and removes the torque limit too.

Still lets auto upshifts at WOT in sport mode if you can't manage by yourself.
I can't remember if it will let you select a gear and grenade your engine though?

A bit of VAG-COM tweeking to discover what can be done about the ESP nanny and the real interdepencies between systems (lateral, longitudinal, brakes etc), a Haldex contoller, springs & dampers and have a nice drive.

This is not correct. Firstly, the downshifts in manual are commanded by the driver. It's just that most Golf drivers haven't read the manual and realise that by pushing past the '100% throttle resistance point', they are actually pressing a switch to tell the car to downshift (kick-down as they call it). Upshifts past the redline are done to protect the engine. Even if you get the HPA to remove this, you'll then hit your engine rev limiter anyway. The main reason that this feature is offered by HPA is for cars such as the R32 where the engine has modified internals and the rev limiter has been raised. In a Golf GTI this feature is completely pointless, as you're already way past the efficiency of the engine. In a Golf R, there is probably a little point (at least for the extra few hundred until you start bouncing off the rev limiter).

Justin Fox recently documented placing a small plastic block under his pedal so he doesn't have to worry about the resistance point when he's at the racetrack. On the vwgolf site he's also having a similar discussion about the benefits of the HPA tune, from his perspective as a owner of a tuned GTI who regularly tracks. (similar comments and reasons I've put btw).


Don't get me wrong, I think that the HPA tune does have its benefits and is highly recommended for the right people and reasons. I just feel some people often desire to get it because they don't realise about the "kick down switch", and the fact the removal of upshifts at redline won't help if any/or much, depending on car.
