Throttle lag resolution

Featured Replies

Anyone actually know of a way to alter the throttle response timing without getting a full ECU remap (i still have dealer warranty)? Some people have mentioned changing a code to Audi, is that not the same as setting the throttle to linear when it is set to progressive as default, I've done linear and the lag is still present, you just get a kick up the butt when the power does come in. Throttle boxes don't work, they don't dictate when the power comes in, they just fool the ECU with the position the throttle pedal is in, so if your pedal is at say 25% it tells the ECU it is at 60% for example, so when the power does come in you again just get a bigger kick up the butt. The delay is real, while it can feel like 2 or 3 seconds when you want to pull out on a busy roundabout, it's probably about 0.5 seconds but you're in panic mode, it must be a safety and/or longevity thing, to make you take less risk (but it can actually put you in more danger if you don'taccount for the delay), or is it to preserve the life of the DSG, flywheels, whatever?

Are there not any 'Driving Modes' / settings on the vehicle.

 

A similar mention the other day mentioned  'Progressive' and ' Linear' settings and seemed most, including me, use sport mode. Different vehicles though, different manufacturer for me.

 

I mentioned that the car now 'Goes' when I press the 'Go' pedal.......

I always use sport mode, i did the throttle change using Carista.

Ok. Makes quite a difference to throttle response in my 1 series, from Comfort mode to Sport mode .......

 

Hope you find a solution. :)

VCDS:

Direct Acceleration - Throttle response
With this mod, you can change the behaviour of the accelerator. Option B provides a more linear acceleration without sudden deliveries.
1. Module 44 - Power Steering (Code 19249)
2. Adaptation
3. Select - switching driving profile
Choices:
A - Gradual, controlled by time
B - Directly controlled threshold value

Sounds like what I've done with Carista,  but the lag is still evident. I'll have another look at the customisation when I get chance to make sure it stuck.

Watching this with great interest...  I have also seen on some page that there is supposedly a setting "audi response" vs "skoda response" in the vcds, but could never really find it.

Remember reading on some Polish forum that guys changed this and it was additional improvement, further reducing the throttle lag, tried to contact the guy who wrote the post, but since the thread was few years old, he probably never seen my questions...

 

Anyone had other ideas how to reduce the lag? I am driving mainly in sports mode, but even then it's really noticeable. In "normal" mode, my skoda is unbearably slow, drives almost like an old volvo xc90 with "Geriatronic" gearbox...

 

Apologies in advance for being the grumpy old man in the room... but the Kodiaq isn't a sports car. And if you can't factor in the throttle lag or any other characteristic of the car you're driving when driving it safely, that sounds like a problem with the driver, not the car. The car is set up to behave like a large family SUV, not a Porsche 911.

 

And this from the owner of a vRS, which as I've said before (and will undoubtedly say again) is still not a sports car - it's a perfectly capable Grand Tourer, but anyone who expects anything else really should have bought something else.

You want sometimes the car react immediately, specially in urban traffic. The default setting for throttle response is ridiculously slow, even dangerous in some occasions.

Nothing to do with sports car feeling.

I'd argue that if you need the throttle to react immediately, then you've already failed. If it was the brakes that didn't react immediately, then I'd agree wholeheartedly with you.

You just cannot undrstand. You have developed infrastructure of road network in UK. Dual carriegeways everywhere etc.

We suffered 50 years of soviet occupation here. No one built the dual carriegeways here this time, missle silos were priority one.

Overtaking on simple 2 lane road is becoming a challange. Throttle not behaving as it should be could be fatal.

personally I have no real issues but then I have a manual gearbox.

 

My thought is therefore that it's a DSG take up issue that people are complaining about - and that's an issue common to most automatics, regardless of type in my experience.

There are chiptuners, who offer special throttle boxes. Like this: https://www.racechip.de/gaspedal-tuning/xlr.html

There are more, just cannot remember all of them.

They don't work as I've explained, they cannot dictate when the power comes in.

That is very grumpy, some might say you're trying to sound insulting without trying to be out-right abusive, and you're completely wrong. If you don't have anything productive to insert into the conversation why interject?

Well, manual Lambo (Gallardo if I recall correctly) is slower, than the one with DSG.

That'll be down to gear ratios and, if I recall correctly and you're talking about 0-60s, whether a gear change is necessary.

 

I still maintain that the issue is how quickly the DSG take up is from standstill after you press the throttle and how that is controlled by the electronics, as opposed to having that control via a manual and clutch (a manual it can be partially engaged before you even press the throttle whereas a DSG will only engage after you press the throttle.  Just my experience from driving both versions...

RS has a launch control feature, which is pretty explosive, faster than manual with clutch. But of course you do not use it in everyday commuting, looks more than ridiculous.

Emissions.

 

I recall a French diesel hot hatch that I borrowed for a time sensitive dash around 2003, it had a pneumatic damper on the throttle pedal, if you slowly opened the throttle (good for emissions) the resistance was only that of the return spring, the faster you depressed the pedal the more resistance, if you mashed it as I was doing it was like trying to kick wet concrete, at the end of the very short quick drive my shin was aching and the next day it was like I had used a new gym machine.

 

With a DSG you can have an additional lag if for instance you are in an intermediate gear either maintaining speed or gradually accelerating, the gearbox will have predictively pre-selected the next gear, an upchange, if you see an overtake opportunity and mash the throttle the gearbox has to change ratios on the non driven layshaft before engaging and disengaging the two clutches.

 

The same lag will occur in top gear of the road speed and speed the throttle was fully depressed calls for a downchange of more than one ratio.

Edited by J.R.

the lag is obvious on my car, too; it was brought up by someone over the weekend when punting the car sideways across the ice. They were driving an X3 directly before my car, and the difference was apparently obvious. Within a slide the dead space isn't as much of an issue as you're already dictating attitude from the throttle, but it's disconcerting if / when trying to modulate power to allow grip to happen and I didn't see / feel any difference in Snow or normal mode. Pulsing the throttle simply didn't work that well. Will have to take the opportunity to test when it presents itself again.

 

It's very obvious when you want to overtake on A roads (which is 80% of my 400km commute) - you need to either mash the pedal a good half-second before you want power or drop 2 cogs manually and push from there. Even with that, there's a certain amount of dead space at the top. Annoying when you have a small handful of good overtaking opportunities in 45 minutes of driving (that would be the E63 from Jyväskylä northbound).

 

I've experienced the same problem but only when pulling away from a crawl at say an island where you're in 2nd gear, there's not even a gradual pickup when you want power, it gives it in one shove after what seems like an age just as others have said. This I find dangerous.

It's well reported by lots of Kodiaq drivers on social media. The Carista setting hasn't made any difference on my car. With overtaking at speed I can easily plan for that.

Pedal boxes do have good reviews but you need to fork out £200 to find out.

My Kodiaq in Sport mode is not too bad, but normal mode is just ridiculous. I understand this is not a Porsche, but if you need to plan ahead to press the gas pedal to account for something like 1s lag before the car says "ooooh, we're driving now, ok, let me drop the gear" , that is just ridiculous. What annoys me even more that most of these things is just programmed in a very bad way in the ECU straight from factory ...

 

Since some more responsive settings are available in VCDS (allegedly), I am simply trying to find out what they are and "improve" my car :D

 

My old Geriatronic (XC90, 2.4D, 165bhp) was one of the best cars when it comes to usability, but driving was seriously dangerous. The throttle lag was (measured) 2s! Trying to merge with the traffic was always increasing my pulse :D Was ok-ish driving on the Scottish roads, but one travel to Europe and few hours of driving on German Autobans was more than enough, sold the car instantly when I got back home :D 

 

I have done BSR remap, activated direct throttle control and in Sports mode the throttle response in immediate. Normal mode is bit more mild, but nothing bad, compared to the out of the factory mode.

Can you explain what you mean by bsr remap pls?

I second that, all I can seem to find is a tuning company rather than a component, is that correct?

Correct, it is not a component but ECU remapping.
