LCR Blipping the Throttle

[CBass]

I drove a New Leon diesel yesterday and was surprised at how blipable the throttle was, ie. when you press the accelerator the revs rise instantly and when you lift off the revs drop instantly and can be done in a sequential fashion, eg vroom-vroom-vroom.

When I do the same thing in my LCR it is not instant and quick more like vvrrrrroooooooomm (very lazy). I also had a recent incident where I had to quickly nip across a busy road and immediately stop, I set off with revs, but when I lifted off and braked, the car continued to try and accelerate and rev against my braking, almost as if the turbo pressure wasn’t released or the throttle was sticking slightly. The throttle response on the diesel was also much better than my LCR (not sure what diesel it was through because it was a courtesy car).

Is this a sign of a dead DV, is it normal for LCRs or is something else that the garage should take a looky at whilst the car is in?

I did have that a few times on my car, a bit annoying and maybe a throttle body alignment is wirth a try (it's free and takes 5 mins).

Seemed to me to be the cack fly-by-wire throttle VAG system where as soon as the brake is touched throttle is cut....this system seemed to be confusing itself....no fault as such just over complex IMO

Revving at standstill is also different to on the move the turbo doesn't fully spool if there is no 'load' so it's not representative of being on the move in an LCR

 

[Feel]

Yeah, like Steve says. I've had it quite a few times - on the gas, TCS kicks in, off the gas at the same time car still seems to be accelerating (it's not, it's just not fully backed off).

I think it's the TCS returning the throttle back to the position that it was at before it backed the power off, which is not where you've decided you want it...

 

[Ruddmeister]

Ah so it's the TCS butting in as well and cocking things up

More complex than it all needs to be IMO

Throttle response and feel is the thing I hate most about the LCR. Going from my M3 which was sharp as a knife at any revs and any situation, to the dopey feeling LCR is horrid. The fact that the turbo needs a moment to spool up is one thing, and I figured the drive-by-wire throttle is the main cause, instead of a good old cable from the pedal straight to the butterfly.

M3 is a different league alltogether really

Of course it is, one extreme to the other really. But even the throttle on our Fiesta run-around seems to respond sharper than the LCR.

Its like its on elastic - blip the throttle and after a short but noticeable delay the revs will rise and drop (like its taken up the slack first!)

If you haven;t done a throttle body alignment for a while maybe worth a go

As I say though the system is over complex for my liking, technology for technology's sake IMO

 

[Reg]

Never done an alignment. Have read comments about it but I don't know whats actually involved, so I'll do a search. Just seems to have, as you say, made things over complicated. I've never had to do any of this crap on any other car I've owned, and think its rubbish you have to on these.

It's a weak point of the LCR, but the car is a massive compromise in all sorts of ways and isn't any more annoying than say the massive body roll IMO. I suppose if you want a car that has razor sharp throttle respose then old M3, Honda S2000, Clio 182 or something is a better alternative.....Horses for courses really, the LCR is a good family sized cheap hot hatch but it's a compromise

 

[Reg]

Again, you are right. My wife uses the LCR during the week, and she loves it to bits. Don't get me wrong, I really like it too, but when I buy another decent car for daily use it will have to be naturally aspirated engine, and rather more focused than the Leon.

dont hvae issues with the response in mne, i do have issues where the revs drop slowly if you lift off at high revs.

it goes vrooooOOOOOOOOoooooomm instead of vrooom

 

[CBass]

I didn't have an issues with response until I drove another car - It isn't really noticable until you have something to compare it against.

Is the New Leon drive by wire then? as the response in that was much better.

vrooooOOOOOOOOoooooomm - that's the fella that irritates me! If you give it some beans over a few meters and then stop, the car continues to finish its OOoooooomm for a couple of seconds and sounds like you are sat there with your foot on the throttle!

It's the issue Feel and I were describing the over complex Drive by wire, TCS systems etc............new Leon maybe better, search for how to do a throttle body realignment.......which may help

If it bothers you, stop mashing the throttle to the floor, then jumping on the brakes C'mon guys...

 

[CBass]

Yeah, fair play!

It's just a bit odd, I have only encountered the problem twice and wondered if it meant something or if it was normal - which it seem to be.

I won't bother trying to master heel and toe downshifting in my LCR either because it is too hard to accuratley blip the throttle to match revs. It makes driving much more satisfying when you get it just right, especially when on a charge though...

I find response improves massively once revo'd on the 20vt. My ibiza was the same, feels so 'soft' on the stock map.
