I don't understand how this is any different to burying the accelerator into the firewall??? Is this for people with short legs?

[Corey_R]

I'll try and re-explain myself though. I was expecting 20% throttle in race mode to be like 50% throttle in stock mode (random made up numbers), but it just isn't. If I suddenly pushed down on the pedal in 7th gear, the car would go 'oh, um, I wonder why he's done that - now which gear should I downshift to - let's try 4th - off we go' (bit of an exaggeration - but there was a tiny delay and not always a heap of torque (which made me question the reliability of the APR tune a while back, before just ignoring and using Sport mode).

The SB means instant acceleration whenever I want it. Well, it hasn't missed a beat so far, anyway - time will tell if the car goes more docile again later.

Yeah - but that's exactly the point I'm trying to make though Ryan_R, which is now making me even more skeptical.

The SB would change the throttle values, that's a given. But it's very unlikely it could change anything in the ECU (other than the throttle signal it's sending) and I would say it's impossible that it's able to change anything that the DSG is doing (again, other than the difference in throttle position).

I understand what you're both saying, I thought the same thing before I got it.

I outlined the type of person who should get it in the first post somewhere, and I'm happy to recommend it to them, but I'm not expecting anyone to just dump that amount of money for something they haven't tried.

If two owners of different Mk6 Golf's with APR are both happy with, that might be enough convincing for some. Others might want to try the 30-day money-back guarantee. Others will not see the value in it. Either way is fine.

It's easy to say "just floor it", but I don't think I've ever done that in day to day driving or in traffic. If I try to analyze what I've done in the past - I've probably given a good 60-70% throttle and then realised I'm not going as fast as I wanted, so I push down further - which is a slower approach. The SB means I can keep my driving habbits the way I want and get more vroom for less effort. That's why they can say it makes your car 'feel faster' and they're correct. If you customarily floor the throttle, then you have no reason to buy it.

My car now drives much more like a sports car and I love it - haven't had so much fun driving to work in a long time

Hopefully that helps people make up their minds up one way or the other. Hopefully Fab can share a bit more of his thoughts when he finds this thread.

So it can really only change the signals that the accelerator is sending (unless I'm missing something). Some VCDS logging should confirm exactly what it is doing though.

This is the point I made in the main R thread. I think it works based on seeing *any* throttle input and then adding an extra amount, lets call it 25%, 50% whatever. So in effect, it feels like more acceleration and would hit fuel economy you'd think? It can't be doing much else as it's just intercepting the throttle position ?

I don't really want to go driving with a laptop on my passenger seat, so I'll let someone else volunteer to do the logging.

I had my netbook on the passenger seat the last few days for ages doing logging. It's just a pain having to manually select all the variables you want to log every time you turn the car on.

*cough* Start the logging with an automation program such as AutoIt

Hmm and this is why I've been pestering you to start playing with the VCDS!!! I knew you'd be holding out on us with a few tricks! Be nice if VCDS had a quick start logging feature though other programs. I've done a quick edit of my logs to suit the ecuEDIT program, I'll wack up an image of the output later in the VCDS thread, its much nicer.

[Fab_R]

I don't have an R (remember I bought my 118 TSI 2nd hand, so I could never buy a brand new R) - but while I'm sure the fuel usage will go up a bit, it shouldn't be any worse than your fuel bill (which I could afford).

Perfectly explained Ryan_R.....

Put it this way, i would not be without it now...It turns the R's character into a very different animal especially with Stage 2+.

Anyone one is welcome to have a drive of mine to see/feel for themselves.

I keep mine on "Race" and it is totally controllable at lower speeds with smaller throttle inputs.

Also fuel consumption should not be compromised providing you drive it as before.
But once you give it the berries like without SB it will drink more naturally.

As Ryan mentioned, it kicks down far more easier and rapidly!

Make no mistake, on the R, it removes the throttle lag that these things are notorious for.

Nothing to be skeptical about gents, its the real deal and solves the issue with them........Hope this info helps!

[Ryan_R]

Hehe - I said I'd stick to Green/Sport mode - but 5 mins on the way to work I switched back to Red/Race and had a blast on the way to work. As long as I'm not carrying "older" passengers it'll probably be staying there now.

[Fab_R]

Corey what i beleive it also does is move the throttle body butterfly "in real" time, where in standard set up, it seems there is slight delay.
Fly by wire is notorious for not having instant reaction like the old fashioned throttle cable.

Haha - I thought so.
