had the misfortune of a learner accedentally standing on the throttle peddle while in neutral today, and beleive me , no ammount of shouting got his foot off it in good time as he was adjusting his weight and thought he was standing on the floor! be aware the red sector of the rev counter is easily achieivalble! (no rev limiter apparently!?0 lol..... pleased to say, this caused no ill affects whatsoever *wipes brow.........

(no rev limiter apparently!?

:eek: I thought there was !!! :confused: :confused: :confused:

There is a limiter, but there's fat lot of good hitting it, unlike a petrol.

Think the learner may have given it a good de-coking for you.

no rev limiter apparently

My understanding is that the Furby has a fly-by-wire throttle which is actiually a digital potentiometer which adjusts the 'throttle' opening in what I presume is 256 steps. My VagCom logs show these steps to be 21 RPM apart. Thus 256 x 21 = 5376 RPM is the maximum you can demand of the throttle, so is effectively a rev limiter.

Anybody care to confirm this?

Sounds Intresting................can any of these figures be altered by a VagCom to improve performance?? If the "Steps" @ 21 RPM could be altered would the car accelorate quicker?

No.

No.

I remember you saying this from talking to you at a meet! (and thanx for making my doors lock by the way ) :)if it was in neutral, could the simple momentum of the engine have taken the revs above this?!

No

Digital potentiometer? :confused: Blimey, those germans.

I once trapped my driving instructors foot under the clutch pedal as I was about to start the car. He was not amused. The bruising took 2 weeks to go away.

Ah, dual controls. It never crossed my mind because I learnt to drive before dual controls had been invented, there was no need for them because driving instructors were truely fearless martyrs of the road, and totally indestructable.

Hi

Wierd coincidence that. I had a guy do similar today for the first time. Stood on the gas instead of the brake pedal. First time it has ever happened (in any car I taught in). The revs went round to just over 5K.

As for the potentiometer, I would expect its output to relate to load, not engine RPM. Half throttle in neutral would not give half revs would it?

Chris

PS He should be able to get most of the front teeth capped and the nose reset.

Jeez, was the car in gear when this happened? 3rd or fourth would have resulted in spectacular results!!!!!!!!

Fortunately not. However, the vRS cuts the fuel as soon as you hit the brakes, so when learners get the wrong pedal (which is in my experience very rare) a quick dab of brakes shuts the engine off nicely.

Chris

Deisels dont have rev limiters as you would expect in a petrol engined vehicle (their is no spark or ignition to cut), the fuel guvernor (pump etc) acts as a limiter in that it wont let enough fuel in to rev any higher.

I thought he ran in front waving a flag!!

Imagin learning in a Fabia vRS, lucky sods :(

Does that mean you can't do left foot braking?
