Erm Throttle Response System?

Just saw this come up on ebay after looking for a throttle pot, to me seems a tad pointless since its a bloomin landy not an M3. Thoughts?

I like the idea that ... "OFF: We recommend the OFF mode for driving on very slippery road surfaces brought about by ice, snow or heavy rain." Heheheh, not too good for a Landy in the sticks.

Mind, if City mode does boost torque at lower revs then maybe it's worth it .. maybe ... especially if you're towing heavy loads or always carrying a full load. Especially if you can change modes on the fly.

I'd, if I had a TD5, be interested, but I'd have to try it first before handing over the money ..

I suppose you have a point, but can the pedal adjust those features that much to make a difference?

I'm guessing it works fairly simply by telling the computer that the Throttle position is different to what it actually is, TD5 being fly by wire.

A better way to do it is a proper re-map and tune, but to do it properly is bigger money ..

So not as ridiculous as I first thought?

Not completely, but probably not worth that money, maybe worth a try if it were more like £50 .. but at £185 I'd like to know exactly how it works and what it feels like when being used .. I guess it's like the difference when we used to change the throttle cable and twist-grip on trials and Motocross bikes for a quick-turn throttle for faster response, or change the cable-cam for slower response, this just does it electronically.

I like the idea of a user-programmable mode, if it allowed, say, high torque at low revs with slower throttle response but higher power at higher revs with faster response .. or swap that about and try to lose turbo lag for slower speed, uphill sections, maybe .. lots of possibilities for playing and tuning, but it's only one part of tuning a system and it's hard to see how it achieves what it says it does.

The again, couple this with a properly programmable ecu and it'd be real fun ..

Hmmm I wonder if there is anywhere where you could test it out... Does seem interesting now it has the Landyzone seal of almost approval lol

TD5s have something like this built in

gentler in low box, more agressive in high

It can't give you any more power and torque than it would anyway, but they do make a difference to feel. The new MINI comes with a three way response selector and the sporty setting 'feels' more powerful even though technically it isn't.

Absolutely, no extra power or torque, it just 'moves' where it's delivered up or down the rev range, which gives the impression of more, which makes it arguably more useable.

Hmmmmm I am becoming more interested by this now. Though like you said im not dropping 200 notes on something that could well be a total waste of time.

If I had a TD5 and if I wanted something to do this, I'd maybe get a spare TPS and ask a tame electrician to work out what resistors/diodes/whatever they are, need to be fitted and where to achieve a 'different' reading ... or, like this could be if it were simplified, take the wires from the TPS, connect them into a blackbox of my own making, with some kind of adjustable resistor pot and re-connect them into the system to try it. Just 'cos a ready worked out solution costs £200 mostly only means the accountants have had a go at their pricing strategy .. Something like the old Trainset speed controls that used a rheostat with a single speed adjuster that works as a 'torque adjuster', ie moves the sweet spot up and down the rev range.
Just a thought, but it ought to be easily doable ...
