mechanic recommended this to a friend of mine?
Discussion
Hello guys,
Thought i'd ask your opinions on the following. Personally I thought at first it was another one of them 'make you car go x% faster', and to be honest am still quite dubious even after looking at it.
Was recommended by a mechanic to my colleague when he got his BMW 330CI serviced a couple of days ago.

Actually, I don't think it's all that 'snake oil'. Lots of people on one of the Merc forums swear by it as I think it genuinely does dial out a bit of computer-aided sluggishness pulling away.
Their graph does not seem to suggest power gains, just a difference in delivery.
I guess if it's efficently ripping out a 10 year old bit of tech and replacing it with a new, more efficent and faster way of processing the throttle position it could work, however, I don't really see how it'd be much use on anything other than an older, less sporting car, in which case, why bother?Their graph does not seem to suggest power gains, just a difference in delivery.
From what I understand, all it does it make your accelerator pedal more responsive - e.g. at 50% pedal travel the car opens the throttle 75% or similar. This probably makes the car feel faster as a result of using less pedal travel to accelerate harder.
In reality what it'll do is make it much harder to drive smoothly, since small pedal movements are now amplifed.

It doesn't rip anything out and it's not eactly tech. It looks like it just sits between the pot on the loud pedal and the ECU and changes the input proportionality.No idea what it does but Mustangs used to suffer sloppy drive by wire throttles and that could be dialled out by a change of tune but what and how they do it, i don't know. All I do know is the initial lag vanished and the car was a million times better even if it did nothing else but take away the lag.

t.
^ As has been said, it alters the signals being sent from throttle to ECU and in affect acts like a different throttle map.
Might work if you have an 'eco' friendly car as these seem to have slack in the response to aid smooth driving (from experience), otherwise could drive you mad driving around town.
Never experienced one though so might be wrong.

You might be right, but I read it not as in making the throttle more sensitive, but in making the response time faster. A lot of cars from the 1990s onwards, even those with cables, have a bit of a delay, a fraction of a second, between pressing the pedal and the engine responding, as though the command went via satellite. Drives me mental. I want the engine to answer when I move my right toe, I don't want to wait half a second while the request goes through an approval process.In reality what it'll do is make it much harder to drive smoothly, since small pedal movements are now amplifed.
So all it's doing, as far as I can tell, is removing the delay. Once the response from the engine comes, it's the same.
I'm pretty sure my mother had a 330i E46 with one of these. It was a pig to drive - the merest brush of the throttle sent it off like a stabbed rat, not at all progressive.
A client who made the mistake of parking his new 911 Turbo behind my mother found out to his displeasure just how difficult it could be to control at close quarters.

Nope, it does not know before you press the pedal that you are going to press it. It routes the signal the same way and uses all the same wires. All it does is change the ratio of the angle of depression of the pedal to the %ge of full throttle.Gassing Station | General Gassing | Top of Page | What's New | My Stuff
