" It is a device that improves acceleration by continuously measuring and converting the digital signal provided by the ECT’s potentiometer, and providing the ECM with a new and altered signal. "



I hope its not a repost.

Sounds like it basically just alters the voltage being output by the throttle. So, instead of the ECU reading 50% throttle at 50% it reads 55% at 50% or something along those lines. I think I'll just push the pedal that extra 5%.

Unless it some how speeds up the sample rate of drive by wire system. Then it might be cool.

I'd like to see some numbers.

So when you are WOT does it give 105%? I think I like the idea of pressing the throttle 50% and getting 50% throttle. I've never heard of anything like this before though.

Sounds like the sport button on the M3. I never used it because it made the throttle too sensitive. WOT is WOT whether you use this thing or not, so I don't see how it would be very useful.

I definitely don't see it making more power in anyway shape or form. It has nothing to do with engine management.

I guess I could believe better throttle response depending on how that gets relayed back to the ECU. I don't know the working of a drive by wire so, I can't day for sure though. I would imagine it's just some type of rotary potentiometer.

Sounds pretty dumb to me, I'd rather push the gas 5% further.

i dont think so, it works in a different way

[schneid4323]

Yeah im pretty sure its like adding a sport button from the e46..... without the button (I think im going to buy one and wire a bypass to see what I can do)

OK, so elaborate. Does it some how increase the sampling rate for the throttle channel? I would think that would be up to the ECU not the pedal though.

When it says it works by altering the voltage that just sounds like it's telling/fooling the ECU throttle is depressed more than it really is though.

They say nothing in the video presentation + they present it on some lousy Seat... imho it's a bullshit. No way I'd put s/t like this into a 335i
