Throttle Controllers

Hi Guys :)
I have a theory that throttle controllers such as iDrive have to be a big fat scam.

Modern cars feature fly by wire, and their accelerator pedals contain a spring, and a sensor that is just a variable resistor.
These boxes are supplied with power, and interface between the accelerator (or throttle position sensor), and the plug that normally plugs straight into the throttle position sensor.

So how can this box claim to reduce “throttle lag” or do anything at all that can’t be reproduced by different pressure of the foot on the pedal?
Anything I’m not considering here?

I understand that this thing could, and obviously does indeed remap the resistance curve normally presented by the TPS.... but the claims of these things seem to imply further than that.

Never heard of them, but it sounds like it does exactly that, remap the curve to create a feeling of more power. Back in the carburetor days it was common for gearheads to mess with the linkage to make the throttle open more aggressively, it made the car feel really punchy off the line but it was only an illusion, obviously it didn't actually allow the engine to develop any more power, it just made the throttle more twitchy.

I’m not actually sure if this kind of link is allowed, but I’m obviously not advocating it. They aren’t cheap either.

I figure most vehicles would work this way nowadays, and mine is one of those. I’m in Facebook groups pertinent to my vehicle, and these things come up often,
as do adds for the things in my feed.
There are videos about them with a pair of identical cars racing each other etc.. or the same car with the device enabled/disabled.
This is where I think things are going way too far. many actual users swear by them.

There are people that deliberately put some controller in between acceleration pedal and throttle body.  :palm:
Gregg:
What we really need is a controller that shuts down the throttle whenever the brake pedal has any pressure on it....to get rid of the idiots that can't keep their left foot off the brake and their brake lights are always on.  >:D  |O
