The Soler has just as many, but at least they're logically laid out.

 

I like that with the Soler I didn't have to mount the controller anywhere, and can just use my phone to change settings. Which I rarely do. Once each person finds the sweet spot for them, they'll probably just leave it there. The only time I change mine is if it's going in for service. Then I set it back to the factory setting.

 

This is an update of that moldy old “hare-trigger” throttle trick Detroit used in the 80s to compensate for weak engines strangled by the EPA. It was non-linear progression of the throttle. Opening the throttle 15% really opened it 75%, making one think you had a high performance engine. The other 85% of the opening gave almost no additional response. It was lame then, and still is.

 

That's not even close to what these devices do.

The fact is that today's car throttles are exactly the opposite. 50% pedal is about 25% throttle. And even with these devices, the mapping is still less than linear in most settings. Try learning something. And don't comment on how effective they are until you've tried one. Posting from a position of ignorance doesn't make for a good look.

 

Sorry, but I was involved (worked a consultant for a law firm suing Audi for the 100 pedal sticking) many years ago in what ended up being why they started drive by wire. There is a delay (every modern car sold today has it) when you put your foot on the pedal and it is intentional. At times the sytem gets confused and you can actually (usually when you are already moving when those delays seem like you are pushing the pedal and it just takes a second or two to react.

 

There's no "delay" in the C8's throttle, what there is is a very slow tip-in at part throttle openings. If you're at speed, at larger throttle openings, pushing the pedal gets an immediate response, with no delay at all. Where one might think that 25% pedal gives you 25% throttle, and 50% pedal gives you 50% throttle, etc., the real response is very non linear. 25% pedal might only give you half as much throttle opening, 50% pedal might only give you 30% throttle. This is done not to deal with "pedal sticking," (which isn't what caused Audi's "unintended accerlation" problems - those were conclusively demonstrated to be drivers pushing the gas instead of the brake, because the pedals were much closer together than on most cars), but to make cars, especially powerful cars, easier to drive gently off the line. And this slow tip-in makes a Corvette feel like a Subaru at small throttle openings, with a significant lag between what your foot does and what you expect the car to do.

Throttle controllers, very simply, increase tip-in, nothing more. So instead of only ~ 12% throttle at 25% pedal, you're getting a more linear response. The response is adjustable, so at most settings it's still non-linear, just not as much. So at 25% pedal you might get 20% throttle, and at 50% pedal maybe 45% throttle. (Both numbers just examples).

I was very skeptical of these devices for years, repeating themantra "it's the same as just pushing the gas pedal down more." Then someone convinced me to try one. Believe me, it's not "just the same." It's makes the car feel like a sports car should. Does it add measurable performance? No. But neither does the NPP exhaust. And just like that exhaust, it makes the car feel more like a sports car should feel.

If you haven't actually used one, you don't know what a difference in feel it makes. And you're no more qualified to rebut that statement than I am to describe what driving a Ferrari feels like.

 

I may be the outlier here. Had the Sprint Booster in the C7 and moved it to the C8. Completely compatible. Very happy with it.
