Like many, If one knew why or how, and cared.... one would know! and then one'd care that the Corvette is doing what it's doing!.... Lag! Smoke and mirrors (and tuner mumbo jumbo) not gonna remove the lag till one removes its cause.. and that's next to impossible on the C5 Corvette with its designed ECU..... The lag is NOT gonna go away. There is no cable operating the throttle, the control is circuitry.... Electronically controlled by Sparkie and his Wizards!... Sometimes... one must drop back 10 and punt.

You're right. We're all wrong. There. Feel better?

With and without a throttle controller, stomping on the pedal to the floor is identical. You cannot give it more than 100% throttle. The throttle controller can only send a 100% throttle signal. There isn't an extra message, like "100% throttle, but do it faster please" -- the signal being received by the ECU, which ultimately drives the throttle body, is an amount of throttle. There is no mechanism by which to increase the speed at which the throttle plate physically opens that a throttle controller can adjust.
If this is correct, can we not do it in the programming so we don't need the devices?

I'm feeling like this realization is exclusive to fewer and fewer people these days.
Correct on all accounts.
It's a pretty common practice across OEMs of budget/economy cars to have really touchy throttles because it fools people into thinking they're "sporty" -- until you realize the remaining 60% of your throttle pedal doesn't really do anything. Never understood why someone would want this, personally... it just makes the throttle pedal less precise. Give me a scalpel, not a hammer.
If you are hitting 100% from 0%, your wheels might be spinning so while it makes a great display, it does nothing. Could it be that these fooler devices, whether it is the TB or the Pedal Commander are doing is to change the equation slightly before WOT? Without them, when you depress it to X%, where X is less than 100%, you get Y% of throttle opening. Maybe with the foolers, when you hit the throttle to X% you get an opening of Y% +Z% so it feels like it is opening more than it used to?

Throttle response
Sorry to slightly get off the subject but this reminds me of a similar experience.
Back in 1970,when I was in the Army, I bought a brand new Opel Kadett station wagon at the local Buick dealer.(They had the franchise back then). I had it in their shop a few times and got to know the “Opel Mechanic” pretty well. He told me that most times when he worked on them for any reason, he would tell the owners that he “tweaked” the adjustments to make the car more peppy. He said they almost always said they were amazed with the improved performance.
Back then the throttle pedal was mechanically connected to the carburetor and all he did was adjust the slack out of the linkage so the throttle would open slightly sooner when you depressed the pedal.
Sounds like he was ahead of his time. 😂😅

It’s probably hard for most of us to determine real world differences with the throttle controller at “the track.” A more likely test is whether the time to the grocery store is faster. Yes. Yes it is. When you need Metamucil and Doan’s pills, fast is no longer relative.
