Double hinged gas pedal fix?
I find the double hinged gas pedal in the corvette extremely annoying, the fact that the pedal can move and no throttle change occurs drives me nuts. Besides just ziptieing it so that one of the hinges doesnt move anymore is there any other fix for this thing?

You do know that the gas pedal isn't mechanically connected to the throttle? There are accelerator pedal sensors in the gas pedal assembly that send signals to the PCM and TAC modules that electrically control the position of the throttle. These modules determine how much to move the throttle not the driver.

This is irregardless if the double hinge is preventing a throttle cable from being pulled or preventing a variable resistor from showing a change, doesnt matter.
I don't think you realize what I'm talking about, if you do then your posts was totally unrelated to anything that I said. What I'm talking about is when you push the throttle the plastic front of it can pivot and the actual throttle pedal arm stays stationary.
Double hinged throttles belong in grandma passenger cars.

I ziptied it today to see if it made a difference like I thought it would and it made a huge one. Does this not bother anyone else or something? I could barely drive the car because I thought I was giving it gas because the pedal was moving but wasn't.

Same here.
68k miles in C6's and it just seems like a gas pedal to me.
Is OP driving barefoot?

I remember the old gas pedals hinged from the bottom, didn't they do away with those for safety reasons? Maybe they did it so women could drive in high heels.
Actually, I think the Vette's gas pedal is on the plane where it is so that you can heel and toe for downshifting. I know my Vette is a lot better than my Trans Am was for that purpose. I just checked, and if the Vette's wasn't double hinged, you wouldn't be able to get WOT - the pedal pushes in at the top through the extra spring pressure for the final 20% of its travel. Kind of like my old Quadrajet, you could tell you were getting into the 4 barrels when the pressure on the pedal got stiffer.
When yours is zip tied up (I'm assuming you zip tied it at the top so the bottom of the pedal is higher than it normally is) can you still do heel and toe downshifts? I would think your foot would hit the side of the pedal.
I guess if you don't heel and toe, what do you care!

. Its definitely for comfort. I really can't believe this doesn't bother anyone else on this forum, I know it bothers some people I know, but cute comment.

I've owned almost nothing but BMWs as my regular cars, so I can see what you mean. Any pedal movement= throttle change. Even though I drive my E46 every day, the C6 pedal doesn't bother me for some reason. Its very similar to the Lokar gas pedal I had in my '67. If you push on it a certain way, you really aren't doing anything. I don't think its bad, just different.

Booster - I think I understand what you're saying. I could see depending on how you "rest" on it, or how you place your heel that it might have a dead feel, or wobbly/laggy feel.
I haven't perceived any of the above problems though, but I am curious to mess with the pivot a bit so it's less active, see if it makes any dfference to me or not.
why not, just something to tinker with in terms of customizaion.

I know what you mean, but my foot always rests in an even position on the pedal, so I never really get any of the hinge motion. If I drive barefoot it bothers me a bit...but that doesn't happen often.

I'm used to planting my heel on the floor and pushing my toes forward to give throttle, do you slide your heel on the floor?

I wonder if that is why I've been having trouble driving my Z. I've only had it a few days and the first thing I noticed was that the throttle seems very numb in the first 5-10% or so of travel - right where one would need to be for smooth street launching and shifting. My 90 is very responsive on the low side of the travel so this is a bit strange to get used to. I might have to just pay more attention to where my foot is next time I take her out.

Here are a lot of details on that for those interested. It was a great change for my 05.

I think the factory stopped making the Vette throttles lazy with the later years. As I recall 08's and up were set for aggressive ramp rates.
But if you've got an 05 then a tune will do wonders for your throttle response, but you have to be sure to tell the tuner to get the beta from HP Tuners and adjust this table. EFI live has this table as well but it might not be part of a "normal" tune so you have to mention it to your tuner.

Whether its cable driven or DBW doesn't matter, you push the throttle pedal the throttle should move.

No, I did not know what you were talking about and probably still don't. I have never had that issue. When I lay into the throttle I get the response I am expecting. I have no issues with performance shifting if you mean heel and toe downshifting and I do a lot of heel and toe downshifting. As for comparing to a BMW I have only driven a few students M3s at about 70%. Never noticed anything special about their throttle except there wasn't enough power.
