hello2all,

been researching throttle boosters, esp. tsbooster v3.0. i talked to a guy at pedal commander and he seems to think that the c5 can't be throttle boosted. anybody have an idea why we can't join in on the fun?

thanks much

 

Why would you waste the money on one? Press the pedal down further. Same thing.

 

Don't know if is a waste of money to do it to a C5, but I knew a guy that had that on his C6 and he loved it. I drove it and it just went when you pressed on the gas.

 

Yeah, that's what the gas does.

Floor it. Same thing. You can't ever make it have more than 100% throttle input. All those things do is make the throttle motor think you're giving it more input than you are.

 

My C5 goes when I press on the gas too. No need for a pedal commander on these cars.

 

Corvettes of westchester used to do something with the tuning similar, called it the CoW booster or something. I see chuck hasn’t been on the forum in quite some time but when I googled it the business still came up as being open.

 

No lag in a C5 pedal.

All joking aside, some newer (than the C5) vehicles do benefit from "pedal commander" type devices due to the programmed fuel saving/emissions/other gov't rules in their PCM/ECM modules.

 

There is no throttle booster available for the C5. It has to do with the OS and throttle controller. I am not an expert so that's about as good an answer as I can give. You can use hp tuners to alter some of the throttle position sensor tables, but you can brick your computer and have a major problem. I think it is pretty good as far as throttle feels if you dont feel that way look at the reasons your car may not be responding. It may have to do with cleaning your maf, Throttle body, spark plugs, etc.

 

I have one in my daily(C6) and happy with the purchase. It fixed the severe lag there was when I mashed the gas. The multiple settings are cool and you can tell a difference with most of them. With that being said I paid $100 for a new one, but wouldn't spend more than that for a similar product.

 

Of course there’s a lag time in a DBW throttle. For those who haven’t experienced what a DBW signal amplifier ( there are many on the market AKA pedal commander, pedal monster, sprint booster etc. ) it does make a positive change.
Of course there’s a rubber band effect. The speed and the amount in % the throttle body opens is atrocious and for those who haven’t used one don’t feel bad. The difference is real and it feels much stronger because the ECU is stealing from the entire cars performance. A signal enhancer merely puts back whats the car is truly capable of
So yes a signal enhancer will increase sensitivity while at the same time allowing a greater amount of throttle percentage which will make it rev faster ( I mean it will take less time to react ) while adding some additional air and fuel by opening wider ( instead of a lazy rubber band you get a snap with a larger, higher % throttle opening.
FWIW; I’ve gone down this road years ago fellas. I’ve used a Sprintbooster for over 10yrs. I had 3 separate cars with the present one being a Mercedes R230 V8 7 speed trans
I laugh when guys say there’s no lag; just step on the throttle or harder or you can’t get “More than 100%”. Fact is it’s Not actually 100 % unless you punch the gas and Leave It there. We’ve evolved past that years ago.
Part throttle applications never are what the amount you aim for.
With a signal amplifier It’s the “speed it reaches” 100% and the larger % of PT opening that will leave a smile on your face. Not the brick on the gas pedal philosophy. Nobody drives a car with gas as an on/off switch. It’s the low, part throttle acceleration from a light most people want to improve, not 1/4 mi. Type blasts
Fellas, you forget about speed. You need to wrap your mind around the idea the DBW has already STOLEN the quick reaction your engine truly has. Not only that but the factory ECU claws back the amount the throttle is also slowly opening lesser than it is capable. Meaning it CAN be faster AND It can also open wider.

 

Sorry I can’t except that

 

Going back 50 years, slot cars beat everyone to drive by wire, i.e., you used a hand held controller to apply the "throttle", which was actually a variable resistor/potentiometer, whatever. So I invested in an expensive hand held called the 'Endura Vari-Power. It had an adjustable sliding switch which varied the ohms of resistance. Of course, I set it for the maximum response. Never saw any difference. I'm sorry, but I think a lot of the seat of the pants gain here is actually a state of mind. I would LOVE to see a before/after comparison in the 1/4 mile, same car, same day, back to back. I doubt there'd be any difference. My .02......

 

Proper throttle modulation is one of the hardest things to learn when a person first starts driving a high performance car, verses an under powered car that you can floor board at any time without repercussions. It’s one of the key driver inputs to achieve faster lap times verses losing control of the car because of too much throttle input at the wrong time.
Chevy got the throttle input control just right on my ZO6 for my taste, overall it's one of the most balanced and forgiving high performance cars I've ever driven.

 

It's true you press the gas then it goes. How it goes is a different story. The C5 has torque limiting. So until someone plots throttle opening vs pedal position we don't know how far the throttle opens as the accelerator is pressed. It's not one to one for sure since the nannies limit the delivered tongue. The C6 I drove was quite responsive to the throttle and it had the throttle commander. LS3 is a very nice motor. I'm not not saying the C5 needs this but it seems the auto guys could use some help.

 

This.

 

"brick your computer"... what's that?... and cleaning "my maf"..... OK?

 

Popular misnomer is it will add HP/TQ to the overall #'s. Not designed for that. Because it's for PART throttle openings. NOT WOT.
I know people get stuck on old "just floor it" mentality but think like the DBW throttle is being "floored" or pulled with a big rubber band. So dumbed down; what a signal amplifier does is shorten up that elastic allowing you a fatter throttle opening sooner. Won't give you 110-120% just make it happen quicker and (this is where I know I'm gonna lose the George Bush, A.D.D crowd) a larger or fatter "PART" throttle opening. Big, big point Part throttle. Faster and fatter. THEN if you keep or increase the throttle opening the ECU catches up with the enhanced signal and they blend together. It's the SPEED it opens and gives a fatter PART throttle opening that makes it feel like you got a little extra sumpn'-sumpn' there than you did before.
I know some find it witchcraft but fellas it does make your car feel like it's got more grunt. It's like poking that ol cow with a cattle prod. It will make Bessy move faster out of the gate ( meaning Part throttle tip in) than she did normally BUT, NO I doubt your going to turn a faster 1/4 mi. Signal amplifiers are not adjusting the timing or fuel tables so there is no bump to the high end peak #'s.
So if you like the punch it- wait wah feeling don't bother. You won't know what your missing but think about it.

 

It works!!
