Just would like some input if anyone has ever used one of these on a 09 ZO6. Supposed to give you increased throttle response according to the MFG.
thanks

 

Aren't these just the gas pedals they took out of Toyotas?


Sorry couldn't resist.

I know there is a table to control acceleration ramp rate that you can adjust in HP Tuners, my 05 was factory tuned to be sluggish and I increased the throttle response nicely. If I recall correctly and I think I do, the 09's don't have the table tuned to "sluggish" like my 05 was. I think mostly only the 05's had this, other years I've looked at were not tuned for sluggish response.

I wonder if this device just increases the voltage from the factory gas pedal (aka rheostat)? I'll be interested to see what others say as they chime in to this thread.

With all the hubbub and class action lawsuits over unintended acceleration with drive by wire systems, it's kind of ballsy for someone to put out a product that affects the factory drive by wire system it seems to me!

 

Funny that was the first thing I thought about also regarding the Toyotas.
If it is just a rheostat it is pricey at $329. It will be interesting reading I hope. I have been searching for performance mods and found Edelbrock is coming out with a E-Force supercharger for the Z06 in Sept.

BTW Hope everyone has a wonderful 4th of July and remember our troops present and past this weekend. Somebody died for all of us.

 

I have one on my '09 ZR1 and love it!!!

Like Joe_G said, you can tune the throttle tip-in to make the throttle a lot more responsive.

I had a tune on my '05 coupe and '06 Z06. The short throw shifters (B&M in the '05, MGW in the Z06) and the better throttle response were the two best things I enjoyed when driving those cars.

When I got the '09 the throttle seemed very sluggish. Due to potential warranty problems with a tune (and I don't plan on any mods on the ZR1), I didn't want to tune it - at least not yet!!

So.....I got a Sprint Booster, and it worked great - actually too great!!

I initially got one that did not have the 3 modes that the current one has.

The first one I had gave very much increased throttle response, and I think it would be great on an LS2/3 or even LS7, but on the LS9 I had to be careful with throttle inputs, especially in the wet.

I saw that they came out with one that has the 3 modes (OE, Sport, Race) and called them to see if they would swap mine for a new one. They said no, but gave me a nice credit toward the new one with proof of purchase of the old one, so I hunted around and found my old invoice and ordered the new 3 mode one.

I sold the old 1 mode one to a member on the forum. He said he might get the 3 mode one and sell the old one, so check the For Sale section to see if he puts it up for sale.

The 3 mode one is OUTSTANDING!!! As I mentioned above, I think the one mode would be great for a base C6, or even the Z06, but the 3 mode one is good because you can just push the button to put it back to OE mode if you let someone else drive the car, or let a valet park it.

In the ZR1 I run it in Sport for normal everyday street driving.

If you do not want to tune the car to avoid warranty problems, the Sprint Booster is a good solution to increase throttle response.

However, if you're gonna get a supercharger you won't be worrying about the warranty, and you'll be tuning the car anyway, so you can tune the ramp rate to get better throttle response then.

I can't speak for Z06s, but I have one in my 09 base coupe (6 speeed auto) and the improvement in throttle response is absolutely incredible. Of the minor modifications I have made (air filter and intake hose), the Sprint Booster is the most noticeable. I would recommend it without question.

 

Ok I ordered one and am trying to get the OEM connector unplugged! Any ideas? There must be a clip of some kind in there holding it but I cannot get it to release.

 

Oh yeah!!!! It's an incredible PITA!!!!

There's a gray clip that has to be taken off, then you still have to get a small screwdriver in the plug to release another latch so you can pull the connector apart - did I say it's a PITA!!!

I had to remove the accelerator pedal assembly to do it, and it was still a PITA!!!

The pedal assembly is held in with two bolts (I think they are 10mm heads), and once you get it out there's a clip that holds the wires up under the dash. You can pull the clip loose so you can extend the wires out a bit to work on the pedal to get the gray clip out, and then try to release the additional latch to get the connectors apart.

Good luck!!! Let us know how it goes, and what you think of the unit.

I would try one but their Corvette tax is too high for me.

 

OMG! I got a little person to get that thing in! All I can say is WOW!!! If you don't have one of these then you are spending too much money on other stuff! It will without a doubt make you change your pants!

 

I don't get it. Once you floor the pedal, it shouldn't matter.

 

I thought the same thing you did. Shouldn't matter but there is something it is changing in the response that is a world of difference. I don't know what it is or how to explain it!
It almost feels like it is throwing fuel into the cylinders.

 

Well......your signature shows you've got a whole car full of warranty voiding mods, including a tune!!!!

Butt.....some of us don't want to void the warranty - which even just a tune is reported to do.

So.....to get better throttle response without tuning the car, the Sprint Booster may be your answer.

As I said in my earlier post, my 2005 Coupe and 2006 Z06 both had tunes, and the increased throttle response was the thing I liked best.

With my 2009 I didn't want to tune the car, so I got the Sprint Booster.

I went to a show a week ago and there was the Lexus LFA on display - beautiful car, but I don't think I'll be springing loose the $400K to get one!!!!

However, I got some literature about the car, and some of the specs on the engine are:

• 4.8 Liter V10
• Incredibly responsive design able to rev from idle to its 9000 RPM redline in 0.6 seconds
• 552 hp at 8700 RPM and 354 ft-lb torque at 6800 RPM

Geez - my Vette engine stock was just barely coming off idle in 0.6 seconds, much less get anywhere near redline!!!

Now with the Sprint Booster it does a lot better!!!!!

Matter of fact, I run it in "Sport" mode because it does rev a little too fast in "Race".

You say you "don't get it", but why did you mod your car????

If it was so perfect stock then it wouldn't have needed anything done to it.

Bob

 

Bob you are right on! I have no mods to my car other than a K&N filter. I looked at a tune but like you said it voids the warranty and I wanted to keep it stock thus keeping my warranty. Like I said I don't know what that little black box does but it has a genie inside it.

 

Things will be a lot easier if you start by removing the plastic cover under the left side of the dash. It is held in by three trim plugs (I can't remember if there are three or four.) If you pry gently but firmly under the heads of the trim plugs, you can save the trim plugs. This will make for much easier access to the connector which is at the top of the pedal assembly.
There is a gray locking tab on the connector which you can release by pulling on it with your fingers. Once you've released the locking tab, take a mini screwdriver to press on the release tab. You should then be able to pull the connector off the assembly. Once you've accomplished this, just follow the instructions that come with the Sprint Booster. The whole procedure shouldn't take much more than ten minutes. If you encounter any problems, my e-mail address is eric@kinsco.com.
I have left my Sprint Booster in track mode which is indicated by the red LED.

 

Isn't all this thing does is accelerate the rate at which the throttle opens? If it opens quicker on the front end, then it's got to be slower on the other. Seems like a ridiculous mod, IMO, when you can simply move your foot quicker. Waste of $$$$. Guess it makes you think you're going faster.

 

Yes, essentially that's all it does.



No, the response from partial throttle is much better as well.

Your avatar shows some mods that probably required a tune. I'm sure part of the tune was throttle tip-in to give much better throttle response.

I guess you have forgotten how the stock throttle responds. It's not like a cable to the throttle blade - the electronic throttle response is programmed so that it doesn't react immediately. You can slam your foot to the floor but the revs only build as fast as they're programmed to build.

So.....does it make me feel faster?

No, but it makes my throttle respond more quickly without having a warranty voiding tune.

and, it makes a huge difference in heel and toe downshifts on the track if you do such things. I struggled with my car's lazy accelerator response for years until HP tuners came out with the fix.
