My 991 TTS Cab just didn't react as quickly as my 2011 997 TTS Cab. I just got it corrected! There is a thing out called a Pedal Box made by a German Company and Distributed by Shoreline Motoring of Huntington Beach. It took them about 45 minutes to install and what a difference. It is now as responsive as my 997 was.

 

Can you elaborate on what it is exactly?

 

It is an electric control of the throttle. Check out pedalbox.com

 

Sounds like "sprintbooster" which is sworn by many R8 guys as well. It just makes the accelerator hyper-responsive to even the slightest of input.

 

Exactly and on my R8 the sprintbooster is everything the owners claim it to be. I did the GIAC tune on my 991TT-S which pulled the "mushiness" from the throttle. Im not sure if if I need sprint booster as well now... its 299 for the TT though.

 

What part couldn't be accomplished with an ecu throttle remap?

What I dislike about these things, is that it is essentially putting an untrusted element inline in a throttle by wire system... So in theory if it failed it could go WOT on you... Or just die... It becomes the weak link...

Is it simple enough that it won't happen? Don't know but I think it uses power so there is a risk.. Consider if you blow the fuse it's powered off of you have a dead car...

I still remember the AUDI frenzy in the 80s on the first throttle by wire systems,, Personally I'd look for an ecu flash that accomplishes the same thing without adding hardware..

 

Thats a very interesting point indeed. I have not come across any threads in which people who have used such devices have experienced any failures, but I supposed that some type of malfunction is in the realm of possibility.

 

FYI. The Pedal Box is completely integrated into the factory gas pedal connections with OEM connectors and has no other connections.

 

I suspect they are simple enough they are pretty reliable and I assume if their failure mode would be dead not WOT. And to be fair I've not heard of anyone using these have a problem.

But there are other aspects of something like this.. have they tested in different environmental conditions (extreme heat or cold etc).. Are they potentially susceptible to things like RF from things like cell phones, Wifi, radar etc.. What if your battery / alternator is putting out a higher or lower than normal voltage.

Probably no issue, but I'm kinda paranoid as in the aircraft industry we have rigorous testing we do for electronics equipment to determine how it performs with environmental and electrical environments. And the most rigorous testing is done for things for things like flight controls and throttles. especially fly by wire stuff.

And when we run these test sometimes we find weird stuff happens (which is the point of running the tests)..

For fly by wire systems, they often use double or triple redundancy with and have cross checks between them just so that failures can be detected.

I believe the automotive industry has a certain level of structured testing they do for critical systems (i.e ABS and things like that) but doubt aftermarket stuff does anything other than what they want....

But to be realistic this isn't exactly as critical as the flight controls on a B787.. But then again if my Porsche suddenly went WOT in traffic it wouldn't be a pretty outcome... Sorta becomes like the out of control Prius situations from a few years ago.. (although it is questionable if that was the driver or the car..)..
