Quicker throttle response

[18psi]

all this bickering and at the end of the day no one even knows how the pedal booster actually achieves it's results.

1) if it's by simply amplifying the signal, and thus commanding the car to provide 20% throttle when 10% is requested, then it is stupid and a waste of money (in my opinion)
2) if it's by keeping the full range of the pedal sweep and OEM commanded torque tables, but simply shortening the time it takes the car to get from pedal input to throttle position output, then it is great and worth getting.

something tells me it's the former and not the latter, because the latter would most likely need to be achieved by a full tune of many parameters in the car's ECU, and not just an amplification of the pedal signal. but if someone (perhaps the people that engineered it?) can prove that it's the latter, I will gladly buy one.

These cars have terrible throttle response at low rpm/low throttle conditions. When I command 10% throttle, I want 10% immediately, not 20% throttle with a half-second delay

I think you are misunderstanding what systems such as Peddlemax are capable of...and are misusing the term "lag". These systems do nothing more but intercept the stock input signal and alter it to provide a different output signal. They aren't controlling lag, but rather are controlling the signal output. Their goal is to allow less pedal travel provide more throttle blade travel. This simply reduces modulation, providing more of a on/off style throttle body response.

The lag you are talking about is not lag at all, but rather a programmed output to allow a smoother pedal modulation.

Some people like the light-switch response these systems provide, but they do absolutely nothing for performance. Quite frankly, you would have a difficult time measuring the time delta between stock and aftermarket when you slam both to the floor. These systems are a personal preference item only. For many (like myself), we feel the money would be better spent elsewhere. For others, it's money well spent to give the "feel" of more performance. To each their own.

I don't agree with this. Back in the day when i had my 2012 camaro, some people on the camaro5 forum did some testing using the pedal max at the drag strip. If i remember right, the car with the pedalmax finished couple of tents of seconds faster than without it. My guess is the shifts were done with a manual and without power shifting. Auto's or powershifters probably wont notice any difference but just the feeling. We are talking about less than 0.1 seconds going WOT and staying there till the end of the runway.

Disagree you may, but unless you're vehicle is defective...or if you have the foot reflex of a sloth, the pedalmax can do nothing to improve you're 1/4 mile. .2 seconds equates to a 20 hp bump in performance. The placebo effect can be strong.

If you dont agree with that then you must at least have some sort of theory on what this maxpedal does. Can you please explain it a little bit?

Can you please post a link about this camaro that finished .2 quicker with boosterpedal?

The fact of the matter is that any given throttle position up to about 3/4 throttle the car will have more HP. Of course no more HP at full throttle. I have the pedalmax and love it for daily driving where I seldom go full throttle. You can try and retrain your foot to just go farther but I never could.

Any difference between pedalmax and pedalcommander? or are they the same thing?

Im well aware of what these do. Im not against them.. theyre like bigger throttle bodies.. more air.. more response but really just like opening the throttle more and ending up with less resolution (75% throttle = stock tb at 100% throttle therefor reducing resolution by 25% vs stock). But in the end.. I have a steeda tune.. didnt feel a thing different. Throttle response still sucks. I may give one of these a try

I doubt anyone had any gains in the quarter mile. I used one of these on my 2010 Camaro SS and it made no difference on level 3, 5, and 9. It won't help because the majority of time spent in the quarter mile is at WOT. Canyon carving and circle track may have some differences since you'll be on and off throttle. But not at WOT in a straight line. But I'm not taking anything away from this product.

Great thread.

There are two opposing arguments that really aren't arguing the same thing here. One group says "don't say it doesn't do anything" while the other says "what it does is pointless" (I'm in this group).

The problem with virtually all DBW cars is that, as someone pointed out earlier, that the ECU controls when and how much the throttle body actually opens and that, usually, you never really get full throttle until a predetermined minimum rpm. Further, and most frustrating and what the OP was actually referring to- there is a long delay (I'd say a full second at lower RPMs) between slamming your foot and the ECU responding with the fully permissible throttle opening. This is the "lag" that we speak of and there is no way a simp,e multiplier will affect that.

A linear throttle is FAR more precise and acute and offers vastly more control than a multiplier which, essentially, reduces resolution and said precision. Further, these devises actually create massive dead spots in the throttle past the artificial "100%" point.

My other car has this built in and it's a complete gimmick. No thanks. What I want is instant response "at the motor" without altering the factory multiplier. If I go WOT I want it NOW.

Does this device do that?

WHat I would want is one mode... throttle matching the pedal input. Is there a mode that will give accurate throttle opening as in 50% throttle = 50% throttle body open? I have a tough time rev matching perfectly in the mustang and I hate having to really stab the throttle because I know it wont rev fast enough otherwise

Stock regular mode is 1:1 you already have it. Only time it's not is when tcs or esc is active or torque output is higher than the limit which won't happen on a stock or lightly modded car.

I have it and it was worth the investment. I have a n auto with 3.15 rear. I put the shifter in S whenever I drive the car around town. In D the trans would shift to soon and lug the engine. The throttle response was terrible unless in S. In S mode, around town, it gets old with the downshifting with Roush AB and h pipe. I found Pedal Commander by mistake using Google to search for Pedalmax. I called and talked to them and after doing research it was cheaper, had more adjustability and could be switched to other US based vehicles if I ever sold the mustang. Well after playing with it. My car feels like I added 100hp when taking off. The gas pedal was very touchy. So much I found myself burning rubber taking off normal. I had to back it down to city mode -1. I tried sport mode and it was too much for daily driving. In each mode it can be programmed down or up 4 settings. You can do this while driving and feel/hear the difference. I dive in D around town now and no more hunting/lugging in between gears. Not sure why it works. Don't care. It was worth a try with their money back guarantee. I am not ready to tune my car with3k miles and messing with my warranty. Dealers around here are not mod friendly. Neither one. If I would have listened to all the naysayers who claim it is worthless and doesn't work(push pedal harder) I would have missed out on a great product. Fortunately I hate to follow the crowd and when somebody tells me it can't be done I will prove them wrong. To all the people commenting on why it doesn't work PLEASE STOP! If you don't want it turn the page. This is a review from someone who has it and believes the average guy will love it. I don't race my car. I do like going from stop light to stop light feeling like I have 400 hp. Before this product I felt like my car had about 200hp. My 08 Tahoe felt like it was faster. With PC it feels like a 400 hp car when taking off. I have owned a few supercharged vettes,blown bbc and a twin turbo997. I now power. Please once again. I DON'T care about racing!!!! I like the stress relief it gives me when I hit the gas and the car throws you back into your seat as it breaks the tires loose. Try it. It will cost you nothing if you don't like it. But you will. Believe me. :cheers:

It's not about what I want, it's about what your product actually does.

Please address my questions above.

You're sure making it sound like it's all about what you want...
