My question about the unit is what can it Really do? The throttle pedal is connected to a potentiometer which can only be read by the ECU as a analog value. So what values does the thing send to improve throttle response? A full throttle signal at half depression? Half throttle when the pedal is just touched? Someone should hook one up to a meter and see.
With an electronic throttle body, the percentage you push the pedal is not a 1:1 relationship (or at least, more than likely is not) with the percentage the TB opens.

This basically hijacks the TPS voltage and manipulates it to a different value on the applied pedal position table. Basically if the car associated 10% throttle pedal applied with .5 volts, with this installed the computer would instead see .7 volts and the computer would tink you're actually pushing the pedal down 15%, 20%... Its a piggyback.

I wave machines that you need to calibrate voltage on to give max psi. Is there something like that in this ie a "pedal calibration" where you mat the throttle and hit set and the computer goes OK whatever I'm seeing is max throttle? If so could you just press the throttle to 80% then hit set and trick the computer that way?

just thinking out loud...

I think the answer to your question is yes. I'll pull up an applied pedal position table when i get home later and screen shot it, and it'll make a lot more sense.

Does this widget just change the slope of the response curve (which I assume is linear--but maybe not) or does it produce a nonlinear response (for more butt dyno feel initially)?

If it's the former, won't the car simply reach full throttle with less pedal travel?

The answer is yes, but also "it depends."

So the pictures i have included are a stock throttle table for a mazdaspeed3 (just because the Cobb software is easier to see this), and one that i have adjusted similar to how this device would.
Even in the stock table, you can see it is not a 1:1 relationship between the applied pedal position (top number in white) and the actual throttle opening (bottom in green / red), but that's neither here nor there.

The first table is stock, and the second table is one i have increased the applied pedal position by 50%. So in the stock table, WOT was realistically at 100% applied pedal position as you can see. In the modified one however, you can see that really the throttle is fully open at 80% applied pedal position.

So, comparing the two throttle tables, the modified table makes the car feel like you are pushing the throttle further than you actually are, which gives the impression of better response. This is a very useful trick i use for big turbo cars i tune to try to eliminate the sense of "lag" in daily driving. It doesnt realistically improve performance, just makes the car feel more peppy, which i suppose can serve a purpose.

So, the thing is, i am not sure if this provides a linear change, or a percentage change. If it is a linear change like "increase all values by 20," then it wouldn't change the slope (for the sake of answering your question). If however it does a percentage change, like "increase every value by 20%," then yes the slope would in fact change. In either case however, it cant really change the overall shape of the curve, just manipulate the values globally.

Thanks, Volt--very informative. My suspicion was that it would cause one to reach WOT at less pedal travel, with a plateau effect (e.g. from 80% pedal travel/position onwards in your second picture).

A little bit of a gimmick, but potentially a useful one for the sluggishness one might feel for the majority of everyday driving.

Not sure if it's worth $300, though.

I had a rental once (don't remember what) where the throttle was real touchy...it is a trick mfrs will do to give you a feeling of power. I didn't like it but assume you would get used to it.

PEDAL COMMANDER

I just got the pedal commander pc-18 for my 2014 mustang V6 Auto and I wanted to give a review.
There is so much throttle delay in the stock vehicle...and with this device, its virtually gone! My pony takes off like a bat outta hell. When I need a quick boost...it's there!
This add-on has 4 modes to play with and multiple settings(levels) within each mode. I haven't used the highest setting yet since what I felt somewhere in the mid-range was more than enough for me.
It sure is fun. The long throttle delay is history. The thing to watch out for is the tranny temp gauge. I noticed the temp climb from 180 to well over 200 within half a minute. The accelerator responds much quicker now.
For anyone interested in buying this, have fun but use it wisely and cautiously.
I'm told it won't void your warranty but since it's a plug and play-I'd remove it prior to service or tuck it out of sight so as not to arouse suspicions.

I just ordered the Pedal commander for my 2016 GT Automatic. i want to see how it works with the Paddle shifter. I should have mine in the mail sometimes next week. i will give my feedback then, but i wanna say thanks to the positive reviews on this forum for this is the reason i got this one. The Mustang GT Auto for sure has some Noticeable throttle Delay. so i'm hoping this will improve everything...my vehicle is completely stock with the exception of a K&N Drop in filter

i actually got it and i absolutely love it...i am in no need of a Tune now and it doesn't void Warranty....My GT is totally Fun now and the throttle response and the different settings to play with makes it an interesting and enjoyable car to drive now. There was quite a bit of Throttle Delay and the Pedal Commander really impressed me...No bad reviews..All the Vids on YT are nothing but positive and fun feedback...IT's a simple way to get that instant throttle response that a tune would do but a tune Voids Warranty unless you get the Ford Power pak tune and have a ford dealership install...Good thing about the Pedal Commander is it's only $299 and you can get a discount. i paid $265 and i'm totally happy with it...No regrets and it's for sure worth it...

I bought this for $83 during the Black Friday sale on AM and it works! I drive my car year round so I need the ability to change the reponse on the fly. I can change the throttle response from my phone in less than a minute and that includes getting my phone out, opening the app, connecting to the controller, making the change(s) and then putting my phone away. You can change it at a stop sign or light, or even while driving (don’t use your phone while driving ? ). Unlike a tune on this you can pick from 36 different throttle responses.

I have mine tucked away where you can’t see it but can still get to it if needed. I tried Sport +2 first and it was WAY too responsive. Less than half throttle was full throttle. I then tried Sport -2 and it was still too responsive. I finally landed on City with no modification and it feels great.

It does NOT add hp but unleashes the power you already have in a more powerful way. It does “feel” like it adds a good bit of hp though. I’m satisfied with it. Especially at the price I got it at.

While I heard the pedal commander works, not many of us have $300 lying around. I installed the maxx boost throttle controller on my 2018 Mustang. It was half the cost of pedal commander, does not add HP but drastically improves throttle response as well as being MUCH simpler to use than pedal commander. It is from the USA, while pedal commander is made in Turkey! It is also MUCH more cost effective than a tune. https://www.sawyertuning.com/?s=accelerator
