I did this FREE mod over 3 years ago. Same thing but free.
Looks really good, noticed this is for an 05-09 model is the gas pedal the same in the 11-14's?

It looks like it helps the throttle lag but the PedalMAX supposedly "Increases low and mid-range horsepower and torque." I certainly can feel it on mine. I'm not sure if that's just the result of no lag, or it's doing something else.

Anyway, I'm not good with small electronic parts, but someone with an '11-'14 should try it.

How is that if it doesn't interact with the ECU?

My guess as to how PedalMax works (and this is just my guess/illustration- I could be completely incorrect) is a simple "recurve" of the throttle signal. From what I can tell looking at the module on the accelerator, the "fly-by-wire" throttle is like a dimmer switch (except you push the pedal instead of turning a ****).

I think PedalMax probably "resets the curve" something like the graph below. Basically, they've taken the dimmer and weighted it so the first portion of the dial has more effect than it used to. At least that's the way it feels to me- you push the accelerator 1/2" and it sends the same signal that 1" used to. Probably more complicated than that- but that would explain most of the effect.

Reason i asked earlier if anybody with a 3.7 '13 auto had tried it was cause im wondering if it made much of a difference. Apparently the '13 auto's especially the 3.7, are notoriously difficult to make anybetter regarding response/transmission..

Or at least thats my case lol

I actually pulled the trigger and purchased this for my 2014 3.7 (decided to hold off on new gears and tune until my warranty ends). Installed the unit last night. Installation was very easy...took about 15 minutes or so (the hardest part was trying to secure the unit with the zip ties above the pedal, haha). I have a only driven the car a few miles (hope to test it further today), but I could definitely feel a difference in the throttle response. I know this doesn't add any HP or torque, but my car just feels "lighter" overall. Not sure if it's worth the asking price, but like I said, hope to do some more testing the weekend

Keep us posted. I hope this is one of my winter purchases.

Varilux is indeed correct. This device goes between your throttle position sensor and the ECU itself.

I would advise against this device strongly. If unknown logic occurs in the device, it could cause a vehicle runaway condition. As the ECU sees this as driver input and does not consider other safety factors.

You can achieve the exact same performance as this device by getting a quality tune. If you don't believe me, I will be more than happy to send out a SCT tune to anyone that has this device for comparison at no charge.

As a previous OEM engineer, I would NOT buy this. Solely because of the safety factor.

Just my .02 cents

Matt raises an interesting point. For what its worth, I already had a Ford Racing ProCal tune on my '14 GT- and I still noticed an improvement with the PedalMax.

End of the day, I still notice an improvement with the PedalMax- even with a prior installed tune. I'm not sure why Ford built a "lag" into the factory throttle position sensor, but for whatever reason they did. PedalMax seems to resolve the lag- even after applying the Ford Racing tune. Perhaps other tunes are able to program away the throttle lag... once I am past my factory warranty- perhaps I'll find out (although I'm hoping the point will become moot- because if I keep my '14 that long I'll probably be installing a turbo- or super-charger).

My next mod is the BBK cold air intake (hoping the slightly improved intake flow will work well with the Ford Racing tune- but primarily looking for the "bling" of the CAI ).

You're assumptions are correct. The ProCal does not have aggressive Drive By Wire changes.

Using a custom tuner such as SCT or Diablo with a quality calibration is much much better.

Cheers,

I've really tried to feel for the throttle lag, and my 2014 just does not have it. The slightest touch of the pedal blips the RPMs.

I only notice it while accelerating. I wouldn't call it throttle lag as much as torque management. It feels like the ECU is not opening the throttle as much as the pedal is telling it to under high load, and doesn't really open completely until you're fairly high in the RPM band.

I also verified this with my datalog after tuning (not that there's any question about it's existence...just sayin'). Pre tune the throttle was NOT always doing what the pedal was telling it to, post tune they are significantly more in line with each other.

I noticed the same thing with my factory tuned 2014 auto. Not so much of a lag when blipping the throttle. I notice it more when i'm cruising and give it 1/2-3/4 throttle to command a downshift. There's definitely some torque management going on there where not all ponies are being let out of the stable.

I'm assuming this is just your opinion, and you have no evidence of this actually occurring.

Correct, I have not seen or heard of this happening. Knowing how it works, I am saying it could lead to an unsafe condition. The PCM and this device share no logical link, just analog input.

PS. I have nothing to gain or lose from sharing my opinion on this product.

Ditto. I have a steeda tune on my 2014 and as much as I tried I cant feel any throttle lag. That pedalmax seems to do the same thing that the Si Drive did in my Sti. Just changes throttle input relative to pedal position.

The owner of JMS is no rookie and I'm sure plenty of testing went into this product before it was released to the public.

I am sure a ton of testing went into the unit.

However, it does not change the fact of how it works, and its vulnerabilities.

That's your opinion.
