Ive had this pedalmax on my mind for awhile.. after having my xpipe done the muffler guys discuss my new exhaust tone with me. Then I told them about the lack of low end grunt in the car. They said the customers in past had similar concerns and they told them exhaust isnt gonna give em more power, only sound. I said that sound is what I wanted from the xpipe . What they told me is that my car is detuned from the factory and the horsepowed ford claims is on the high end of the motor if achievable. Before I left they advised me to at some point to send the ecu to a tuning company. They claimed it was a low cost alternative to buying the tuners out there. Is it possible to just send the ecu out to be tuned and get satisfactory results?

Not sure if it'll help anyone, but here's a re-post of something I put on the UK forum. For me, the primary purpose of fitting the PedalMax was a comfort thing (to get a shorter travel on the throttle pedal) rather than as any kind of performance enhancement:

Fitting

Well, first off don't believe the 'it takes 5 mins to fit' BS! About an hour is more like it - and be prepared to get yourself in some weird and (to any casual observers) very amusing positions. I ended up with my head down by the pedals and one foot either side of the headrest, holding my phone under my chin as a torch! :D

It's not too difficult to connect the actual unit or adjustment knob, but it's getting the unit and wiring cable-tied neatly out of the way that takes the time.

I fitted the adjustment knob down by the OBD (I think) port. It's out of the way so the setting is not likely to be accidentally moved, but still reachable from the drivers seat. I fixed it on with self-adhesive velcro squares to ensure the whole installation can easily be removed without leaving any marks.

Test Drive

So after I'd fitted the PedalMax unit and adjustment switch and ensured it was working I went out for a little drive.

In summary, very impressed. I had the car in 'Normal' mode for most of the time, but also tried 'Sport+' and briefly 'Race'.

In 'Normal' with the adjustment switch at about 25-30% it behaved exactly as I wanted; the throttle pedal travel was shortened by just the amount I was looking for and the response was improved. I then upped the adjustment to about 60-70% and ...... S:censored:IT THE BED! .... it really steps up the response! It's like you're in 'Race' mode, but more! - really aggressive throttle response but with all the safety nets switched on. Very enjoyable :D. I didn't get to 100%, but I think it would be too much for the road.

As you step up through the drive modes the more you need to turn down the PedalMax or things just get too frantic (on the road anyway). It would be interesting to try it on a race track, I'd be curious to see if you needed it at all in 'Race' mode - if you switched it up to anything over 30% (in 'Race' mode) it may well just turn the throttle pedal into an 'on/off' switch! :eyebulge:

In summary a great little gadget that did exactly what I wanted it to do. The adjustment knob allows you to fine tune the throttle pedal travel to exactly what you want for the particular location/style you're driving in. In 'Normal' I now have the pedal travel I like - not absolutely 'go nuts' aggressive, but just shortened enough to make getting full throttle comfortable for me in my particular driving position - and with the adjustment switch you can turn the whole thing off if you want to. If you're having similar comfort issues I'd say it's worth investing in one.

Are you guys uninstalling your pedalmax before dealer servicing?

Do it, it's not worth it not to if you aren't tuned and are trying to preserve warranty

Agreed. A member with an EB had a bad experience when he didn't remove his.

I believe his issue was with the JMS piggyback (increases turbo psi relying on ecu for safety) not pedal max.

He had both attached, but even so they will void it all the same since you are modifying the throttle operation

I had the pedalmax on my manual GT and it wasnt bad but never on my 16 GT auto.

I think I'll stay factory stock with my 16 GT as I need my warranty 100% intact without question.

With that said, I don't see how they could deny your powertrain warranty for something that adds no actual performacne or touches your ecu (pedalmax I mean).

The good thing about the pedalmax is that they won't know it was ever there if you remove it before going. Same with an intake out even a catback. But once you have an issue and they've seen you modded or tuned, they can use it as an excuse.

My dealership was complaining about the fact that I didn't have the stock wormgear clamps on my intake even though the ones I was using were way nicer stainless ones when I traded my Ecoboost in. They have no problem getting petty

Wormgear clamps!!! That really is petty.

You have to unhook your battery for the pedalmax install. Some have had cel's from whatever reason(impropper install?). The ecu also learns the throttle calibration. I'd imagine the ecu stores all that info for the dealer to potentially see and use against you potentially?

They can tell that the battery was disconnected (it's either due to a code or because the key cycle counter resets). But there are a lot of reasons why someone would disconnect the battery so I don't think that's a problem.
