2 Very Random/Stupid Questions/Observations

[BIRDMAN]

1. Do the adjustable pedals, namely the gas pedal, have any effect on throttle response? Think about it, when you move the pedal all the way "up", there's about 4.5" from pedal to floor. When you move the pedal all the way down, there's about 3" pedal to floor. Since at any point of adjustment, there is a varying distance to the floor, does the throttle calibration change?


2. Speedometer readout beyond 60MPH. Next time you're on the highway going say, 75 mph. Look at your speedometer. The needle reads 75MPH from your point of view centered with the gauge cluster. Now move your head to the right so you're looking at the speedometer gauge straight on...it will appear to read 72MPH.

So the question is, in a world where 10 over the speed limit is probably not going to get you pulled over, and 13mph probably will...how is the speedometer calibrated? Is it calibrated to be accurate from the offset driver's view? Or is it most accurate straight on?

The good news is, the further to the right of the speedo you view, the slower it appears you're going after the 12 o'clock position (60mph). So, from your wife's point of view in the passenger's seat, it looks like you're going about 5-6 MPH slower than what you see from the driver's seat.

Great points. What IF, the world were really flat?

She still doesn't think you know where you're going, though.

"Use the NAV honey!"

(They don't tell you to buy a map anymore.)

Being that we have electronic throttle bodies, I don't thing the position of the pedal does anything for throttle response. It reads the same thing regardless of how far the pedal is from the floor. As far as the speedo goes, I recently found a radar station that cops put up and did a few passes to see if mine was close. The number it flashed matched what my speedo was reading so I'd have to say it's calibrated from the drivers point of view.

I would think the pedal stop moves with the pedal, is there even one?. Does the pedal even go all the way to the floor when you put the pedal to the metal?

Mine is accurate to within .50-.75mph on my GPS when looking straight forward.

Since I put 37's on, my speedo is all messed up anyways. When it says 70 mph, I am actually doing approx 75 according to GPS radar detector - so I just assume I'm roughly 5 over even at different speeds. No tickets yet.

Let's take acid and start a discussion about time dilation. I feel like we could cure cancer with these discussions.

 

[MajorAR]

and then there is always the Flux Capacitors, we need to ensure they are working too.

Well I will tell you this, my Raptor is much more responsive when I drive it barefoot over having my sneakers on. Explain me that!

1) the pedal electronics move with it, so it shouldn't change anything

2) in mine, straight on the gauge (not angled from your normal seating position) seems to match real world mph better. I measured with a GPS app I downloaded to my phone and used on level ground.

*After a 6 spd swap and tires size change in the GT I DL'd acouple apps to try to recalibrate the speedometer and wanted to see how accurate the then 3 month old Raptors speedo was..
