Tire size: Speedometer results question
#16
#17
I failed to mention my 20 wheels have 35's on them and they wouldn't/couldn't calibrate it. Obviously, much bigger than stock. I really didn't care, the truck was not at the dealership for that, but the tech thought he's be nice and calibrate the PCM, but found out he couldn't. And, with the Edge and GPS, I know how fast I'm going.
it can be done, just takes some work.
have you guys noticed that the edge makes your tranny slip or anything? it did on my powerstroke before i beefed up the tranny. how much horsepower gain did you notice? and can you still run 87 octane gas?
(sorry Op for getting off topic)

they can recalibrate 35's. the guy who helped me do mine recalibrated his own ( he has 35's)

My tranny has been fine. I put 31,000 on the Edge, then got the Gryphon custom tunes and have 21,000 on them. No problems at all. On the Edge, you use 87 on the towing tune and the sfift tue. You use 91 or 93 on the performance tune. For the Gryphon custom tune, you can get it progarmmed however you want it. I have an 87 Performance tune and a 93 Performance tune. If you are considering an Edge, I highly reccomend going for the Gryphon. Same hardware, same canned tunes, but comes with the custom tunes that are much better.

Before I put on larger tires, I figured out how close the Edge and speedo were to the GPS. (Edge was dead on and the speedo read 1 MPH less, by the way.) Once I put on larger tires, I reprogrammed the Edge with the tire size from the Edge manual. It still wasn't quite on, so I kept adjusting it, lowering it 10-25 mm each time until the Edge and Garmin matched up again. I know I was overly **** about it, but that's how I am.

Does the odometer actually run up faster, or did Ford make the odometer slow down to compensate for the discrepancy in the speedo?
#26
I know that on the mechanical, the odometer and speedometer are using the same gear. On the computerized, I do not know. I just assumed they used the same sensor. If someone knows for sure, maybe they will speak up.

like if it's 10 percent too fast 88 would actually be 80, but 77 would actually be 70 ( i may have reversed that)
i duno, im terrible at math, but yea, percentage stays the same throughout, numbers don't.
i probably just confused you all even more. haha
this calls for the new smily we got
