will the Phoenix recalibrate my speedo?

[Nuge]

I just put in a PHP Phoenix 6 pos. chip in my 2002 Excursion with the 7.3L diesel. When filling out the online order form, I entered the stock tire size, and the current size with my 4" lifted set-up (35s). I was under the impression that my speedo would be calibrated as such by PHP. Will this chip fix the speedo error on my truck??? Thanks

Sorry, the speedometer is driven off your ABS module and cannot be calibrated via Phoenix Chip. The reason you were asked to enter your tire size it because this can effect shift speeds.

There are ways to calibrate your speedometer, but check out the Superlift Tru-Speed.

Bringing this back from the dead. I am running 37's now and am having 4.88 gears thrown in. Truck originally was on 31.5's with 4.10 gears.

My wifes friends husband is a ford mechanic and I am trying to see if he will recalibrate the speedo with their computer.

Do I risk anything with the PCM being updates etc and compatability with my 6 pos chip?

Or should I just wait to find some One with an AE?

Nope, just make sure the chip is out before the re-flash.

Out out? Or on the stock setting out?

In your glove box out.
