I just purchased a speed recalibrator on ebay, and the guy said it was new, and it isn't...No big deal except it has no instructions. Its made by ford racing and is for the 2001 and up model mustang...Does anybody know how to use this? Where to plug it in? What to do? Or if some can direct me on where to find the actual instructions that would be greatly appreciated.

 

ok i could be very wrong but if you look under the dash on the driver side near the console there is a obd2 plug see if thats where it plugs in.

 

Speedo calibrators are relatively simple to install, but at the same time are a total pain in the a$$. I've got instructions lying around here somewhere for mine, if I can find 'em I'll share.

 

Should've went w/ a Speedcal. Took 15 minutes to install and is DEAD on...

 

Same with my speedcal...

 

well I'm looking for responses from people who have the ford racing one I have, not responses telling me what I should have bought

 

Well, is it anything like the Dallas mustang speedcal... I've never seen one or heard of it before..

 

Me either. I never knew Ford ever had one...

 

yeah, its on their racing parts site. I don't know what the dallas one is like...I figured they all worked pretty much the same...What is the process you go through with these other speed calibrators? Where do you plug them in?

 

there is a series of dip switches that you have to set according to what your stock gears were, and what you put in.

This may not help you with that, but this explains how to install it.
