Where in Michigan can I get this done ??

 

I think the dealer can recalibrate the speedo for up to 31" tires on a ranger. For anything over that you need to get a SCT custom tuner. You can get the tuner through the vendors on this site.

 

Your screen name implies that you may have a 96 and an 03. Which speedo are you trying to correct? The method is different between the 2 years.

 

The dealership can do it, but man it is a long process. I know you can change gears on certain models. I heard there was a shop on 59 in Waterford that did but I haven't found a name yet.

 

What size tires are you running and what year is your truck?

 

What size tires are you running and what year is your trucK?

2003 would like to run 32's or 33's currently have stock 245/75/16. if I dont jump in tire size just going to go with 285/70/16 for now. (Stock Suspension)I put that about 3 miles an hour differance

I may drop down to 15 inch wheels for cost purposes.

 

you have 245s? i thought all fx4s came with 31's? maybe just the lvl II

 

245/75R16's are very close to the same diameter as "31" BFG AT's.

For 2003, a Ford dealer can calibrate the PCM for tires up to 31's but no larger. Beyond that, you'd need an inline speedo recal box or a flash tuner like an Xcalibrator.

 

Attempting to get a list of winter projects for the truck. I called several trans shops if I go w/33's but nobody is aware of any shops to recalibrate it. Seems like a tuner is the way go.

 

I had a crown vic w/4.10s once. Found two places. One was on woodward (they specialize in nothing but speedos). And another place was in Dearborn Heights.

The place on woodward.. it was roughly 5 miles north of 696 and on the east side of the road. Can't remember the name to save my life.

I'll try driving home that way.

 

I calibrated mine with the WDS when I worked for Ford. It took about 15 minutes to do. So if you're not going wild with tire size they can do it on a newer truck.

 

I don't remeber exactly.. but it's on the east side of woodward and a few miles north of 696. Just don't remember how far north it was. Shop has been there for quite some time and speedo correction is what they specialize in.
