2015 F350 recalibration

I have a 15 F350 and changed from the stock 34" tires and went to 37" tires and installed the Speedo Calibrator. One thing to remember when entering tire info even if you look up the numbers in height. The stock tires are 34.1" vs the 36.54..you need to measure once the tires are installed on the truck and on level ground. My 37's once compressed are about 36.25 Entering this number got me closer to the real GPS on my phone vs running 2 mph slower at 75mph. Ill be using 35.75, to get it closer.

A Great Fix for Ford Calibration Issues

I have a 2015 Ford F350 that I changed the tire size on, went to a 295/75R20. The change actually affected my navigation to the point of being worthless. I'm told that Ford engineers designed the GPS to use dead-reckoning in conjunction with satellite, a change in tire size throws your location for a loop. This system not only put my MPH dead on, it also fixed my Nav. issues. I would also recommend leaving the data cable attached for easy future adjustments. Great product!

Great!

I have a 2015 Ford F350 Super Duty with 6" lift and 40x15.50r20 tires. My speedometer was not even close to being accurate. After installing the 730120 Speedometer Calibrator it is dead on. Hypertech's installation and programing instructions that come with the 730120 were very easy to follow and made the installation simple. Thanks Hypertech for a great product.

Bought larger tires and needed speedo adjust after getting cited by cop. His radar showed me 14 mph faster than speedo. Used the inline module. Easy install with direction. Now speedo reads correct
