This is a very helpful piece of electronics. You can hook up two items to the one plug in your vehicle. I highly recommend this product for anyone wanted to hook two devices at once.

Rough country speedometer recalibrator
I bought this when I went to 275/60r20 which if anyone doesn’t know is a 33” inch tire it was a little difficult at first going to the website and downloading the tuner programmer but once that was done I plugged it in and probably took 30 minutes for all (I’m not very good with computers) once I plugged it into the obd port on my 2014 Silverado it was very simple

Good tool but...
This worked as it was supposed to. The only unclear thing is about the tire height. I called Rough Country and they told me to measure the tire with a tape measurer for the correct height instead of putting in the manufacturer's stated tire size(they didn't state that in the instructions provided). But over all good product and fixed my speedometer in about 10 minutes.

Did Not Work
I ordered this for my 2023 Ford F150, due to the 24 inch wheels and rear gear upgrade. Followed the Instructions and It did not work at all. Highly disappointed.

Works like a charm
Appears to adjust speed fine but the miles to empty/ fuel economy screen flashes occasionally now and pretty sure it didn't do that before adding the device

Easy to use, PC Required
Once I called Rough Country they explained that the unit needs to be calibrated as my unit could either be used for 2017-2020 eco boost or the 2015-2016 V8 which I have. It comes ready for the 3.5 eco boost out of the box. After plugging it in to my PC which is required it was able to select the correct programming and install on my truck was very easy. Make sure you measure the true diameter. My 37x12.5x20 tires measure 36inches. I used the 36 inch number and it matches my gps based speedometer.

RC Spedo Calibrator
It works at re-tuning your spedo to read correctly. A not frills unit, easy to use. I left the connection cable in place, coiled up under the dash.. It's a pain to get connected the first time so leave it. You'll want to reset to factory when going for service so the cable is ready. I wish there were more control options other then just spedo and odb error reads. But it does what it's suppose to do.
