Rough Country Speedometer Calibrator

The calibrater will not change/fix the cruise control numbers.

 

I'd call Hypertech and ask them when/if the 2019 will be supported. Their website still shows it only goes up to 2018.

 

For those with 2019 & 2020 Taco's looking for a this speedo/odo calibrator, looks like Hypertech recently updated Part #730123 to now be compatible.

 

interesting. I wonder if all the old inventory sitting around in inventory will be compatible.

 

I'm guessing there was no physical change since the part number didn't change. So I would think the initial software update you download when programming your unit for the first time will be all that's needed.

 

that’s my thoughts too. In that case I’m wondering if the rough country calibrator would then work. As it’s pretty much just a copy of the hyper tech.

It is a Hypertech.

 

That's what i thought. I ended up returning the one i purchased back in December. I never even tried it out in the truck... I just re ordered one and am gonna give it a shot. I did email both hypertech and roughcountry. Hypertech said it's just a simple firmware update that makes it compatible when you connect it to the software. Roughcountry said that their units is still not compatible with 2019/2020 trucks even though theres a review on their website of someone stating they are running one on a 2019 and it works great. I guess we shall see!

 

So I just installed the rough country speedometer calibrator on my 2019 Tacoma and can confirm it does indeed work. In fact, those of you with 2019’s or even 2018’s with adaptive CC should update your modules. It’s displaying the correct Set MPH where it displays the ACC Mph tiny up above the actual mph. When setting your tire size there is also now an option to select 2019/2020 Tacoma.

I left my usb cable attached after I mounted it so I could reprogram and was glad I did. First program I set stock tire size to my stock size that came with the truck 245/75/16 (sr5) and 32.9 for my new tires. Mph was slightly higher than gps mph. I re calibrated and entered 265/70/17 as stock size and 32.9 for new size and it’s now dead on! Super happy now!

 

So this product is complete bogus? I just bought one but am worried it won’t work since I’m OVtuned. Thoughts?

 

The in-line calibrator simply adjusts the data going to the instrument cluster so the speedo/odo/mpg etc show the correct numbers based off your input during initial setup. I don't see why OVtune would interfere.

 

What operating system does this need to work?

 

I have the hyper tech one with a 2020 and ovtuned, no issues.

 

I just purchased this and hope it works for my 2019. Thanks for the heads up!

 

been working nicely so far for me!

 

does the mpg read correctly as well?

 

Windows 7/8/10, no Mac.

 

Yes.

 

thank you!

 

not sure. I just went with the hyper tech one after this conversation. I also have OVTune. No issues.
