2019 Tacoma speedo/odo calibration

Can the dealer do this?

What is the cost?

Am I holding my head right? For wheel size not regearing, right? Because wheel revolutions via ABS

 

Dealer cannot do this. Aftermarket parts only.

 

Parts?

 

You would need a hypertech speedometer calibrator. They run for about $230

 

Pretty sure they don't make one for 2019.

 

I almost never recommend rough country, but they sell this as well and I believe it's cheaper. It's the same thing and uses the same software to program it.

 

Yes. They do

 

Anyone have model number(s)? Thanks

 

I used rough country part 90043. I'd check to make sure it's good for the 2019s though.

 

Definitely no they don't.

Paul,



At the current time we do not yet have a tire corrector product completed for your vehicle application.

We do not have an estimated time frame for potential completion

I will add your info into our product request data base so you will be notified if and when we do have testing completed.



Thank You,

If you have a 2019-2020+ start bugging them! sales@hypertech.com


I guess there is NO way to correct the speedo/ODO? That's just stupid.

 

@OVTune mentioned he found code to do it in the ecu a while back but I don’t know what ever transpired with that. There was talk of being able to do custom tuning and tire size adjustments being an option

 

So it's like a smart dealer COULD do it if Toyota had instructions. Thanks!

 

I guess I misunderstood. U want it permanently changed.

 

No. OV can because he cracked the ECU. Dealers don't have that ability.

 

I might as well throw this out there. I have found that the speedo calibration is different than the odo calibration. As it stands now on my Taco with 31.7in dia tires (14/32in new tread depth), my speedo has a 2.0% to 2.5% error, while the odo has a 5.0% error when compared to GPS over a distance. That difference will stay proportional as the tire wears.

On that, with 2/32in of tread left (at the wear bars), there will be a 2.5% change. So, the speedo will read accurately with worn tires.

Fun stuff.

 

My dealer told me the COULD calibrate it. It would be 2 ship hrs...

 

Curious, what GPS was used? Also, why is your speedo off 2.0%-2.5%? It shouldn't be a range and if you've measured with a GPS, you should be able to say exactly what it's off.

 

You didn't really read what I wrote. They COULD if Toyota provided support.

 

What's this? Works on a 2019?
