Where did you get your speedometer recalibrations done?

I don't see why not, nothing really changed from 14 to 15.

 

Keep meaning to do this. I have a pile of more fun things to install.

 

I just ordered one, will install and calibrate and get back to you all and let you know if it worked.

 

Damn got my Hypertec speedo calibrator and it's for a tundra, I hate Amazon sometimes.
Grrr...
So the one Hypertech has for tacoma only goes to 2014, but I'm going to try it anyway.
Now I have to return this, get my money back and then find a place that has one.

 

I've pretty much decided to keep the speedometer as is. It's been long enough so I automatically know what speed I'm actually going.

 

but how are you figuring your mileage?

 

I used a gps to find out the true mileage and then figured the math. Worked out that I need to multiply whats on the odo * .9 and divide by the gallons dumped in.

 

thanks for that math tip. gonna check it.

 

BTW I'm wondering how you came up with the .9 multiplier?

I'd like to find mine as well here's my tire conversion link:

Using the GPS and mile markers on the highway I found out that for every 1 mile I was actually driving my odometer would record 1.1 miles. So basically my mileage on the odometer is about 10% overstated. Multiply by .9 to get it back to being more accurate.

 

I can't imagine that anybody that puts a 6" lift and 35" tires on a 4cyl Tacoma has any concern for MPGs. I know I wouldn't.

 

I just use my brain. When I'm going 60mph, I know I'm actually going 64. So, I just round up to 65 to be safe. Going 65, I'm actually going almost 70, etc. The slower I go, the smaller the difference gets. I just go a little under when I see a cop or speed trap. I don't even think twice about it anymore, it's just an automatic calculation. Plus it shows less actual miles on my truck in the long run, saving a little bit of resale value

 

AT, yes?

 

at 65 im actually doin 67 based on GPS. not a big enough differance for me to worry about so it doesnt bother me. i have 33" with a 2.5" lift. it must have been off from the factory and putting the tires on it actually brought it closer to the actual speed...weird.

 

Going from a ~31 to a ~33 would be about a 3.5% difference which is why you would see the jump in mph from 65 to 67. Why would you think the factory was off? Unless you have a manual trans then your speedo was way off.

 

from passed experiances with other vehicles when i switched from a 31" to a 33" tire id usually see roughly a 5mph differance at 65mph. it is an automatic. maybe the other vehicles were off and this one is dead nuts on..lol.

 

Yes, AT, but that wouldn't matter.

 

It would if you had an MT and were regeared since the speed is calculated in different areas for an AT versus MT.

 

Hypertech FTW. I have one and it's been great.
