Tacoma - OVTUNE - VFTUNER - Update Info and Original Development

Figured it out and got it flashed. I took it for a drive and it feels so much nicer I uploaded the 33" file for my 285/75/16 to fix the speedo and I love the power balance now. Will have to see how mpg improves!

 

It doesn't fix the speedo...

 

Oops, guess I misunderstood. 285/75/16 is about as close to 33” as I can get without being 33” Should I stay on this file or go to the stock one?

 

The tunes can't change speedo, they are just meant for shift point tuning. You have 33's stay with the 33 tune. I was just letting you know they don't adjust speedo.

 

Thanks. Anything yet that is able to correct the speedo on a 2020? My previous F150 had a tuner that allowed me to change the tire size so I guess I figured this was the same kind of thing (on top of the tune.)

 

You have to install a speedometer calibrator. Google Hypertech speedometer calibrator for Tacoma. I have one installed to fix mine. They work well

 

Rough country also makes one. Uses hypertech software and firmware. About half the price.

 

Neither the Hypertech (or the Rough Country version) support the 2019 or 2020 model years yet. Word has it that they may be updating the device around the beginning of June.

 

That’s what I had read and I’ll keep my fingers crossed!!!

 

do I need to update to see this ECU in the flash manager?

 

Is it possible to have the Base 87 33 tune w/ the 2.0 or is the 2.0 already included in the 33 tune? Sorry if that’s a stupid question, haven’t looked at this thread in months.

 

I havent really been following this thread, except to complain.
I know final has not been released, but for 04B04 people, is the 4/19 test release the latest file?

 

So, while patiently waiting for 2.0, went ahead with a little pre 2.0 preparedness (rolled around time for a oil change and within range of the rest of the fluids). Complete transmission drain and fill, diffs, and transfer case. Now, just waiting cause i'm still on the 19800 beta from awhile back.

 

Did you do the 3-4qt drain on the trans or the full 11-12 or whatever it is?

 

I do the full (10.7 quarts) although I typically try to overfill cold and then do my level off.

 

Yes.

 

Thanks

 

I know, i know..but can anyone send me 04B04+2.0+Final+Test/04B04+2.0+Base+91+OL.p5f
I accidentally downloaded 31-33 version, but my calculations now tell me that my LT265/70/16 is 30.6in

 

sent you a link

 

Thank you
