Tacoma - OVTUNE - VFTUNER - Update Info and Original Development

I get what he gets with 32’s and 4.88’s

 

Weird, I have the same thing but 32” 255’s and avg 16-21 without my trailer

 

Which 255 and rating?

 

255/75/17
SL
Hankook Dynapro RF11

 

Ah.....damn 17's
Definitely more selection in 17 than 16.

 

I have both. My 16’s have SL Falken AT3’s and they do about the same. Width makes a difference at highways speeds

 

So I ran stock size tires with 2.0 premium thx. Loved it all around. Throttle response is great drives great.
Got my new 255 85 16 cooper st maxx tires on and loaded the 33 thx premium tune. Man I've never felt the truck drive this smooth before. Shift points I've noticed a good difference..truck honestly doesn't feel like a slug like I used to. The downshifts are really nice too with the shift points matching better. Also offroading in 4low is way better to control. Running the performance map was horrible for 4low. I was getting whip lash all to fook. So far its going great. Truck holds 6th gear even time to time which I never really saw either on beta tunes and my 33s.

 

im running 265 75 16 on the stock/thx, and im tempted to try the 33 tune, except it drives so nice i kinda dont want to touch it ha.
the 33 tune just has the shift points dragged out a bit doesnt it?

 

I ran the 33_premium tune with my stock 265/70’s and it ran good, I’m trying the 35 tune now. Only have a few miles on it but it runs just as good. Haven’t tried it out on the highway yet. Shift points on city driving are about 2000rpm which is nice because it doesn’t feel bogged down in city driving. I don’t have a lot of weight on my truck either and it runs good on both tunes.

 

Ok guys i've been having this hesitation/stumble when trying to accelerate from stop. Does anyone else have this issue? I'm on 2.0 final 04B04 stock thx. This happened on non thx and on stock also. I've done some searching and found a TSB 0062-18 for this stumble but can't find cuw file. Has Mat not added this tsb to the tune?

 

If your ECU is 04B04, then you have the latest available for a 2017. There were a couple of different TSB's, but the ECU update for all of them was 04B04.
For reference, Mat cannot include the ECU updates in the tune files because the ECU updates change data files and software programming. Mat's tune files only change data files.

 

I'm on 04B04 and this happened to me on the THX tune. I went to the stock NON-THX and its been flawless.

 

Oh okay thanks for clearing that up. So has anyone else had this problem? It’s scary making a turn when trying to beat traffic. Not safe

 

really? That’s what I had first and had it. Then went back to stock and still had it. Monday I flashed thx and still does it

 

If you flashed to stock and still had the issue it shouldn't be the tune.

 

That’s what came to mind at first, but I’ve never noticed this issue before. When this started was the time I first reset AT values. And I know it shifts rough after that and will settle after few miles. But the hesitation is there and noticeable.

 

Have done everything on the directions so far and I’m now stuck. I have the computer hooked up to the OB port on the trucks ECU, and once I hit the flash tool then the screen looks a little different than directions (the highlighted interface) and once I hit identify no calibrations are showing. Anyone have some knowledge to shed? Will be emailing them as well.

 

Make sure you installed the drivers, then use the pull down menu under your mouse in your picture to select the tactrix option.

 

It's not showing that the Tractrix is present. Is it plugged in to a USB-2 (not 3) port? did you install the drivers?

 

I just installed "2.0 Final Premium Stock" on Wednesday, and I've only driven it about 12 miles so far. Updated from the "3rd Beta Release 16012" from August 2019, and I did not clear values. I haven't had any issues so far with this new final. And yes, I always take my time before jumping into any new release
