Tacoma - OVTUNE - VFTUNER - Update Info and Original Development

Been there since last sunday

 

I'll give that a try again.
But last time it was not going above 5th gear on a flat surface at 55mph. Which kind of kill economy for me.

HOWEVER - I only did ~ 30miles like this so might need to give it a longer try.

Will do that this morning and let it like that for a longer try.

Regarding English, no text driving but sometimes I don't find the right words to properly explain what I'm trying to say

Thanks to all

 

Future development later this year. I believe it's explained further down on page 1.

 

This sounds like the rather aggressive tip-in on the Performance tunes. As someone already mentioned, flash 87 or 91 Base and you should be good. You could also try what I'm doing - 87 Base with ECT engaged. It's very nice indeed.

 

Dongle user here. With the “shudder”. I’ve been running 1.05 87 base for a while, after trying 1.05 87 performance (tip-in was too much).

Flashed to 1.05.1 91 base this morning. Shudder is gone, and the truck runs better all the way around.

Thank you Mat @OVTune

 

Possibly there for developer access, sorta like a test server for video games. Only a few would have approved access (by computer ID in this situation) but everyone can see the option.

 

Do majority of the people 91 octane vs 87 octane

 

Have to tried to drag the truck in 6th or 5
th gear on slight incline with RPM below 1500 (45-50 mph)?
1.05.1 87 base shudder is more pronounced vs 1.05

 

Nope. At 45-50, I throw on cruise control and let it do it’s thing.

 

I run 93 base because 93 is relatively cheap where I live. I tested 91 and 93 tunes and prefer 93. I put a note by my gas cap just in case anyone else is driving/filling my truck.

 

So, how do you know if shudder is gone?
CC will never put the truck in this condition..

 

I went with Base 87 today (without LV AT reset) and after 120miles done it doest shift on 6th on highway.
On flat road with cruise at 68mph it stay in 5th at around 2000rpm

 

Because I’ve driven it on a flat road to 50-55mph and there’s no shudder.

 

If it shifted to 6th at 68mph you'd be lugging and probably get less MPG.

 

Yah, trying to see if a regear or this would be good.

 

Believe it or not but , I flashed 91 performance for the second time today after trying out the base tunes and the tip in is milder for some reason .Maybe i'm lucky .

 

I know that driving on flats is fine, but do you ever experienced the shudder that OVT made changes to?
Chages were made to Torque converter sequencing

 

The shudder isn’t specific to inclines, it occurs on flat roads as well. I’m satisfied that it’s gone, at least on my truck.

 

I have been on 1.05 87 base for about 5000 miles now, and before that i was on 1.05 87 perf but tip in was a little annoying so i switched. Anyways, when i first put 1.05 87 base on the truck ran 99.9% perfect, but now after about 5k miles its shifting strange and seems to somehow be reverting back to some of its old crappy habits. There is however still some improvement vs stock that remains. I am really at a loss as the WTF is going on here. Has anyone else noticed this? How is the tune holding up for you after 5k? Not faulting OVTune at all, just curious wtf is going on the would cause the truck to start acting super crappy again even after the tune. The thing I have noticed after owning this truck since late 2015 is that the truck drives amazing after you clear all learning, both stock and now i guess with OVtune. After a few thousand miles, no matter what, it starts back to its old crap shifting, lugging, huge RPM spikes, shutter, all that stuff. My opinion is that there is something majorly wrong with the learning this truck does and how this "learning" affects drivability. Thoughts?

 

Did this ever happen?
