Tacoma - OVTUNE - VFTUNER - Update Info and Original Development

Did you do it through Flash Manager > ToyFlash?

If so, I see Clear DTC & Reset LV....what is Reset AT?

 

Reset AT deletes auto trans learned behaviour. It will then re-learn your driving style with the new tune.

 

Sorry for long delay guys, we are finally getting all these out

 

Yes. Those are the functions. I am an MT, so I don't have experience with the AT Reset.

 

So you guys let the truck idle for 5-10 mins after you do a flash/reset AT/LV ?

 

Yes. I just set a timer and chill.

 

I’ve got a 19 AT and 1.05.1. I still feel a small shutter here and there.

 

Yes. In my opinion, it's completely reasonable.

 

I get random strangeness that MAY be what you describe as "torque converter shutter," but I'm just waiting to see what 2.0 feels like before switching from 1.05. I did not try 1.05.1, as I'm still not entirely sure what it changes, and I don't want to give up all of the "learning" my truck has done on 1.05 to date. For the most part, I'm happy with 1.05 and dismiss all the strangeness as a result of broken factory programming that still resides in the system -- hence, my eagerness for 2.0 where a lot more that legacy code is getting replaced.

I honestly still have no idea whether or not the lag and other strangeness I sometimes experience is what you're calling "shutter"...

 

The TC emits a vibration when on no matter what. The “shudder” feels like the truck is slightly starving for fuel

 

19 AT,
stock - no noticeable shutter
1.05 87 base - noticeable.
1.05 91 base - not noticeable
1.05.1 87 base - not noticeable

 

I'm in the same boat...my 18 is on 1.05 87 base, It with anytime ECT on has become my favorite tune so far, and I'm kinda skeert to change because I don't want it to lose the values it has now. I have read all the talk about "shudder" and still not sure exactly what is being described. I've heard mention of going over rumble strips, starving for fuel, bucking and jerking, and so forth....those all all so far over the spectrum, it's difficult to know if MY truck has an issue. 2 things I know for sure, under HARD acceleration, not flooring it, like merging onto the interstate in faast traffic, and trying to keep pace, or passing a slow vehicle, where it downshifts, and is climbing the RPM's, my truck starts to surge, I can feel it losing power and coming back, over and over until it shifts out. And the 2nd thing is the dead pedal, when cruising at 60-65, I can literally press the pedal to 3/4 of the travel, and it will only gain 3-5 mph, then violently downshift to 3rd gear and haul A**....I have kinda accepted both as just a give and take, some parts of the tune are a huge asset, and some aren't. I feel it's def more than less. But I'm def not sure if that surging under hard acceleration is the "rumble"?? Most say its at 40-50mph, but is that on the initial launch??? @OVTune

 

I have that exact same behavior at 60-65 mph with my 2019 AT on the 1.05 93-Performance tune.

 

Also have this 87 performance 1.05.1.

 

I’ve got a 2019 AT. Still waiting for registration email from OvTune. Will report back once I flash the tune. On stock tune, definitely have the dead gas pedal issue sometimes. No “rumble strip” issue in the 2100 miles I’ve put on the truck. @OVTune send that code please!

 

My truck is a 2018 it had the shudder from the day I got it. It's hardly noticeable on 1.05.1 now. I'm hoping 2.0 resolves the issue. But if not its 98% better than it was.

 

I have a May 2019 built TRD OR and it has all the issues described: the TC jerk/surge, dead pedal 0-75% on the highway, then downshift to 3 or 4 and RPM through the roof, zero power where it's needed in the RPM band, etc. So Toyota has not fixed any issues. On a positive note, the truck does feel better now on the second tank of gas. I assume she IS learning, but 2.0 can't get here soon enough.

 

Thank you @OVTune Matt for the registry!! Registration and flash was effortless with the provided instruction. Flashed 87 base since I still have a half tank of 87 gas. Drove around 40 miles with the tune and the shifting is definitely improved. I’m impressed. Once I burn through this gas, I’ll probably fill up with 91 and flash the 91 perf tune. Then the fun should begin! Thanks again Matt!

 

Okay dongle dudes. How the hell do you do this? I have the file downloaded. Everything ready to go. What do I do with these three files? Install all of them? One of them? It's been a while since I've done this. Also at the top there is no interface to choose from. Does that matter? All I could find in the FAQ was dongless fellows. Which I am not.



Edit: Resized way too big image.

 

You only need one file. You can select either of the top 2 - p5 can or can bus
