Tacoma - OVTUNE - VFTUNER - Update Info and Original Development

Two part queation for you guys and @OVTune: if I decide to sell my Tacoma, would it be advisable to leave the tune (1.04) on the truck but keep the hardware to either sell or, question 2, if I decide to purchase a 2016 or newer 4runner can I use it for future tuning? Hope that makes sense. No issues with the tune or Tacoma but realizing I'm more of an SUV guy.

 

I wouldn't be worried...

 

I'm not I'm curious what he meant, I'd be surprised if people still like the old stuff (like 1.02) over right now

 

Like the old saying you can't fix stupid, I'm wondering if my truck has an existing issue that is bring down overall performance.

Can I use the kit to see if misfires or other issues are occurring with my truck?

 

I think he just trolling

 

Hell, I'm curious. And I am also curious as to the long term effects on the drivetrain with the tune. What's your opinion Mat? Do you think there could be any negative effects such as premature transmission wear?

 

There might have been some other "premature" actions after installing the tune.

 

They should have a warning with the tune. “Warning: reccomended to carry tissue on hand after tune install.”

 

I'd be shocked... the new stuff is light years ahead. But you know me, I was elated with the improvements of Stock to 1.01b way back when... lol.

 

Mat's the expert, I'm just a customer... but, I do have an opinion.

1. Transmission temps I'm seeing are nearly the exact same as I had stock. Never higher than I saw stock in any way.
2. Wear, who knows until the long haul has taken hold but damn for my truck specifically all that delayed engagement of the torque converter equated to the truck doing nothing until I was revving high then it would "SLAM" into gear with a jerk. Shifts were very rough and choppy. Now they are so smooth and predictable and I never, ever feel anything jarring or forced with this transmission...

I guess many of us will find out in a few years but based on the things I can measure with scanners or feel as a driver.... really doubt it.

Now as far as the broader drivetrain, depends on how you drive it I suppose. If you tune for 91 octane and drive your truck like a race car of course you're likely to cause some premature wear. To what extent, who knows with these newer setups? That would be true stock as well if you WOT every time you took off and rode the highway at 75mph in S3

Edit: And he does have probably close to 500 trucks tuned now and many of us have clocked >10k miles so far. Haven't seen a single engine or transmission failure from the lot and you KNOW how TW is...if someone did, we'd know about it

 

Exactly. All stock engine safety features are still in the ECU.

This is why I really like ECU flashes rather than piggy backs.

 

I’d surmise that even a conservative 2 inch Bilstein lift and some bigger wheels and tires would be way more wear and tear than the tune

 

Hey guys, so I finally got the PCM flash info from Matt and am going to install the tune in about an hour. I really, really do not want to browse through this thread so I'll ask here: anything specific I should do before/during install that will achieve an easier process or a more optimal install?

 

Just to confirm the last update was 1.04 for the ECU only correct? There was nothing to flash for the TCU. We’re still using the 1.03 TCU file.

 

Correct

 

Toyota has seen and analyzed my 3.5L tune.
they inquired about me being able to support them via software next year with their new engine in the camry for some endurance racing.

If anything, it's helping the truck last longer.

 

That some serious testament to your skills.. KUDOS for the great work!!

 

Anymore info ? Im intrigued :-o

 

Roger. Just was curious.

 

We need more info.

I wonder if them seeing and analyzing will come up bad for you. Like they’ll just make it a dealer update to the ECU.

I just can not believe toyota wouldn’t develop the stock ECU to be better.
