2016 OVTune Tacoma 3.5L Manual Transmission / Engine ECU Reflash

Can anyone do me a solid and download all available tunes in FM for 04B90 (2020 MT) including stock, or post up a link where I can download them.

for the life of me I can’t get FM to work properly. Keep getting the download error. I’ve uninstalled it and re downloaded FM several times following Tonereds instructions.

EDIT- apparently all tunes have been pulled for the time being. If someone has 2020 MT stock tune saved, I’d love to have it! Please pm me and I’ll send you my email.

thanks all!

 

I would bet the entire can of monster that I'm currently holding that the surge may have to do with changing fuels for winter blends across the country.

 

I’ve got around 10k kms on 2.0 and it’s surged almost from day 1. It’s worse under certain conditions (seems kinda random) that I haven’t been able to figure out yet.

 

I believe Mat ( OVTune ) took it down ....... not sure why ....... this was last week. Others have tried.

I believe they were listed here: https://www.ovtuned.com/blogs/news/tacoma-2-0-final-auto-release

I don't see them now .... it might of the change over to the vForest software ...(IDK )

 

I think you might lose that bet?

I'm a bit too lazy to prove it though since I'm feeling other changes that are bound to happen. But, I could do an LV reset and report the same behavior 1mo from now. Baby butt smooth right after settling, then this rearing its head again. The tune edits seem to soften it though?

 

I think I did lose that bet so I owe someone a can of monster. It was worth a shot though considering there are hundreds of different fuel blends being run as the seasons change. I was just wondering if it had to do with some of the octane learning dealing with different additives. This is just my conjecture while I'm at work waiting on a truck

 

Oh yeah. Way too many blends nationwide. If I were king . . .


On my side, OL has been friggin' great from the first try. When 2.0 SFOB Prem dropped, I flashed it with 87 in the tank. Three tanks later I went with 92 for about 15 tanks. Then, flashed 04B14 SFOB Prem and ran 92 for the rest of the summer. Now, switched to 87 for the winter. I think I heard one set of pings in about 10,000mi. There was zero difference that I could tell other than a more mellow throttle now on 87.

 

Can confirm this to be true. Just re-flashed SFOB Prem and reset LV's etc. Truck drives without the surging. Feels a decent bit smoother. But, once the tune is settled in, I'm sure it will reappear.

 

It’s a shame @OVTune hasnt picked up an MT taco to work these things out.

 

Funny.... I don't see you two going through thousands of coding tables for multiple vehicles and developing tunes.... It's a shame really.

 

Easy dude, I’m not bashing Ovtune. I quite enjoy the tune, but it’s far from perfect and likely will never be.

In response to your above statement - I also haven’t branded and developed a product that advertised as fixing most of the tacomas drivability issues. I knew the product had quirks when I purchased it. I’m sure 100% of “tuners” would agree that’s it’s almost impossible to effectively tune a vehicle that you don’t have regular access to for R&D purpose.

 

You do know he's like a two-man operation with tunes for about 10 different vehicles right?

 

One man right now.

 

We made vF Tuner to allow anyone to make their tune however they like. I don't know what you are talking about with "excuses." We have developed excellent tunes for the MT trucks.

I'm not making excuses. MT tunes are finished. If you want it further customized, use VF Tuner.

We have handed the tacoma community literally all of our development in an easy to use software, free or super cheap for most.

 

Actually, click the blue "i" button and several tables have explanations or helpful hints.
On top of that many of the tables are based on super basic EFI logic.

We have also converted things to make it simpler.
We also patched the MT tune files so you can control throttle from 1 table..

A lot has gone into what we have made for you guys. And considering I'm 1 guy providing it all, I am very very happy with what I've produced in the time that I've been working on it.

Rather than just complain, use the VF thread and the software to your advantage. Everyone is helping eachother.

 

I just purchased the flash to VF upgrade (7619) and hopefully can improve 2.0 with the info/tweeks already on this forum.

I still have yet to see an explanation for the low rpm “surging” that most of us are experiencing.

 

More info would be helpful.
Tuned? Stock?
What rpm?
Gear dependent?
Catalogs of it?
Does it happen specifically between 1000 and 2000 rpm?

 

It’s similar to what’s been explain on TW many times over by Ovtuned folks. I wasn’t going to bug you directly, as it was something I learned to live with and seemed to be a quirk of the tune. From what I’ve read, there wasn’t a “fix” posted, although it could be diminished using VF.

Im: 04B90 2.0 SFOB 91. Been tuned for around 10,000kms, ADM, CORE shifter

Low RPM (1000-3000)most noticeable in 2nd but can feel it occasionally in higher gears. I drive my truck fairly conservatively and keep the revs low most of the time.
In 2nd it feels like there is a torque limitation that “turns off” between 1500-1800 allowing full power. The surging typically originates at that point. I also feel very mild surging slightly higher (between 2-3k) in higher gears (3-4).

In my experience it’s most prominent during moderate acceleration.

Occasionally and randomly the surging (not just a single surge, but waves of them) will be really bad. I haven’t figured out what condition makes it worse (ie cold engine, faster clutch dump etc).

FWIW it’s not associate to a crappy gear change/mismatched rpms.

Re-flashing/resetting LVs seems to temporarily fix the issue while the tune is in the learning stage. Once the tune is settled in the surging reappears/steadily gets worse as the tune learns.

I haven’t done any logging as it was my impression that you’d sorta wiped your hands of figuring out these small quirks and moved to VF to allow the individual solution for each veh/environment to be figured out by a local tuner.

 

Okay I think I know what this is, but did not know until recently.

A lot of stuff we have learned came recently from all the forced induction development.

Most likely it is from the various injection mode changes (port, direct, and what ratio of each).
Originally we thought the ECU only uses the main split ratio table.
Recently (this year) we learned a lot more.
And there are certain ratio changes that occur at various RPM points all the way until 3500 RPM where the ECU switches it's injection mode entirely.

i would need data to confirm, but I would not be surprised if it's the reason.

These tables will soon be available in vF Tuner. Don't quote me but I think there is 80 different settings, rpm break points and such.

While modifying these during development I would experience noticeable surge under 2000 RPM, and again after 2600 RPM.

But to be clear this surging happens at light / moderate throttle, not full throttle.
