VF Tuner 3UR Support - Development Tools

Cant wait to see how it stacks up on the dyno against the dap.

 

Does the tune improve how quickly the transmission manually shifts in Sequential mode? Stock the shifts are super slow to respond.

 

That's a good question!

 

He can mod your tune for the shift points your desire. He has done it for me.

 

Shift points or manual shift change speed? I understand them as two different things.

 

Yes that is correct ideally you want to lock it in 4th and maintain a target rpm for a specific amount of time. That’s challenge with our trucks. When I had my SC Sequoia dyno’d with the HP tune that was the problem that they were running into same as Matt. They couldn’t keep it in fourth gear to do the tune because it would downshift about 3500 rpm’s. Keith says that there’s a trick to it that he was able to do to keep it in fourth gear running the RPMs necessary to get a good tune. Most tuners are familiar with LS engines they actually have a gear select and can lock the preferred gear in, not available on the Toyota’s unfortunately

 

That annoys the crap out of me in the S mode of shifting, why give you the option of shifting if it does not shift when you make the shift.

 

I can go into better detail on how the transmission and shifting works if you guys really want to know.
As far as changing shift speed (how fast it shifts?) definitely tune-able.

 

2018+ Only Tundra ECU patch notes:
Phase 2.

Through more testing and code work we have enhanced our 2018 + ECU tables. Exclusive to OVTune, if you have a 2018 Tundra (and upcoming for 2019!!) we have made big changes to the ECU.
(due to size limits on older ECUs, some of these features are only available to 2018s) With the 2018+ ECU having more than 4x as much free space available, it will get even more features in the future.
This will all be available soon via our blog post on it too.
These features are finished, coded, and now ready to send out.
Map size increase is 150% more resolution than stock!

- Ignition BIG MAP - updated versions of our original patch

- valve timing BIG MAP - updated versions of our original patch


Supercharged
- Supercharged Fueling Mod - Fuel Map - similar to older ECU patch

 

Cool!

Guess time to upgrade to a newer model.

 

I probably don't realize what I'm asking or any implications of it, but I'll ask anyway.

Is it possible to purchase one of these newer ecu's for an older model? And if so, would there be any benefit of doing that to a truck like mine?

Again, im not sure it would even work or be worth it. I just plan on keeping my truck, even if I buy a newer one some day.

 

Won't work


Also, if there is anyone with a 2018 and our flash kit interested in testing a patch for us, please let me know!
MAF - Delete - with our Airflow compensated Alpha - N fuel model (which will soon be converted to speed density, pressure based, on Supercharged trucks)

 

Thank goodness... I just knew my wallet was about to get lighter.

 

If you had to guess, how much better will the newer trucks perform with that much extra space?

 

in for 2019 when available

 

Depends on how many features we develop. Plenty of room in the ECU to develop a LOT, just depends on what features we want to make, and what features the community is looking for.

 

I think this would be a good read, but only after we have the opportunity to experience what you've accomplished to date (for comparison).

 

Pretty AMP'd on all these updates.

Do you have a run down on order#'s that will be fulfilled soon?

Order#4815 here.

 

At the moment unfortunately it is not going by order number it is going by ECU version

 

Logical....

 

2018 Supercharged cal finished and sent out.

edit **
forgot to add for 2018 CALs,
Worlds first true 3D Fuel table for the Tundra.
(load based, for Superchargers)

Based on Engine speed and engine load -

VS STOCK TABLE:

 

As he just replied..both

 

I bet this was my tune Ran great!

 

Good gravy... Edited for the worst memory in history.

 

lol what.

 

Good gravy... Edited for the worst memory in history.

 

stock shift points? or literally "stock tune" in S mode.. as in stock VVT.. stock fuel.. stock ignition.. etc (*extremely* unlikely)

 

Oops... Talking out of my ass. You are right, it was only the transmission that was stock in S mode...

Carry on folks, nothing to see here.

Totally embarrassed.

 

Hahaha! *pointing finger*

Just kidding! I appreciate that you had the mindfulness to think and ask about this to give those of us that also have a DAP tune flashed a reminder and refresher as to the what we're comparing our trucks performance and behavior to once the OV tunes are available to more owners.

 

Everyone good here?
