VF Tuner 3UR Support - Development Tools

Hey I figured out that issue you were having on the 3D RPM v Throttle MAF Multiplier table (usually all set to 1.0) but it multiplies the MAF, the issue you were trying to add fuel in at higher load and the ECU ignored it.
I know why, and have found the controls that allow this table to be active full-time, which it's not stock.




Also I sent out some more Flex fuel converted SC tunes
vF Tuner update release expected by monday (includes support for new ecus)

 

@OVTune, is it safe to use the previous Flash Tool to flash a .p5f calibration after having used the current vF Tuner (earlier version) to flash a .vfc calibration? I'm just looking to tinker around with one of the previous calibrations that has the first version of Gear Lock while waiting for the (most recent version) vF Tuner issues to get worked out with my particular ECU version YWF63. Thanks!

 

Yes it is safe

 

I'm trying to purchase the KIT and the TUNE Pack.
The TUNE PACK link doesn't work and I can NOT find it on the VF Tuner site..

Can someone point me in the right direction please?

 

It looks like @OVTune has pulled the Tundra tune packs from the site. Unfortunately it looks like you won't be able to purchase the tune pack at this time.

 

Awe Man that sucks! I had it in my "cart" ready to pull the trigger but was waiting on my dealer to give me the thumbs up..
I finally got my dealer to install the Supercharger and allow me to bring my own tune..

@OVTune any insight a to when the TUNE Pack will be available for purchase?

 

Temporarily down as we are about to put up a new version of vF Tuner with additional ECUs

 

Thanks for the info.
Any idea when it’ll be back up?

 

Hey guys, I have a 18 5.7 CM that is basically stock and I don't plan on doing much to it. I don't tow often. I've been trying to read through this thread but was wondering if there is any benefit to either performance of MPG for someone like me.

Thanks for any advice.

 

No ETA at this time. Sorry. Supporting new ECU versions can be very difficult, and we have enough Tundra Dev to do right now. We thought we had all the IDs and now we have 3 more new IDs..

I am looking for someone to hire to work specificaly on our Tundra R/D

 

@OVTune For those of us that don't have the tire size option on our tune, can we adjust the "gear size differential 2" parameter to correct for larger tires?

What do we adjust to make the torque converter stay locked under heavier throttle?

 

@OVTune And while your attention is here for the moment . Is the older Flash Tool capable of flashing the newer .vft/.vfc calibrations?

 

No, doing that won't affect tire size. We are adding in the tire size tables.

The gear size diff table is if you have 5.29s, or 4.88s etc.


on our forum we will be releasing some calibration guides here very soon, basics on the tables, controls, setting up a file for a SC, etc

 

VFT yes, VFC no

 

Copy, thanks!

 

Woop woop!

vFT ver 1.2.9.9.4 is out!

 

What was added/changed? Thanks

 

VF VERSION 1.2.9.9.4 RELEASED
vF Tuner 1.2.9.9.4 Release Information:
- 07-17 Tundra Updated support (0CL43, others)
- Map updates - several ECUs
- Pro Tuner - Map updates
- Gen2 ECU Recovery flash mode (in case of ECU brick)
- Clear DTC
- Logger speed update (OBD CAN)
- Other useful changes

 

Unfortunately, no tire size map for my ecu: 0CM21

 

Ya, I see the Date modified is 3/5/2021. So...patience...

 

tire size maps not included yet. This update had a much needed recovery mode for folks, along with getting some other IDs in.
the file itself wont modify when we release more tables

 

Fixed it for you.

(Relax, I'm kidding around. As a fellow IT guy I know you guys are busting your butts. I'll wait patiently.)

 

new version of vF Tuner includes 0CL43, along with some other fixes. We are going to start ramping up production of tune packs now.

Also, we will be releasing a version of vF tuner really soon that includes Gen1 ECU Recovery tool so that in case you have a bad flash you can recover the ECU. It is not 100% effective though, due to the nature of these ECUs but works 95% of the time.


Edit*
we will make sure to include tire size

Wyndded, I've solved your issue as well and will email you regarding that

 

Hopefully I will get to try tune pack before my truck will be picked up by its new owner next week! Otherwise I’ve waisted 6$$

 

Ver. 1.2.9.9.5 is out

 

Tune packs out? Thanks

 

My truck was flashed with the dap tune years ago and id like to upgrade it with this one. Is it possible to save the dap file with the software and revert back or will it be lost? I did not get the handheld tuner as this was flashed in person with his laptop.

 

Unfortunately not without the handheld. I still have my handheld and I flashed back the stock tune before I flashed with OV tune. You probably won't even miss the DAP once the OV tune is loaded.
