OVT vF Map Edit - Acceleration - Primary Throttle Efficiency Target (PTET)

Hey, Folks.

This thread is for the Primary Throttle Efficiency Target (PTET) and was previously called the Primary Throttle Torque Target (PTTT)

The main vF thread is here for reference:
https://www.tacomaworld.com/threads/vf-tuner-for-the-3-5l-tacoma.662948/
All details below are posted there and more. The intent of this thread is for info, instructions, and discussion about this one feature (Linear Throttle) for tune editing.

Credit to @Boxerocks for getting this going. His post is here:

This map is attached in the V2 spreadsheet.

Following those instructions, I made this edit to the Acceleration - Primary Throttle Efficiency Target:

Note: There are two cell errors in the 11% and 17% columns. Thanks for pointing that out @nxcess ! Those are fixed and flashed.

After a day of driving, it smoothed these values (highlight and hit CTRL +I ):


Smoothed Map (this map is included in the attached spreadsheet):


The 0.0% to 9.5% jump was a bit much for me.

V2 Editing Info:

-- Copy and Rename the Tune that you want to edit.
-- Open the Renamed Tune in vF with Unlock Credits
-- Find the Acceleration - Primary Throttle Torque Target map
-- With the mouse, highlight the 35.3% Accelerator column of values.
-- Hit CTRL + F to bring up a dialog and enter the value that you want.
-- In this case: 25.5
-- Select all values between the 35.3% and 100% columns and hit CTRL + I
-- Select all values between the 0.0% and 35.3% columns and hit CTRL + I
-- Close the Acceleration - Primary Throttle Efficiency Target map and Save.
-- Close the Tune and Save.
-- Flash up and enjoy!​

Spoiler: V1 Editing Info

-- Copy and Rename the Tune that you want to edit.
-- Open the Renamed Tune in vF with Unlock Credits
-- Find the Acceleration - Primary Throttle Torque Target map
-- With the mouse, highlight a single column of values.
-- Hit CTRL + F to bring up a dialog and enter the value that you want.
-- In this case:

For the 0.0% column, all values less than 0 were replaced with 0.
For the 9.5% column, all values less than 9.5 were replaced with 9.5.
For the 11% column, all values less than 11 were replaced with 11.
And on for all columns through 64.89%.​

-- For me, I then selected the first four columns as shown above and hit CTRL + I to smooth those values.
-- Close the Acceleration - Primary Throttle Efficiency Target map and Save.
-- Close the Tune and Save.
-- Flash up and enjoy!

vF Editing Functions:

-- As far as I know, there is no Undo / Redo function.
-- To effectively Undo, just Close the Map that you don't like and Do Not hit Save. You can then reopen the unedited map.
-- To cut and paste, Select the cells that you want and Right Click / Copy.
-- CTRL + A / C / V works.
-- A Copied selection can be pasted into a spreadsheet for editing if you like and Pasted back into vF.​

Post up any questions!

Have a good one.

​

 

Good stuff. You should note that this map is only for MTs. AT throttle mapping is different.

 

I just finished editing a SFOB premium file with the Air Load table changes combined with the linear throttle mod you explain above.

So, the throttle was too twitchy?

I might skip right to the smoothing of the first 4 rows in that case (as long as it doesn't mess with low end response too much)

 

Thanks!

That is implied by the 04B14 SFOB map and my signature. Can you post up the AT version?

Yeah. It was a little much as the throttle is more sensitive with both edits. The smoothing has it feeling goood, except for mid RPMs in 1st gear. Nothing horrible and it might just be the tune settling or my relearning?

 

Good point, I'll try it without smoothing and see.

I prefer to "clean slate" the ECM after every new flash, just a preference. The truck acts retarded for a short while, but is usually cleared up enough to guage the changes made by about 20-25km.

Also, I was wondering about those negative torque values in the stock Primary Throttle map.. any ideas?
Something to do with smoothing out clunks and bumps in the driveline when we M/T guys are lifting and getting back into it?

 

Same here. I reset the DTCs and LVs after every flash just to get apple to apples comparos. I know a lot of folks don't do that, so I left it out. Considering the nature of the change, it might be necessary? Not sure though.


I was thinking about that also and was considering asking @OVTune . My guess would be that 87% is typically the max seen on the throttle plate, so negative values might be there to expand the range of the map? More granularity between -20 to +87 than 0 to +87? Better than changing the max value and hoarking up some other part of the tune.

The chance for linear feel was just too strong to pass up though.

 

I did this edit also and it's very nice. I find letting out the clutch is smoother after a shift now, because when I give it some throttle I know what to expect.

I have to smooth out the lower end also. It is ok in 2wd or 4hi, but little to sensitive in low range. Going to have to play with this some more. Good Stuff Gentlemen!!

 

Yes, 2Lo is. I am wondering if that will settle out or if I will adapt?

 

Please post snips of your altered maps!

I haven't flashed a throttle smoothing file yet, still working incrementally on the airload ones.. I have built a file that combines both though!

 

Also, if folks want to share, they can Select the entire map, Right Click Copy, and Paste it into a spreadsheet that can be attached to a post.

 

At the rate I'm going it will never get a chance to settle. I told myself I was going to go for a week before making more changes.....

 

Hahahaha! I said that about yesterday's attempt, but the improvement was real.

I do intend to give this one more miles, esp to gauge MPGs.

 

Thank you again Tony. I appreciate what you are doing.

 

You're welcome!

No problem at all. I am hoping that we can get a lot of patches in here.

 

Hey, Folks.

I updated the 1st Post with Stock and unedited 04B14 maps for reference.

 

-- Hit CTRL + H to bring up a dialog and enter the value that you want (This didn't work on my CPU - it was CTRL + F)

Hi guys,
I wanted to follow-up on Tonered's post about the Linear Throttle mod since I finally opened up some Maps in VFtuner and tried to edit them following your advice. I also edited the Throttle Management Map like Shellshock posted in the main VF Thread to 100 at the same time so I don't know exactly what is responsible for what - but I do like the responsiveness better than the Base 2.0 SFOB Premium 04b14 tune in every gear.

Thank you for posting up the details - I can see how this level of manipulation can get addicting. ​

 

Nice work.

I will confirm the CTRL + H / F thing on mine.

 

CTRL+F worked for me - too bad I read about that after manually changing all the fields

Hey... I have a question regarding both the Linear Accelerator Vf Mod and the Air Control Smoothing though. I made both mods this weekend and have not had a lot of time to run on the change and let it settle. I probably won’t until later this week.

My problem is under normal acceleration; things feel nice and smooth but I have have issues just driving around the neighborhood. Normally I would drive through our neighborhood at about 25mph in 2nd @ about 2500rpm. After these changes, this does not work well and I can’t hold a steady speed. The ride is a bit herky-jerky with very little accelerator input. Going up and down hills is a pretty harsh switch between accelerating or maintaining speed and engine braking. If I cruise in 4th it’s okay, but that just feels odd to me. I was curious if anyone had a feeling if I should play with the Accelerator or Air Control tables to see if I could get a little of the low speed/rpm/accelerator angle smoothness back. I assume my issues are related to the increased values in the Air Control Tables due to my smoothing, but I made too many changes all at once to be sure.

I figured that I might copy the upper left quadrant of another tune into mine to work out the issue, but I‘d like to have a good table to target for changes rather than doing too much trial and error.

Any thoughts?

 

Yes. I had that also. It was too much smoothing on the Air Control maps. See the updated 1st Post in that thread.

 

I attached my spreadsheet to the 1st Post.
