vF Tuning for Manual Transmission 3rd Gens

I renamed the Torque Limit / Air Load Control thread and tossed up my edits to the 04B04 Example maps in that thread. I am planning to flash it later today.

 

Guys i wanted to show how a tiny edit makes a huge difference with the primary table.

I have the file i have been running and i love it, its smooth, except first gear. First gear is downright touchy on the throttle.

I tried many changes to tone it down and i realized that maybe im pushing the pedal down further than i think.

Well, i was. I made a small edit to my primary and it made a huge difference, added a little numbing to the throttle, and a small step somewhere in the pedal range around 2500 rpm or so.

Any way, here is an example picture of one map (the top) which is very touchy, and the other map (bottom) which is spongy.

Im gonna split the difference and try to find a happy medium.

Let me know how it feels. I went back to my other one as yours had a bit of a thud on and off throttle. Thought it was in my head, but verified when moving back to my other one and it went away.

 

That was a small change. Just a couple percent in that area?

I am looking forward to adding this in. But, I learned my lesson about one change at a time.



That is really interesting about the On / Off issue. It was certainly the problem with the first edit for me. The second edit has been great. I hate to step away from it, but the @OVTune maps look so good, esp being the same.

Once I get a couple drives in, I will see what the numerical differences are between them.

 

after doing one round of 800-2000 smoothing as per Mat, 1st is less peaky for me, but interestingly i find the touchiness part of how i feel it being direct. i have to dance the throttle still, and that's the directness in response, and 92ehatch you mentioned numb being the opposite extreme. but if you can get a balance, that is worth trying. i love the shit out of my truck and how it drives now after 3+ years of work, but it's a big handful and requires full focus to drive well. sometimes it's a bit much, the margin for smooth & performance is very narrow.

 

it was a 7% change with some interpolation.

i fixed the on/off issue with the factory values strategically placed within the first gear table and some interpolation to smooth it out. There is a HUGE difference between Matts first gear table and the Toyota first gear table. Once I found what I liked I started smoothing with the primary table, just to get rid of some aggressiveness it had too early in the throttle range.

I have sent my file to two different people, im not sure if they have tried it yet. Im interested in feedback on it (different driving conditions etc) to see if there are any complaints elsewhere.

Most of this stuff with the throttle and responsiveness is going to vary so much between driving styles, its not a one size fits all

 

It is definitely hard, esp with what seems to be variability between Tacos as well.

I am not seeing 7% deltas between your map sections above?

I have only heard from you and one other person on the Air Load Control maps. I'm only batting 50% Hahaha!


It is pretty cool that we can tailor it once is the details and effects are known. I think we are close to that? I would be great to get a blessing on some of this, esp with respect to anything that might be in the danger zone.

 

you are right, its not 7%, its 7% as a base of the selection area, then interpolated. The interpolation was done in small sections to smooth it out. so the end result, random numbers

EDIT: actually it was a multiplication on 93% to start (so not exactly a drop of 7%)

then the above was true

 

Whew! I thought I was losing it more than usual.

Those random numbers are tough for me to deal with. That is why in the Air Load Control spreadsheet I just posted, you can see the values that I did simple averages on. I hope this will come in handy if I goof it up or for others that want to see the actual changes.

 

It’s the fault bytes. Set them both to 0

Whoa! Great nugget!

Calling @M1Awolf ?

 

Also guys, if you multiply cells, remember, doing a positive cell by over 100% will add to the value

IE: 100 x 105% = 100x1.05 will add 5% = 105

but if you do it to a negative value, it will decrease. not add (since the negative value will grow and be more negative)

IE: -100 x 105% = -100 x 1.05 will subtract 5% = -105

if you want to drop positive values you can multiply by less than 100%

IE: 100 x 95% = 95 (decreases)

and -100x95% = -95 (increases)

 

At least the rules of math still work in the odd reality of the 3rd Gen ECU.

 

aha! thanks man.

 

Thought about this.

Your air load smoothing introduced something into my tune that i didn't like, but i only loaded your air load table into my modified tune. My throttle tables are completely different from yours.

Anyone reading these posts should be aware that putting multiple people values in different maps will not produce the same results unless you use all of that person's values.

 

That is the truth! And, is a reason that I am not a fan of posting full tunes. Picking and choosing maps get to the personalization that someone wants.

 

I wish OVT had a team a few devs that could help him create a cherry-picking system where some newbie can go select specific bits and drag and drop them to their tune. Almost like how lego mindstorms used to be programmed back in the day lol.

 

I am really happy with the new tune. It was responsive, yet mellow? Mello Yello came to mind and might just be my name for this tune. @OVTune 's Air Load Control maps are the shit. Smoothing them just a bit more is goodness for me.


Also, I am not 100% sure on the High Idle change yet. It was a bit better, but the revs were still higher than the my setting. I'm wondering if there is another map for the MTs or some other interacting map. I know more with more cold starts.

 

which tune are you referring to? last week or this week? lol

 

The latest that I flashed yesterday. It is has all my current edits, but I swapped in the slightly smoothed versions of @OVTune 's 04B04 Example maps and set all cold start values to 900rpm.

So in total it is:

-- Baseline: 04B14 SFOB Prem with 87 octane
-- 1st and Reverse Torque Limits at 100% in all modes
-- CC set a 10kph - Does not seem to work.
-- Speed Limiter set at 312kph
-- ALC is smoothed 04B04 Example
-- Both available Cold Start maps set at 900rpm​

 

a bit of a side question but would like to keep it here if you don't mind..

now that I'm building my tune, and i have one exported version with multiple edits (i know, i will start iterations now), is there a way to swap in the 04B04 ALC maps w/o rebuilding from the original export? so i can keep and not redo my AGM edits, etc?
