vF Tuning for Manual Transmission 3rd Gens

I didn't, because i wasn't sure if that file was based off the 93 oct SFOB 2.0 b14 file. If i can confirm that tune has all the original 2.0 SFOB goodies on high octane, i'll happily make my AGM, throttle, and air edits to it!

 

And relating to the rev hang - i have an email back and forth from Mat stating he's working on adding those maps to VF, as @tonered said, they are not in there yet - this was 13 days ago so i just pinged him for an update.

 

With the TT kits getting shipped out and Rafael working on 2.0 AT Final, I think they are maxed out at the moment?

 

I agree. I just hope things don't slip and fall away like the AT 2.0
In all fairness, they are super busy. I'm just hoping they don't lose overall focus on their products

 

I think the AT guys can squarely blame Denso for the trouble there. The neat part is that Mat found the problem before the recall was announced.


Given some of these recent patch posts, I think it is exactly where they want this to go. Less BS from the goons and all the joy of deep dives into the code. We just need some more complete instructions about the changes and interactions, IMO.

 

not to side rail this thread, but i totally missed this. I assume what you're talking about is the fuel pump recall? How does that factor into 2.0 for AT's?

 

I think the pull is strong across the board. I think this tune was the SFOB 93 Octane Learning with some adjustments for the Rev Hang and maybe something for "airflow per gear".

I made some pretty strong changes to the "Acceleration - Primary Throttle Torque Target" table much like you identified earlier, but bumped some values in the higher rpm ranges.

 

i would THINK the rev hang tune he posted was based on SFOB 2.0, but i don't have any way of telling and i reallllly like how my truck drives right now I don't want to guess work it

 

Some of the 2019 goons were blaming OVT for their Tacos falling on their face when it ended up being some of the affected fuel pumps. Also on the TT PowerMax kits, he discovered that the fueling was uneven and the three mode LPFP was causing starvation issues during transitions. So, the 2.0 AT Full was throttled back until the recall issue was fully determined and the OVT fuel control kit was developed.

Nice! I can't wait to see the Compare function.

Take a look at @92ehatch 's Primary Thottle maps that he posted there. I plan to either try his or one of my own that is similar.

 

and what did you experience from that? did you note those changes somewhere? I've probably seen it, but y'know..

 

pfew what a relief, i didn’t know that, i thought you’d have to custom everything. I guess now i just need to know what to get to be able to do it. On the website he’s got the software, software+ flash cable, and a Tacoma 3.5L tune pack which states that it’s an add on but it includes the OV tuned tune files. Does that mean I’d have to buy two products to get the original files? I miss it when it was just Pay 800 and you get everything you need. This whole a la cart business makes it tough for the lay man like me

 

I thought I was very happy but I'm actually very confused at this point.

The listing for the test file said "modified: (superfob) + throttle hang / airflow per gear" and since the file name was "04B14+2.0+Rev+Hang+Clutch+Hang.vft"; I thought it was a 2.0 tune. @OVTune had at one point stated that all 2.0 tunes used a single gear table for the M/T. But now I'm reading where some folks indicate this was a stock 04B14 tune with a few changes for Rev Hang.

Maybe the upcoming Compare function will help me figure things out, but I know there is stuff in each tune that is "hidden" from vF Tuner too.

I might just have to stop posting for a bit as I might be talking outta my butt and adding to the confusion

 

I think you have it correct? OVT knows best. About the only struggle there is that he will often edit posts a long time afterward.

The most important part is that it seems to be working for you without that issues you were having.

 

@tonered i have your smoothing with my throttle edit going in for testing this afternoon.

I'm hanging up the dfco and rev hang tests as there are obviously some decel maps and we only have access to accel maps

 

Sweet! I'm looking forward to your thoughts.

I am also interested in @OVTune 's 04B04 Air Load Control maps, how 04B04 compares to 04B14 Stock / OVT and how the Lambda 0.82 and 0.99 values are the same. I may Zendesk my post (#3 in this thread) to OVT once I confirm the high idle question. I meant to dig into vF this weekend, but got busy with other stuff.


Oh, yeah! The thought of actual Decel maps is interesting. Although, I am half wondering if there is some mathematical weighting to inputs. Like TPS is weighted at 75%, but it is only a torque request that is then weighted against other sensors like AFR, MAF, Air Load Control correlation, etc. That remaining 25%, or even a floating, weighted split, can have an immense effect on driveability.

If it weren't for other ECUs and their interaction like the 4wd, skid control, etc., the dream of a full re-write lingers out there.

 

I'm in Northeast CT. Get in touch if you want help getting set up, or if you don't want to bother buying the whole package.

 

as of right now, just my 20 mile drive home. Im not feeling much difference beween them. i feel a bit more thud when getting on throttle and off throttle but i cant say whether that was there before or not.

The below is regardless of what smoothing was used:

I like everything down low in the rpm range, especially for highway cruising because it doesnt do that jerky crap on light throttle. But there is a "step" around 2500 where everything ramps up (i kinda designed my throttle for that by using partly stock and partly matts)

In first gear it is very noticeable, downright insane how quick it will move for only giving about 11 to 14% pedal.

This should all be customizeable through the primary throttle table, without touching the other stuff.

I think at this point im going to focus on balancing throttle, maybe moving my "go fast" range slightly higher up than i currently have it.

I may even put the factory numbers back into the 1st gear table, then modify the throttle primary from 0 to 87.5 with the only deviation being the extra bump at 700 rpm, and add Matts values a bit higher up in the map, smoothing the transition

I am primarily focused on smooth, eliminating the steppy nature this truck has always had during acceleration.

It is lightyears ahead of where it was when i got it a year ago, in fact im super happy with it. But who wants to settle for "good enough".

 

Thanks! I was getting the thud with my V1 Air Load Control maps. V2 (the ones in the spreadsheet) have not done that.


Yes! The resting foot acceleration is very real and very nice.


I just got confirmation that the Air Load Control maps in 04B04 are the same as 04B14. So, the values out of Mat's 04B04 Example tune, with matching values between the Lambdas, are good for us also! I will post those up later.



Definitely no good enough when we can play like this.

 

cool, i didnt see those numbers, only a partial from a screen shot. i didnt want to pay 79 to see them lol

 

Exactly!

The screenshots were only the edits though. I needed to verify that the unedited values matched ours and they do.
