vF Tuning for Manual Transmission 3rd Gens

Changing the zero column to all -5 from all 0 felt like it increased engine braking, but also made for an aggressive driving experience, especially in lower gears, and a few times seemed to fall on its face during take off in 1st, although idk if this is due to me getting used to it, or because my table goes from zero to 9.5 lol (using tonered's PTTT table from awhile back, not the one he showed this morning)

 

Oh yeah! That 10% leap was crazy and was why I did the smoothing on the first four columns for the V1 PTTT map. I would say to re-smooth if changing one of the perifery values. I did that with @92ehatch 's table when using -5.

Alternately if you want to use something other than straight smoothing, the new ability to edit axis values is pretty damn cool.

 

Yeah so this is what I just tested. Took your v1 (iirc) and did the smoothing you'd recommended and tried that out yesterday and this morning, then just now tested the below map, which was just that -5 in the 0 column.

I may change the 9.5 to 5? And then smooth? Is it worth even touching the 30's in the 700 row if they realistically wouldn't even be touched? Maybe bring them down or include in the smoothing regardless? After all, initial take off brings revs up to anywhere from 14-2k I guess ...

 

I like the stronger feel that it's got. But it was pretty aggressive when it didn't need to be lol

 

Yeah. If you like that map, I would say to re-smooth the first four columns with the new -5 value. I didn't like that wall between 0.0% and 9.5% Changing the axis to 5% would make it worse / steeper, IMHO?

Even me, who does drive in very bottom of the power band, would not worry about that 30.

Yes! Even my worst edits felt really good except for Tip In. Whether non-CC or CC. It was just too tricky and annoying, but once past tip in, it felt like a champ.

 

I'm just gonna assume it's the exhaust differences especially after watching the last few posts of y'all's. those changes lessened aggressiveness and made things numb. i have definitely found my zone now.
1) 04B14 2.0 SFOB Prem (93oct) dump tube file with:
-- Accelerator - Acceleration Throttle Request to Airload - CTRL + I for full map (linearization)
-- Engine - Vehicle Maximum Speed Global - 312kph / 200mph
-- Torque Model - Torque Calculation Base During Full Throttle - 5000
-- Throttle Management - First Gear - 100% (all four maps)

don't think it can be better for me unless someone comes up with some tq or hp magic.

 

Alright, just smoothed these, think that should be good or should I have included 1300?

 

Nice!

Yeah. Interpolation isn't the right word. Basically a straight average between the endpoints. Linearization is definitely the best description.


I honestly didn't dislike the Stock / unedited OVT values until I saw them. But then, something that we did got rid of that medium throttle take-off hump.

 

That looks good. The 1,300rpm values look great to me.

I think you will get the smoothness and urgency from that.

 

I have all those changes included as well lol

The differences between our truck begin there. I'm running 2.0 SFOB Reg w/ 91 Oct, and have the TRD exhaust

 

About to test.

 

Think we can get Mat to write a patch that increases the number of cells on the Accelerator axis of the PTTT map lol??!!

 

There could certainly be more, esp if you want to get a nice curve in there.

I can't remember. Did OVT say what the actual calculations are between values and 4D maps? I can see it doing the math to the actual value or just picking the nearest. Picking the nearest would seem to take more computing / math?

There is also this little blurb:

 

noted, thank you. i assumed that was what "I" as in ctrl-I represented, although selecting the whole table appeared to show a different function.

 

Yeah. It definitely only considers the end point values. Interpolation is good. At least, I wasn't throwing extrapolation out there.

 

removing the TRD exhaust, as mentioned before, changed everything with how the motor revved and responded to throttle for me. it makes sense with this little 3.5 low torque unit. a bit of restriction goes a long way in holding it back. everything over here seems to validate it but it's all the butt dyno.

 

I updated the 1st Post with @Karminski 's ToC links and added the missing PTTT 1st Gear edit from @92ehatch .

 

That was a great edit. Included a picture in case anyone gets curious and tries it out. Pretty sure it's being used in conjunction with hatch's PTTG1 table.

It's strong. Feels strong down low but appropriate. Feels very BFO down low, strong but not super light like the first FOB. Once you hit, 3500 though, in any gear, you can get moving quick, no doubt due to the other throttle modifications and the rest of this PTTT table.

 

Nice!

 

Will continue to see how it goes. This will probably be the first time I'm interested in how it does for fuel economy too, since I'm taking my road trip in about a month. If it's at least equal or only slightly less than Mat's 2.0 SFOB Reg, then I'm set
