vF Tuning for Manual Transmission 3rd Gens

Ginger 2.0 can’t make anything easy lol

 

Don't use that word around her... she's right outside.

 

Oh yeah. You just kinda know after the first few shifts. But still from the sounds of it, I was expecting a bit more.

 

Has anyone else noticed that the fuckery after LV reset has been lessened with these mods?
It might all be in my head but the learning seems to sort itself out faster.

 

I mean, the airload v4 felt a little different than v3. Idk if it was good or bad. Hard to tell too much of a difference. But not feeling bad whatsoever.

My throttle sensitivity improved. I could easily downshift into 2nd if I reminded myself to get a little deeper into the throttle, but I didn't have to bury it at all like my v2, and i didn't have to get on it much more than the regular SFOB. I like. The -6's seem to lean a little bit more towards the -7.5 side of the spectrum when comparing -5 to -7.5, which is great for engine braking, not as good for throttle sensitivity but I found it to be a happy medium. -5.5 or something like that would probably be pointless.

Learning to modulate my pedal with the linear Acceleration to Airload Request table isn't too steep of a learning curve and results in strong acceleration whenever you need it, smooth. Not in stages. And when you're not accelerating off, you can feel the "potential" to do so, the knowledge that you could if you wanted to.

 

Yeah within a quarter mile or so, it's already begun to figure out its life

 

That's better.

 

Do you have an altered PTTTG1 map in V6?

 

Yeah, hatch's

 

I've got it in v4-6

 

Cool, thanks

 

im using a surface pro. i have to connect, start it, flip my surface upside down, fold the keyboard under. reverse steps for stopping.

My last file that i sent out/posted had a really agressive lead up in that area, but was my best feeling one yet.

The last one i had (the dead throttle one i was stuck with) was honestly my best feeling one of all of them, it accelerated soooooo smooth and powerful that i loved it. You just couldnt take off on a hill or the damn thing would almost stall.

its horrible i agree. thats my main focus, all my other finds have been by accident.

The stock/ovtune hyrbid? or the linear one? (not sure i posted the linear one)

Im working on something else right now, with a crazy thought i had.


Im not sure what you guys have done so far. But i have been testing extremes on each end of the spectrum to try and see the results, going too far down, too far up, and settling in a middle area.

Im attempting to figure out the correlation between the PTTT and PTTG1. I am trying to figure a mathematical formula for relationship between each one and resulting throttle angle.

or at least one that will be "semi correct"

IE: if PTTT = 10@ given RPM and PTTG1 = 100 @same RPM then

Multiply 100x1.1 = 110 = Throttle angle X

On the flip side, if PTTT=-10 then subtract 10% =90 = Throttle angle X

my hang up is the way we track throttle angle. vlady says tech stream shows 3% is idle. OVtune shows 14%, vlady said this is motor angle?

Relative throttle shows 0% when throttle angle shows 14% Relative will increase and decrease with RPM changes and speed even with not pedal input. While the Throttle angle will sit still at 14%

the PTTTG1 map shows throttle angles all the way to 0. This only makes sense if the truck will actually go there, and i believe it does and vlady is on point with his hypothesis.

Im treating 14% as 0 and 82% as 100

so a throttle angle of 15 (29% in logger) is actually 22% throttle = 19degree throttle (if you multiply 22% x 90)

its probably all wrong lol

..../thought of the day

 

Pretty sure I'm using your OV/hybrid PTTTG1 @92ehatch

Has a scooped shape to the map in low rpm range.

Whatever one you posted quite some time ago

 

@tonered would you mind logging a short drive with your current setup, try and get some full throttle first, second, third gear. speed doesnt matter, just some short sections of full throttle and upload it here.

i would like to compare something.

 

I certainly will. I might have time tomorrow morning.

 

The Surface Pro works great, I just got to remember the pen to hit the button.



Pro Tip: Ignore vlady.

 

Take a look at the Accelerator - Request to Airload table. The graph looks similar to the Airload Control - Control Airflow 0.999 Lambda table.
I'm thinking modifying one parameter isn't enough if that parameter references other tables.

 

you mean always keep these in sync however you change them?

 

That would be my guess. I have no way to confirm what the Accelerator - Request to Airload table affects.
I'll apply the changes this weekend to see if the butt dyno can tell a difference.

 

True, but I definitely had issues with a small change in one section of the ALC maps. Going linear on the ATRA only seemed to do good things?
