vF Tuning for Manual Transmission 3rd Gens

You use CTRL (Control) + C to Copy and CTRL + V to Paste, right?

CTRL + I does a global edit over the selected cells and just makes them linear.

 

Only the Airload Control Maps were altered:



1. I stole your smoothed airload maps from 'hatch's file (I believe they were V3?);
2. Highlight area from 45.833 to end of map on load axis, and from 300 to 1000 on RPM axis - increase area by 10%;
3. Highlight same area on load axis but from 1000-1600 on rpm axis - CTRL I this area; and
4. Highlight same area on load axis but from 300-2000 on rpm axis - CTRL I this area.

The reason I smoothed in two distinct steps was so that it could be replicated.

I then did the same thing for the .999 Airload Control Map (or you could just copy paste the whole thing from .821 to .999).
Expected airload was not altered.

 

Alright, so I went into the hyper linear throttle map I've got as a back up to try out (copied what @tonered had posted up) and removed hatch's PTTG1 from that, removed it from my own unintentional SFOB REG Performance map that I'm trying out as well. Turns out I had already done the CTRL-I smoothing for the accel-airload table. I suspect I didn't name the file accordingly because it gets on my nerves when the file names are exceedingly long lol

Revisited the PTTT table yet again and made the first column -7.5 per friendly suggestion (which should also increase some engine braking too, no @MOC221_ ? so that's a win anyway) and then made the change shown below.

Re-smoothed the first four columns from 1400rpm up, and I've got the fifth column highlighted just because there was an odd torque dip in there that I'd happened to see at Accelerator 17, 1600 rpm iirc. Going down the column it read 20, 10, 17, 17, it was just random and weird, took that out.

Will test. If this doesn't work out, or if it's at least not super close to what I'm looking for overall, I'll probably abandon this line of tinkering and just throw up the map for others to grab and use if they want. These edits haven't been bad at all, they've resulted in very fun, aggressive and smooth driving. Just not how I want to drive my truck. Lol

 

Good luck!

Finding the Goldie Locks settings can be a challenge. Going by feel seems to be the best route, short of detailed information that we don't have at the moment.

Getting impressions and map data is the way forward.

 

Thank you!

If the ALC maps are the same between the Lambdas, then it was my V3 maps.

Nice work. I hope the smooth tune fun continues.

 

Yes going more negative in that left most column (full lift on the accelerator) on the PTTT map should increase engine braking in my experience. I've not tried putting the exact same values down that whole column yet though.. I'm using a "stock" config for that map right now. I want to see how my current combo works out and THEN fuck with the PTTT.

 

Thanks, I did this mod to your maps see if I could get the low end grunt back right off idle. It seems to have worked in my case. I had modded my own airload maps in this manner previous to trying 'hatch's tune file.

 

Ugh. Alright, so I guess I need to either reapply hatch's PTTG1 map or return the 1st column of the PTTT to -5

Throttle isn't as sensitive. Nearly identical to Mat's SFOB Reg that I'm using as my base. I've now returned to needing to double tap the pedal when downshifting into 2nd to get the revs to come up anywhere above 2800-3k. That dead pedal feeling you get the first time you press. Smh.

Everything else is pretty great so far.

 

Just curious. Are you tapping at just the start of the pedal when blipping? I am finding that just like the in-gear throttle, I need to get into it a bit deeper for rev matching. On larger downshifts, it is sometimes a fast stab to the floor, but there is no deadness, just what I would still call linear response?



With the powa of vF, I hear that @MOC221_ almost has the AutoBlipper sorted out!

 

I guess I'm just tapping because for the other gears, a tap gets you right to where you need to be. This isn't the case for 2nd since I typically downshift into it at 35-50mph, and so I need on average to hit 3k to almost 5k rpm.

Going deeper into the pedal for a longer and more deliberate press will absolutely be a learning curve then, and not at all what I'm used to for downshifting. More ugh.

 

On my more aggressive previous revision it was excellent. Tap it like I'm used to and bam, I was where I needed to be. Lol

 

Yes. It is a more deliberate action, but I have been butter smooth so far. To be honest, it is reminding me more of past cars now? Forgotten sensations are bubbling up?

 

To me it seems slow and irritating. So I've gotta decide what I want to do

 

Interesting. It doesn't seem slow on mine.

I'll see if I can get some repeatable numbers out of the logs.

 

This has been my nemesis for a very long time! Sometimes only a tap is needed, others you have to double tap or stomp.
There always seems to be a trade off in weirdness when you get a quick, snappy blip response though.. driveability suffers in other ways.

 

Just curious, but what are you seeing with these edits?

With my last edited tune, it was very consistent for all but a couple shifts. The current one seems even better.

I honestly think that all this simplification (taking decisions away from the ECU) is actually doing more than the sum of the parts?

 

not here as far as i can see. light brush of the throttle consistently gets the rev bump i need to rev match reliably. maybe you would identify all kinds of driveability problems with my truck but i see essentially none.

 

Good point!

 

Did you change the gear 1 table at all?

If you did then that will affect this as well.

In my maps i last posted i had a hybrid of stock in the low end and ov tunes in the high end.

If you return that back tho ovtunes it will increase throttle sensitivity. I found it to be too sensitive

 

Those are/were @tonered maps
