vF Tuning for Manual Transmission 3rd Gens

That is exactly what I have been doing. I have only edited one tune file and just keep versioning it and is also pretty much my concept for these threads. Just create patches that can be Lego'ed in and out.

So, make a copy of your current favorite tune, grab my spreadsheet, and paste in the maps.

If you don't like the change, it is either an easy flash back to the last good tune file or editing the change(s).

This is the reason that I won't post full tunes. The user can 100% know what has been touched. No guessing or worries.

 

thanks, thought so but making sure i'm not missing a better way.

you updated Map Data.xlsx on the ALC Edit thread in the OP? if so and you are updating it, would you mind having the latest modify date in the filename?

 

yeah but then i cant blame you for my bad edit lol

 

Great idea! I will do that.

I have not updated the 1st Post yet because I was feeling out the change, but I do think that I can.

 

Or, a rod going sub-orbital.

 

@tonered have you figured out the auto-blipper yet?

 

Possibly? That is where the Mello Yello comes from.

Just shocking thinking about where we started (04B10, 04B11, or 04B12). Every change (TSB, 1.05, 2.0, and now vF) has been an improvement that seems like it could be lived with compared to the factory trash. To be getting shifting improvements at this stage boggles the mind.

 

@tonered
just took a drive, and i can tell it's not fully settled, it's always seemed to settle after a second start, but i idled a while and drive about 15 miles.

04B04 ALC edits.
subtle change at this point. i am possibly identifying two things and i wanted to see if you have similar.
1) again generally more smooth on accel, less 'stage-y' up to 4k, and possibly a bit more filled out. which would seemingly correspond to smoother interpolation.
2) a numb-er throttle tip in and possibly a tiny torque hole that i didn't have before getting on throttle from ~1k. not totally sure about this one.

and i know my exhaust seems to be a differentiating factor especially with throttle response at low rpm and what has been described as the torque hole before.

spitballing.

 

Excellent!

On the restart. I have noticed a significant part of the tune settling happening after a shut down. So if I can, I am now doing the same on my first drives after a flash.

For your questions:

1. Yes. That is how I am feeling about it. At part throttle, it is all pull with no stages like you noted. Prior to, I would have attributed it to the HW (ACIS or VVTi) doing something. It could be @OVTune 's values, the lack of creases in the values, or the fact that the ECU isn't bouncing between Lambdas? Again here, I think (!) that the Lambdas are Stoic / Closed Loop and Open Loop. I cannot see how those fueling states would relate Engine Speed to MAF for faux MAP data though?
2. That is a good question. I am happy to not have the prior tip in issue that I had with my V1 edits. With the OVT maps being the same between each Lambda, I cannot visually discern all the differences. So now with a good feel for it, I will do a check in the spreadsheet to see what are the value differences between the new V3 and my V2 maps. That may reveal the answer here and maybe guide you to solution?

Good stuff!

 

great, thanks. i have a feeling that after the second start this kinda slightly numb thing will be gone totally and I'll just relearn my throttle touch like most other new flashes, and it will be a clean improvement across the board. in the meantime I'm helping turn this into a bs thread.

 

It did feel different with each run. We'll see what muscle memory says this afternoon.


BS is always good!

 

I updated the spreadsheet with a difference check and charts on the same axis scale in each of the first four worksheets.

The only one showing a significant difference near tip in is the Control Airflow 0.82?

Things diverge quite a bit on the Control Airflow maps away from tip in.

Finally i found a happy medium in my throttle sensitivity adventures.

I finally got it where I can apply a light throttle and get rid of that on/off switch feeling low in the pedal while providing smooth power where needed.

It is the exact same settings i had in my previous file, with minor....very minor changes to the primary throttle table. I found changes of even .5 or 1 to make huge differences.

It was hard to find something that didn't neuter the throttle in all gears, and also hard to get 2 - 6 feeling good without having 1st gear be a rocket ship.

These values are good for cruising in traffic and parking lots, where you will put light throttle on and off, it still has the balls when you need it.

Do note, i will continue to play with it and update any changes i make that i find better.

Anyone who may have used my file or any of my values, that found 1st gear to be kinda crazy, try the new values. The only changes made were to the primary throttle values.

@tonered since you own this thread, it may be a good idea to put links to posts in the first thread with various tips/tricks/maps/values that people can quick reference (almost like a MT FAQ section)

It would be easy to start now, before it becomes a 300 page mega thread.

My next stop will be trying the air load tables that you pulled from Matts example file.

And of course, with any driving over the next week or so, finding and fixing any issues that may arise from different driving conditions and such.

 

I am stoked that you found a solution! This will be my next edit once I completely feel out the Air Load Control change. I was barely able to make a half tank when I had hoped for a full tank. Haha!


That is a very good idea. I will get on that over the weekend.


The updated ALC spreadsheet with the shown differences might help you?

 

My apologies if this has been discussed already.
If I make the switch to VF ( and it looks like I am for what appears to be good results with the throttle smoothing edits I have read so far), I have one question:
since I will lose the dongle and access to the flash manager (I assume) If I do not like a new edit, how can I go back to the current 2.0 I am on?

 

There's no loss of access to anything other then PCM files. P5F, VFT, and BIN are still in play as is dongleless FM.

 

Thank you for all your help. I emailed Matt about getting my dongle traded in. I think after reading over what ya'll are doing it seems worth it.
I am very excited about this throttle smoothing I keep hearing about for 1st gear.

 

looking forward to trying this. to be clear, changes were made to the Primary Throttle Torque Target table exclusively?

Much appreciated

I'm sure I will have many questions. I will try and find them from the MT page as much as I can.
