So, you want to be a tuner? Look no further.
 

Evening,

First the bad news; audio quality is poor, and I didn't edit it because it would take me several days to edit the dead air for something that would have bad audio anyway.

However, due to my impending Doctorate - I will likely never teach this course again. So I'm hoping that those who have already taken the full hands on course chime in open source style and we can all learn from each other moving forward as I will simply not have the time to aid everyone as I'd like too.

So without further ado - enjoy 12+ hours of tuning excitement including hands on Cobb and Mazdaedit action. Any crying about the format of the video or the audio quality are more than welcome to try and change it.

Here is how to play these files:

You will need to download TeamViewer (which is a cool software to have anyway) at http://www.teamviewer.com/en/index.aspx

And here is the link to the videos.

They start with 1 - and go to 10.


Maybe someday - I'll redo it in a professional format.

Or better yet, one of you smarty-pants take over for me and start running the show.


Here is the link to the source files:

LOL @ your wallpaper

My wallpaper has no equal in either manliness, awesomeness, patriotism or Murika-ness.

George Washington was a bad ass.

looks like I'm going to be up for a while

dling it right now, should take 10-15 minutes for me (300Mbps line baby)

See if I can convert it, haven't do video editing for a while.

Cool. Must be nice to have mad bandwidth.

Bandwidth is cheap here, i can go 1gig at anytime for just 20 bux extra, lol

Everything is in my comp, gonna check it out tonight

im excited. i need to start learning. Thanks for putting all your wisdomly knowledge online for us

wow thanx :)

Kane,

Congrats on Mod status!

Also anyway you can upload the actual PPT and or any of the data sheets used.

Thanks Kane!!!

I'll put the source files together when I get time.

Hey thanks I've wanted to catch a class for a while. Hopefully the videos will make due.

Added all the source files.

Murika.

Oooooo

Well I feel fucking stupid now...

:lol:

Why?

Raise your hand if you had a personal tuning session from Kane, but you still have been watching these videos over and over to validate what you learned

*raises hand*

lol love this

*hand raised*

I'm hoping we can get discussions going on here - let's get the masses involved and those with experience can help me out.

After the class, I have taken a few more logs. Some just driving, some WOT, some idling.

Normal driving isn't telling me much, because I don't have the patience to search through that much data and find issues. I do how ever intend to spend some time writing some macros that will search the data for me and essentially tell me which cells in my AFR tables need adjusting (or more appropriately, the VE map).

However, the immediate items I can tackle right now are looking at my idle logs. The most recent three logs have shown that my LTFT have been at -6.4, -6.4, and -8.74. I adjusted my injector bank 1 size to + 7% (multiply by 1.07) to see if that would correct the issue. After relogging my RPM band and getting a new idle log, on average, my STFT are now hovering around +3. I then reduced the injector size by 3%, and we'll see how we do tomorrow.

On a completely different note, I had a question about the power tune that we created, Kane.

What you had me do was to go through the AFR maps and adjust any cell that was below 12.1 to 12.1, then add in some safety factor to the high rpm/high load ranges.

My question is do I need to make this corresponding adjustment in the VE fuel tables? In those same ranges, adjust the VE to be 1 so that the map is truly hitting 12.1 instead of .92*12.1? Or am I misunderstanding what the VE table is doing?

Thanks.

I want to care, really. But no matter how many times I tell new tuners to stay away from the factory VE map they head straight to messing with it. There's no point trying to help people who are bent on messing it all up regardless, so why not let them do it all on their own? The really sad part is tuning something like a Cobb AP is so basically simple if you just focus on getting the desired output rather than unnecessarily becoming fixated on making the input and output match up.

Also, tuning methodology has to be geared specifically toward the tuning device being used. While there is a lot of crossover on general principles, the specific device defines how you go about getting the desired result. As an example, adjusting the VE map on a dedicated aftermarket ECU can be a preferred place to start as opposed to the Cobb AP on a factory ECU.

no. Do not touch the VE table. Well, in some cases you have to, but right now isn't one of those cases.
Think of it like this. Your fuel table is what you want to hit, "12.1". The VE table is just a piece of the equation that brings you to the desired AFR you input into your fuel table, "12.1". If for some reason you can't hit the desired AFR target, you input into the fuel cell and your MAF & Injector Scaling is on target, then you can refer to the VE table to make the changes in the corresponding cells.
An example of where you want to use the VE table is something that some of us see in the 6200-6300 rpm range. the Volumetric Efficiency is changing here due to the ports opening. I saw consistent lean spiking here so I went to the VE table to add the fuel needed to control the lean spike.
Hopefully that was helpful and I didn't pass on too much bad info...

^^^ That. Perfect explanation. Use the VE table only as the last resort (well second to last).
