Just wondering what happened to the walk thru link? Would like to learn more about the A6 gear.

That guide is less than impressive. It doesn't explain how anything works and just instructs the user to make a bunch of changes without understanding of what or why.

I wish someone would have told me that 6 weeks ago.

Had to knock the dust of the book to verify this one. There are 37 pages in my Advanced Tuning Guide referencing Hp Tuners specific transmission tuning...of which 30 pages are for the A6. I am clearly reading an explanation of what the changes I make to vehicles will do.

What reference are you using?

[DSteck]

The same 30 page guide. It just says "change this". No explanation of why or how things work.

Having Taken and Taught many a training class on a variety of technical subjects, some people will get more out of the class than others. While the training "Book" itself may not explain the "reasons" for the various activities, these may have been covered during the class instruction - requiring the attendees to take good notes. Not wanting to take sides, maybe one of the HP Tuners can speak up on this and "convince " people why they should take the class(s).

One other thought is, while the help files are useful as far as "definitions" for particular entries and understanding, the help seems to be lacking in the general connections for a number of parameters. I have only found ONE example input by a user into the help file. Maybe that's why the classes are offered, but I've always been under the assumption if you bang your head against the wall enough going through the help on a software program (which is my JOB in real life) before you take a class on the subject, you are much more likely to retain the knowledge AND get a lot more out of a class specific to your interest. Anyone got an extensive list of Acronymn Definitions?

Just my thought on the subject.

[SICK WS 6]

I didn't take the class. Nor do I expect to. I've been away from tuning for a few years, so the A6 was a new challenge for me. I was hoping I would get a bit more of an explanation than I did from the guide.
There's a big difference between change this to this, and having an explanation or definition for what a parameter controls or does so that you can decide whether and how to best change that value.

Don't get me wrong, I'm not upset about my purchase as the guide pointed me in the right direction and it was easy to fill in the gaps just by searching old threads on this forum. Plus I would have contacted the authors and asked for some simple guidance if I'd had questions. I'm sure that they would have helped.

[Loren]

I have every intention of taking the class, but don't have the guide. How do you get the guide?
As a programmer and software support individual for over 20 years, my issue is figuring out the program enough through the help files to actually find value without "blowing something up". At this point, the help files seem to be lacking in some areas.
As an example, why does the Auto Shift Properties have a Shift Pattern Type of "Pattern A" with a list of values preselected to "Pattn 1" and "Pattern B" set to "Normal" and which one is used in a daily drive down the street? The help files are seriously lacking in this area. (Don't exist except for the small explanation at the bottom of that particular window). Maybe someone at HPTuners can explain. Can't seem to find anything referencing "Pattn 1" or "Normal", what it does, what it's used for, what a change would do, what the other list of options are for, where they are set ..... other than "it is recommended not to change these values." Would be nice to know where they are even used and which one is used where! And "NO", hitting F1 in the help files and searching the help files does not return anything for "Pattern A", "Pattn 1", "Pattern B" or any other combination I've come up with.
Just my little disconcerted issue - trial and eror seems a bit "risky" from my perspective.

Well I can't post any direct word for word info. or pages of book mentioned in above link due to copyright infringement...I wish they offered some SAMPLE pages to prospective buyers for reference.

BUT

I can tell you that it clearly explains in my opinion what/why you are making the changes...

i.e. Which make/models have

Pattern X - Drive
Pattern Y - Sport Mode
Pattern Z - Manual Mode

Also explains which of these make/models use the actual data put in these tuning tables. Some make/models simply don't use these tables at all yet data is in the factory tunes...

For $99 I'll spend the money to see a step by step with pictures of actual Hp Tuners screen shots with explanations.

Considering the 6L50/6L80/6L90 are $2k+ from a junk yard...

You would be INSANE to try to tune a customers car just playing with the values.

Great FREE A6 writeup...(not as extensive as www.thetuningschool.com A6 book mind you) but FREE!

The $99 guide is not worth $99. There's no explanation of how to arrive at the value to punch in. That's what matters. There's no method... just "do this" and hit save.

[mowton]

I disagree about it not being worth $99. I purchased the guide after having read alot of info (including the A6 walkthrough, numerous technical notes/threads etc) and it certainly helped fill in some blanks for me and further support all the technical jargon I had read. It also provided a good foundation to allow me to experiment with the parameters and fine tune the tuning process in my own way. Best of all it actually worked first time out of the "box".

So to me the $99 was well spent...I mean after all, you pay $100+ for 1 hour of labor. Education......priceless.

As we all know, there is not a Holy Grail of tuning and any info I can get that works just furthers my ability.

JMHO as well

I don't see how anything in that would help with the A6 in a Camaro. Sorry, but no.

I believe I understand now what your mean. You saying there is no clear explanation as to "how" the www.thetuningschool.com arrived at the values they are recommending you to put in the tables.

Correct?

I'm certain they would simply answer..."Thru extensive R&D testing we have determined the following to be *true...(*test at your own risk!)"

Anyhow...

In all sincerity being sensitive to your personal opinion and of coarse your own vast knowledge of the A6.

What do you recommend beyond the $99 guide for those that seek more A6 insight?

[mowton]

My take away on their selected tuning process was to reduce the stacked layers of shift timing/torque management to a much simplier approach. This then gave you a single place to go to adjust timing and pressure per specific area's as needed. I thought they addressed that pretty well in their writeup. Additionally, it did provide several log setups to allow you to "tweak" certain parameters as needed. In all aspects they appeared to maintain the intended GM strategy and "adjusted" values to further the speed and firmness of the shift. Interestingly, some of their approach actually was incorporated by GM in their 2010 1/2 and on strategies.

To this, I believe $99 to pay for a "tool" which can add to your tuning skills is certainly reasonable especially based on it actually works. This is also based on the reality that tuners need to understand some of the basics of the A6. I don't believe their is one book/video/thread which captures all the essentials of a specific tuning strategy.

Oh and by the way, I am in no way affiliated with the Tuning School so this is just an opinion of a normal "off the street" consumer intended solely to express my personal view.

More insight? Read about other people and their experience. A lot of it just makes sense to me, so I'm not sure what to tell you.

Hello evevyone, this is my first post for a question for tune my truck for engine compression braking. I have a 2011 Sierra with a LC9 5.3l, auto with3.42 ratio. What parameters need to be adjusted to acomplish this.
Thanks, God Bless

carneb,

you are correct, after all the idea of this whole complicated system is that *it* calculates the optimum input torque to achieve the shift in the optimum way. These tables look like a fudge factor to account for any issues that arise, but no doubt they are used by calibrators who cannot work out the complicated stuff.

You will never convince racing people that it is better to let the PCM cut torque to get a faster shift that isn't as hard on parts

The shift "feel" is primarily controlled via the shift time and as i explained in an earlier post you can either mod the shift time directly or use the intertia profiles to select a higher profile at part throttle.

I think we definately have enough params uncovered now for people to make the A6 shift well. The only remaining thing i have is to find out what makes the TUTD react slowly and if it can be changed.

Bringing this from the dead , Chris, did you ever find out what makes TUTD slow, and if can be changed ?
