I remember one of those GM slides saying there were mechanical and software improvements to the 08 A6. Could you venture a guess as to the long term effects of running the newer 08 software/module on an 07/06 A6?

Also, do you work on a exchange basis? Some of us use our cars as DD and cannot afford any downtime during the week.

Just had my car done last night it. it shifts like a F1 car fast.

Thanks chuck .. great job.

Next time i am going to bring my pillow.

PS. I have a 2006 A6 Z51

Wish I had an A6....

Ive been reading that Chevy is reflashing older units to 08 specs. Is this the same thing? How much?

Mike's car was the test mule.....

Ain't no mule now!

For my EXISTING customers.....FREE!

For new customers....The tunes here are always $500. and $400 for mail order AUTOMATIC tunes.

Chuck Cow does it again

Chuck, I'll be ordering my new '08 valve body for my '07 cause I like being shiftless.
I'll call you re: when we can install and retune.

But you didnt answer the first question. Is this the same thing that GM is supposed to be doing?

0Chuck CoW

ANSWER: I don't work for them and I don't know what they are doing.

Their software does not permit such changes UNLESS it's mandated from corporate and the TIS programming system is modified to make it work.

As of "very" late last night, I saw no evidence of any software being available from GM TIS for Mike's 06 A6.

While it is possible for the engineers at GM to make any software they want available to anyone....I've only seen it a few times and it only happens when there is a problem they can't fix by conventional methods.

It's unlikely, and NO, I don't think they are offering it.

I have only drove the 06 & 07 A6. Does the 08 shift and drive that much different. I have an 06 and I love the A6 but would love a little more of a positive shift feel.

The change is not massive...but nice. The real deal (from what the engineers told me) is the shift strategy and shift timing....The adaptive learn stuff. In other words...stuff you'll appreciate, but not stuff to get you to the finish line quicker....That's my job!

Cool, now if you can figure out the throttle blip on paddle downshift I'll really be a happy camper. On this 08 update do they get the throttle blip on paddle downshift before the tune?

Evilways

The tuning changes GM did to the A6 for 08 is actually detremental if you want performance. They added higher Torque Managment to the tranny to make it appear to shift quicker to the driver. It handicaps the peformance of the car moreso than that of the 06-07 A6s .There has been more 08 A6 trannies fail than all of 06s and 07s combined due to this increased nanny causing issues. What COW does is sooooooooo much better. If you have a stock A6, a real tuner is the way to go to make that car awaken.

0Chuck CoW

Yeah, but.....

Yes, they'll get it...but you're telling me it's gone now. I have yet to actually see one do it.....

but, you know me....I never drive em stock!

PM sent your way Chuck....

Craig after Chuck redoes my A6 tune I'll let you drive it, so you see how a fast LS2 runs... .
Seriously it is fun and you can drive it, btw did our pal make it out west?

Chuck,

First off, WOW!

Now that we've got that out of the way, I've got a few questions for you.

1) Does the 08 hardware (not just the software) swap into the previous version A6s?

2) If the 08 hardware (with software presumably included) swaps, any idea on cost and availability?

3) Is the 08 hardware (not just the software) faster than the previous versions? I've heard the processors were faster from several tuners.

4) If hardware swaps are available, will you offer them and if so, with or without the famous CoW software tune?

0Chuck CoW

Here's what I know.... I don't know anything about the processor being faster...If fact, I doubt it...I just think some guys guessed that it might be cause the unit is reputed to be better.

The actual difference is in the hydraulics and the software. I know for a fact that the operating system of the 08 is much different in that decoding it to create the tuning software took extra time while the 07 was nearly identical to the 06 models.

New features like REV-MATCHING were included in the 08's and several other things that you might not necessarily notice, but they are there for your benefit.

I believe (and they would have been smart if they did) GM made the controllers "bolt up" so I would imagine that the 08 controller (w/ integral hydraulic unit) should be a retro for the earlier trans. Otherwise they would have had to change the valve body as well.

I believe the controllers are finally available from GM for like $600. bucks....but I also believe they charge a core charge even though the unit is new. Don't quote me on this.... Someone Please check and let us know.....

I can put the 08 software by itself or better yet, the 08 GM software with MY A6 tune. Then you're ROCKIN!

Stay TUNED!

THen you really need to drive a stock one so you can experience the rev matching downshift when using paddle mode that you refer to in post 20. Comon guys, Chuck thinks I'm nuts. Can some of you 08
A6 guys jump in here and confirm that when downshifting in paddle mode on an 08 A6 the engine revs up to match the next lower gear..
