Yes, the throttle blips to match revs on down shifts

What does your A6 tune change?

0Chuck CoW

Everything.

Everything from shift firmness, throttle response, shift times, adaptive learns, WOT shift points, torque managment, You name it...I changed it.

Here's what we think.....Last night I had a long A6 conversation with a guy in Austrailia....

We spoke about the 08 A6 rev matching and we collectively agree that removing the torque management for up and downshifts is why it seems to have disappeared after an aggressive tune.

I think it's a worth while trade off.

I noticed this as well. its really cool keeps the rpm's high with chucks A6 tune its even more.

To the O.P ~I know someone thinking of getting an 07' A6 so I will tell him this because he thought the 07's response was too long when he test drove one. He'll be happy to hear about this, I will give him your #

Thanks VERY much!

Now wait a minute. Are you saying Chuck did your tune and your car still blips the throttle to match the downshift when using your paddles?

0Chuck CoW

ah HA! See....

It's all in your head!

Seriously though...I absolutely believe that if we turned on the torque management throttle blip would come back....but then the car would be more of a dog.

I don't think the car is "blipping" the throttle...I believe that the PCM closes the throttle body and drops the spark timing and when you change to a lower gear, the rpms jump up as a result of the gear change no different than if you just yanked the stick back...

Our 2008 A6 Convertible does rev matching with all downshifts using the paddles. We have the LS3 and NPP option.

Works great!

Chuckie's tune on the '08 is awesome!! You get what you pay for. He touches every single aspect of the computer. Guaranteed no one else can come close to his magic. He spent a lot of time playing with stuff on my car, and it is absolutely awesome! No short cuts with turning off codes, and taking the easy way out to get performance gains. You car will still LEGALLY pass inspections.

Nope - you are wrong on this one Chuck. The computer actually blips the throttle just as you would manually with a manual trans when downshifting. Seriously, go drive a stock 08, you can't miss it. It's quite noticable. I went from the 07 A6 to the 08 A6 and it's night and day different on paddle downshift. Go drive one and figure out how to make it work with your tune.

Hey man....Call me....I wanna explain what I meant by my statement.

hmmm.... I was payin attention when I was drivin today in paddle mode. My 08 A6 does slightly over shoot the rev match when I downshift, just like if I had a stick. On a brighter note just a few more miles for the shakedown on my 08 then it's off to Chucks for the tune!

I gotta go with the other drivers of stock A6s. I don't know what is meant by 'blipping' the throttle, but it definately increases the RPM when you downshift. In fact I would say it is almost scary when you experience it for the first time. Right when you expect (or even need) some engine braking - when you downshift you actually speed up before you start to slow down.

At 4000 miles on my 08 now it is merely annoying enough that I avoid downshifting, and this certainly takes a lot of the fun I thought I would have from having the best of both worlds - an automatic that I can shift and downshift myself.

All my Corvettes have been automatics, and I have always been able to enjoy a downshift every now and again. It seems kind'a sad that those days are gone...

When you go to Chucks, make sure he drives your car FIRST and show him what we are talking about. I don't know much about PCM tuning but I really don't think teh rev matching has anything to do with torque management.

Chuck - can't you just call your contact at GM and ask about this? They've been asking you lots of questions about what you do for the A6 tune. Ask them how they are doing the rev match.

I know what you are referring to and it does seem to hold the speed a bit longer at some speeds that you downshift at but I'd rather have that back then have it practically drag the rear tires on downshift.

I think I am going to have to break down next summer and take a trip to NY

Hey man...You don't have to! The point of this post was that I've finally figured out how to do a MAIL ORDER A6 TUNE!

You can just send me the controller....

Chuck, I know you are out until Tuesday or Wednesday but I am actually yanking the TCM as we speak. When I get it out and ready tomorrow, I will post plenty of pics on a seperate thread for you and let me say this is MUCH easier than I thought. Just please tune my ECM and TCM as well as you can! I needs to go faster!
