So, lets say that your car was going in for this months visit... but you have the system "flashed" a month ago for last months visit.... Would the reflash this visit be any better than last months? Has something changed in the electronic bag of tricks (PIWIS) that makes it worthwhile doing it again?

Hey Colm, thanks for the review, but I just want to see pics of the CGT!!! Any plans to take it out to LS?

PCNA likes to tell those of us in high elevations that it's due to poor fuel quality.

"All 8 coils are bad...must be bad gas"
"The rear trunk switch isn't working again?...what kind of fuel did you put in the tank?

Colm,
Thanks for the review of the '08. At least it gives some of us hope for a retrofix, however dim that hope may be.

As for your never engaging PSM: no powerslides? Ever? You're a better man than I. I think the last vehicle I owned that I didn't push past the limits at least once was my tricycle, but everyone gets to choose his own risk factors. If you ever push the Cayenne hard, you'll find that the PSM is more intrusive than on the 997, allowing less rear drift before activating, which is probably appropriate. In daily driving, the "stability" part of PSM is not a problem for me, and actually would be quite desirable.

But the real reason that I deactivate it in daily driving is that, perhaps due to my lack of finesse with the Tip, I find that the tranny will downshift quicker in Auto with PSM off than it will in Manual with PSM on, unless I have at least a full second to anticipate the shift manually. This is most notable when dropping more than 1 gear, which takes the manual Tip quite some time to think about. Maybe it's just my vehicle, or just me.

I drove a 08 TT yesterday and agree, the hesitiation is gone, from standing starts, rolling starts and tranny kickdown. They fixed the problem. I drove a 06TTS a few weeks ago and I preferred my 04 CS to it, due to the hesitation issue. I guess they are finally listening to us.

Fixed the problem ?
That's funny, I don't recall PCNA/PAG EVER admitting to a problem.

depends on what car youre coming from before buying a Cayenne..
My friend who drive an lexus GX wanted to get rid of his car, and get a Cayenne V6, I told him dont.. and wait for the redesign..he drove a
V6 and loved it, and he thinks the CayenneS is just phenomenal, I think he would be a good example of a "few thousand mile owner experience" that youre talking about


That's what he's doing driving around in the CGT..

Saw it yesterday in Santana Row, beautiful car...

Congrats Colm and thanks fro the review...

This must be Colm....
Beautiful!!

According to the promotional material on the 2008 Cayenne, the new CS and CTT come standard with a "new transmission" called Tiptronic S, while the base Cayenne gets the old Tip (or 6 sp manual).

The description states that there are:

"multiple gearshift patterns, from a basic 'Economy' program for normal on-rad driving to a "Sport" setting that maximizes the engine's performance potential. Each gearshift point is automatically selected based on current driving style and road conditions. Typically, Tiptronic S automatically changes gear precisely when you would have yourself. Within a short space of time, you'll be able to influence gearshifts using the throttle alone. The benefits of Tiptronic S are particularly apparent in Sport mode. The immediacy of response, with practically no interruption in acceleration, is comparable with that of a manual gearbox."

The description, which goes on, seems to specifically address the "hesitation" issue noted by many--especially when one considers the last sentance in the above excerpt.

Please allow me to go out on a limb here.....

It sounds strikingly similar to the Sport mode (button) used in the Carrera/Boxster lineup...and I'm going to go even further and suggest it will also be strikingly similar to the Panamera transmission.

I'm also going to guess that the transmission is still produced by Aisin and mechanically bears a striking resemblence to the current (re: "discarded") transmission previously mentioned.

In other words, same H/W, just a button to activate some new S/W in the TCU/ECU.

Then again, it's just me talking to myself again......I'm sure no one heard this.

STATMAN

Okay... I think I heard a faint rumbling from the tomb of Larry. Yes, I certainly noticed that the 2008 CTT and CS are equipped with the Sport mode button just like in my 997S (along with the PSM on/off button as well). Beyond the addition of the Sport mode button, I suppose the rest of the promotional writeup I quoted previously could have just as easlly applied to the "old Cayenne Tip."

So, this may be a fancy was of saying we added the Sport mode button--like in the 997 and Boxster lines--but did little if anything else and, oh by the way, we decided to give the transmission a cute new name, "Tiptronic S," to help is sound truly revolutionary (or evolutionary--to use the proper Porsche vernacular). Does that sound about right?

Drop out the ‘S’ and ‘Sport’ setting references and that _is_ the copy they used to describe the Tiptronic transmission in the Cayenne originally.

In some promotional material Porsche went on to note that the Cayenne’s Tiptronic transmission took just about _everything_ into account to facilate:
- Active shifting into most sporting map
- Prevent deceleration upshifts before curves
- Downshifting during braking
- Holding gear in curves
- Staged upshifts take place in stages

Obviously the ‘holding gear in curves’ feature does not translate into simple turns on city streets for many of us.

That written, the latest DME update has been making a difference for me. It seems to have going much further than earlier DME updates to address many of concerns. I’m getting engine response (felt and heard) even when I ease the accelerator pedal on lightly at low speeds and in stop and go traffic. I don't recall this as being the case with past DME updates.

I'm also beginning to wonder if this DME update lets the boost build up sooner than prior ones.

The jury is still out for me as to this DME update helping out on gear selection coming out of in-city turns.

Like Enigma I’m just wondering when/if the gains are going to be adapted out.

ltc,

A true cynic (which, of course, I am not) reading your post would think that P might have done the following with the new Cayenne:
1. Eliminate the granny mode from the TCU, such that it responds like the old TCU with PSM off - then call it a "new" transmission, the "Tiptronic S."
2. Put in a Sport button that doesn't do anything too dramatic, as with the Sport Chrono on the 997TT, but rather just adapts the ECU throttle settings to the same as those with the PSM off.

Such adaptations would have the advantage of "improving performance," while leaving the stability features of PSM fully functional - a significant advantage for owners, but, more importantly, a whole new marketing campaign for PAG. If this was, indeed, the approach, it would seem to indicate that they must have determined that it is the throttle settings, rather than the transmission settings, that affect the gas mileage numbers more substantially, since that is where they restricted the "new" settings to a selectable option.

Of course, if such cynical thinking were accurate, there would still be the question of the "adaptive" granny mode. On the other hand, a true optimist would think that real (albeit just SW) changes have been made and that Bancu's DME update won't adapt toward wheelchair mode over time.

Keeping my fingers crossed, - cynically.

IF?
Trust me, there's no IF.
