I drove the new CTT with the PDCC and I was impressed.

The responsiveness is amazing (and I mean transmission too), the kickdown is instantaenous and pick up is delightful. The car feels a lot lighter than my 05 CTT, delivers a very significant improvement and an equally pleasant surprise.
My expectations were that it wouldn't be very different.

The PDCC works very well in corners and will induce more than its share of speeding tickets. I think those of you who are getting this car are going to be jumping with joy at the improvements.

And I'll be interested to see if you all agree with my take on it

Thanks Colm.

If I do not intend to track or take the truck off road, do you think the PDCC is beneficial to daily city driving? or will it be a waste of money? Thanks.

But will it stay responsive is the big question. How much faster did it feel? (I have a 2004 CTT). Did you try the "sport mode"? I'd love to hear how it differs from turning PSM off. Thanks.

I'd definitely go for the PDCC it was great on the twisties, hence my ticket reference.

My CTT has never been as responsive, even when driven spiritedly to bring it out of lazy mode. The kickdown always required more pedal travel too, even in non sport mode. In the new one the response was rapid with small throttle input (hence my surprise).

I tried it in Sport mode too, and it is very responsive, too responsive for street driving IMO in an SUV, and I drive my 997 in sport mode all the time.

Turning PSM off, I don't go there.

How long will it stay responsive, I can't say but my 05 never performed anything like it. I even drove an 06 Turbo S back to back with it and much preferred the 08 Turbo.

If what I observed is verified across a number of cars then I would venture to say that the "hesitation" is gone.

OK, so who is going to ask if the 08 CTT ECU is the same as the 06 CTT ECU?

Then, who is going to ask if you can use PIWIS to flash the ECU in an 06 CTT wtih 08 CTT F/W?

PogueMoHone

I didn't ask but I was wondering if in the near future there now would be a new TSB for 06 and earlier.

Me. Me. Me. Let me be first.

Actually, I guess we don't need to. You beat us to it.

While we're at it, though, who's going to ask why Colm never turns off the electronic nanny in his CTT? If i couldn't do that in my '05, given what it is like with PSM on, I would have never bought the thing in the first place.

I was going to ask, but I guess you beat me to it, so I'll ask regarding the "hesitation is gone". Wouldn't hesitation appear down the road, few thousand miles later? From what I remember, my CS performed beautifully and without hesitation when I test drove it.

Bancu's quote would be appropriate here:

I can flat out tell you the CT I drove off the lot new and half way across country was not the one I had after driving it around town for a while.

Vino

Colm, thanks for review!

PogueMoHone

You guys!

Here goes!

1. The 06 Turbo S and 08 Turbo were driven directly off the lot, and both had about the same miles; so they were directly comparable. I'm on my second CTT (first one wrecked) and I understand the "hestitation" problem, it was identifiable in the 06 Turbo S but the 08 is a different animal. The comparison with regard to time should be the same, because initially there is a significant difference, you'd expect both to change in the same way (if you believe they change).

I am putting down a marker here, over the next few days more people will drive this car and we'll see if they agree.

The PSM staying on is a personal issue. I have never triggered the PSM in my 997S on the track (or at PDE) and that is either because a) I don't go fast enough or b) I am smooth with inputs or c) both


I know of no reason, with street driving, to get the performance out of the CTT (manual operation, if required) to turn off the the PSM.

I wonder to what extent this improvement could be ECU-related OR related to the apparent improvements that may be associated with the direct fuel injection feature on the 2008s?

Colm: Where have you been of late?

PogueMoHone

I have been everywhere man (old song). Just spent 3 weeks down under, combined with the usual travel I have only been home for 2 week-ends since the start of the year. But, I'll be home this week-end.

OK, let's follow that idea for a bit....

If, in fact, the Cayenne V8 was fundamentally imparted with hesitation due to the first generation fuel injection/induction system (MY03-MY06), then PSM On/Off would have no effect on the reported 'eGas hesitation', correct?

It's the S/W, you know it, they know it, they never had any intentions of ever recalling 50K vehicles to the workshop for reflash for such an issue.

Example: the current Honda Civic Si bucks like a bronco when the engine is cold. It's a fact. Honda knows about it, but isn't going to do anything about it. Why? Because if they do remap the ECU, then they have to present it back to the gov't for CAFE/CARB recertification. So, they have told customers "it's normal". Of course it's not a problem in their 2 biggest markets (CA and FL....where it's warm......that helps).
BTW, a friend owns one who has a Honda dealership. He went thru hell with Honda over this one. In the end, he simply did a ECU reflash from Hondata (aftermarket performance company who has a good working relationship with Honda).
Voila! The car runs fantastic in freezing weather cold starts. Who would have thought?

Vino

Probably not.

I think this all comes down to the electronics incorporated with the transmission.
You can stick any year of CTT in first gear, gas it and the pick up is almost immediate, even in 2nd with PSM on.

The downshift is the major issue, either after coasting for a while or during turns and needing speed quick while in motion.

I think a good start is to see if the new Cayenne is still using the same transmission as before and if control modules have changed.

Anyone have a current parts catalog on their system yet so we can see what has changed?

If nothing pops up in relation I will have some info for you guys early next week.
