I've been reading up on the T vs TS and the T does not have the capability to adjust to the driver's driving patterns.  This was implemented in 2000 in the S.

our tiptronic definitely has more than 1 shifting program.  i have something about it here is the sales literature somewhere.  there is a very brief mention about the different shifting "curves" in the owner's manual too.  it's a pretty rudimentary system though.  it's not hard to tell the difference though when you are driving.  every time i go pick up the white car from dad, i have to go stomp on it for a bit to get it back into the more aggressive program.

on a side note, and on the subject of the tip, in response to your query in another thread, the owner's manual says the maximum downshift point from 2nd to 1st is 2700rpm.  i'd swear i have downshifted higher than that though.  not sure i want to press my luck now, as i'd really like to keep it in one piece, and the flex dampener is original, which we already know to be dangerous enough on its own.

The "program" modes would appear to be associated with the D 3 2 1 and Manual.  If my math is correct that's five.  :glare:  ( I was always really lousy with math)  There may be more to the "programming" than that.  I was looking up a performance chip enhancement company in Australia that wanted $900 plus to replace two chips.  Reading more on the subject it appears that the DME and the Tip are symbiotic along with the ABS.  So its definitely more complex than one might suppose.

  

I missed the part about downshifting and 1st gear.  I must really peruse that manual again.

It definitely shifts differently when you are on it versus when you are cruising. It likely takes load input from the ecu and adjusts the valve body pressures accordingly. I also know that it takes a couple of minutes for the changes to take place.


I haven't been able to nail down exactly what differences there are. I know that the "start up" program limits revs and such. Then there is the "cruise" program. Then there is the "hot foot" program. I haven't driven the car enough to figure out the others

I think we're on the same page here. Its a little misleading in the manual as it states:

 

"five different shift curve families are available between economy and sport, whereby the shift points are changed to lower or higher speeds depending on driving habits" - maybe more succinctly it should read "driving style".  

 

When I get on it, it gets it on... and when I'm cruising in D,  it drops the rpms down at every opportunity.

 

For "off the line" Manual seems to be the best mode as it will automatically pop through the gears close to red line, only that is not necessarily the best shift point.  First gear is so low, it seems best to shift at around 3000.  Putting it in D and driving aggressively and noting the shift point from 1 to 2 (which I have sort of been attempting to do) probably indicates its best shift point and the same is true of the other gears.

 

But here's my beef on downshifting... 

 

"The next higher or lower gear can be selected at any time in the manual gate depending on the road speed."   Not true... depending on RPMs.

 

As you noted it states that the shift point from 2 to 1 is 2700 rpm.  You'll also notice that that is mentioned in "Position 1" section which is regarding the shifter being in Position 1.

But it does appear to hold true for "Manual" as well. Which shows how closely related the programming is.  I don't know how accurate these tachs are but it seems to me I've been

able to get it to shift down below 2500, which is close to the rpm mentioned.  The rest of the gears have more reasonable downshift points ( as per the Position Section) and I'll check to see

how close the relationship is there as well.

 

You got me pointed in the right direction.... B)

no worries.  the tip was pretty amazing for its day.  it's pretty lame by comparison to what we have today though.  still, it's miles beyond the previous box the 944 had, and we know some guys who actually race tips.  when you learn how they work, they can be a lot of fun, and a whole lot easier to drive on a day to day basis.  i considered pumping up the white car, and keeping it, but it would still fall short of the targa, so i have decided to let it go.  it will make a great car for somebody though, as it's really solid, and the tip makes it very easy to drive, with not nearly as much given up in performance as some might think.  again, it's all in optimizing the shift patterns.

Yeah,  I was sorry to hear that you were selling them both... there value is rapidly appreciating, and for those collectors who are into "innovations" in sports cars, the 968 is a really interesting piece of work. The way the computers (motoronic and tiptronic) are linked with the abs etc. is a real conversation piece.

to me, it's a lot like hanging onto an apple SE.  yes, it can get the job done, but it's just old and clanky by comparison to a new computer, and lacks a lot of features we have all come to expect.  i've enjoyed the time i've had with the 968, but after 11 years, it's just time to move on.  i'm not having fun with it anymore, and it can't do what i want.  i've never really been a collector of anything.  i'm also not at all sentimental.  i don't keep many souvenirs, photos, or any sort of thing like that really.  i'm very pragmatic when it comes to stuff like this.  i keep things, as long as they serve their purpose.  when they stop doing that, off they go.

Sorry, definitely off topic here but I had to point out this is the first time I saw flash properly capitalize the first words in each sentence. Ever. He must have gotten caught in some strange matrix thing.

Ayn is now editing his Forum writing! Why she waited this long is a mystery. Perhaps she wanted him to leave on a clean note.

I can appreciate most of what you're saying, but being somewhat pragmatic myself, I think what other car can I have, that is what it is, that I can park downtown with or where ever and for the most part not freak out because its such a gem... you get the drift, which is partly why my beast is the way it is.  I've had tires slashed and the driver side door scratched with what looked a lot like a dollar sign etc. but those are "fixed" and on I go... which is why I commented on the "road warrior" aspect.  I suppose its got a lot to do with where you go, have to go and what you're going to get there in.  San Diego County is not Marin...  B)
