Does anyone know whether the Tip program can be modified?

Im pretty happy with mine overall. But I don’t like it shifting to 4th gear as soon as it does.

Is there an adjustment that can be made?

I would like to know too! The only solution I found is driving in “manual” mode. I swapped my chip (Steve Wong I think) and didn’t see the difference.

 

What year is your car?
94/95 have just 5 possible programs as the newer ones should have a couple of tens of possibilities.

Adjustment can be made through your driving.

Point is that you have to drive very hard to get e,g, into the 5th program in a 95 model. It needs about 3 hard laps on the track to get there.
Than you would be surprise what the Tiptronic is capable of.
Or as suggested, drive in manual mode. But even there up shifting depends on the program your in.

As usual, i recommend to read THIS article out of Panorama.

 

Great post. Fascinating- thank you.

 

Holger3.2, wow. Excellent article. Thanks so much for posting. I think it would be hard to get to 4000 rpm in 4th gear around here, so I will experiment at something more close to a legal speed, if I can find a suitable place. Maybe try this technique at 3500, or even 3000 and see if I can force a program change.

all the best to ya

 

Check out this thread. https://rennlist.com/forums/993-foru...uestion-4.html

And repeating from the thread, Section 37 in the Diagnosis volume of the factory repair manual is a must-read for tip owners.

 

That’s a great article for a lot of topics. Anyone who tracks regularly should read that. Also fascinating how similar the description of the tip is to what we all know on the PDK. I completely agree with him - manual for the road and PDK (or whatever) for the track.

 

I have a 968 and a 993 both with Tips, not my choice but then after 6 years with the 968 I love the Tip, the 993 not so much. The Tip has a 5 mode program, and it learns as you drive. First off you have to drive the car to modify the Tip programming, if you drive it around town in D, with slow starts and stops it goes into "Slug Mode" shifts into 4th at 40 mph. Do a few quick stabs of the accelerator and brakes as on a curvy back roads an it might up grade to (#3-4) semi sport mode. Do a few full throttle bursts and the hard braking and repeat as you might on a track, it can go to into 5th mode. It takes some experimenting but once you find the right road and speed you will be amazed how it changes the way it shirts. Yes, I do use 3rd for most driving except for highway, the 968 has so much better torque than the 993, it's easy to enjoy in all driving conditions, plus water cooling doesn't need the higher rpms as the 993.
Being that we live just south of San Jose CA, and the traffic can be horrible a tip really makes driving so much easier. Plus anybody can drive it, if friends or the kids want to come on a Porsche drive we give them the 968 without concerns of their abilities. Yet, 1 minutes away from the garage we have an abundance of fun backroads, that require sport modes, that is where the fun begins, yes a 6 speed would be nice, bur overall the Tip fits well.
I have searched for up grades on the programing of the Tip and came up empty. Just kept serviced and drive it, and learn how to train the modes.

 

Steven, that was really helpful. Thank you.

all the best

 

I drive mine on 3rd gear for street driving and switch to 4th when I get on the freeway

 

I'll repeat ... Section 37 in the Diagnosis volume of the factory repair manual is a must-read for tip owners. The shift map selection is based on several input parameters all described in the manual. Some of those inputs are throttle position, throttle change rate, lateral acceleration (yes, there's a lateral accelerometer in the car). The default shift map is Economy which is quite sluggish and why many tip drivers use manual mode or 2, 3. If the throttle is pushed quickly past a point (halfway, three quarters? I forget) a sport map will be selected. Then if it is driven conservatively for a few minutes it goes back to Economy. Read the description in the manual and enjoy what a competent transmission it is. If it only had a couple more ratios!

 

Hoggel, any chance you could share a link to that manual verbiage and/or share the text with us?

Thanks.

 

I have only driven my Tip in automatic mode once and that was an accident.

Just my 2 cents. But does anyone notice that the tip drives way better when you disconnect the battery for a while?
I notice this all the time - but then it goes back into standard mode after a session of driving.

With paddles the tip becomes more engaging to drive.
I use to use Lube-guard fluid but now use Mobil1 Dex6.
Shifting is great. Still trying to find time to change change out the stock/worn transmission mounts.

Other performance/strength things I have looked into are from Ashcroft Transmission in England.
The ZF4HP box is so popular with other cars - landrovers, bmw, etc. Internals can be changed for better strength.

Robert's America GS over on the 964 sticky threads has some special programing from Porsche.
If only we could get Robert to let us copy the ecu from the tip box. Perhaps we should all ask him nicely.
