I'm very happy I chose a Tip. Nothing to do with shift profiles, but the biggest improvement in shift smoothness I experienced was from changing my 23 year old engine mounts. Remarkable difference: https://rennlist.com/forums/993-foru...wners-too.html
What would people be willing to pay for something like, "Permits Driver To Hold Transmission In Gear In "Tip" Mode – Transmission Will Not Override Driver" ?
One of my favorite Tip videos. I think this guy definitely got his transmission into stage 5. Love the hands on wheel up shifts at max rpm! (pay no attention to the cover shot - it's not just a FS ad.)
There may be potential here for anyone serious about this topic. It took me a while to re-locate the link but I ran across this company right after I bought my Tip. The interesting thing is that they make a version for our transmissions, (as installed in Land Rovers and BMW's.) I was going to contact them to see if it could be adapted but lost steam. In any case, it looks like solidly engineered kit and it would be interesting to see if this might work on our cars.
hogged, thanks for posting this. However, I read section 37 and didn't see much in the way of guidance. I did see a pic of the kick down position and noted that. I'll be in my car tomorrow and will investigate further.
I will say a big thanks for the post tho. lots of good info on other 993 subjects. Bookmarked.

Ya, probably not guidance. But it does describe how the transmission programming works. I thought pages 37-56 to 37-61 explained it all.
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.
Here is a description of his transmission: Transmission:

I will find out today. I left the engine lid ajar after checking the oil level last week and you know the rest of the story. I went to crank it up yesterday and it was dead. So dead, the door would not unlock.(0% capacity and 1.2volts) Gave it a charge yesterday and will let you know.

Can we get more info on that?
- link to the thread
- ask Robert for more details on the program
- would it work on standard tip
- etc. etc.
sounds all to good to be true
All is well. With everything going on, I have never found more pleasure and solace in just taking the old girl out for a drive. My portfolio is sucking wind but daily driving the 993 is the ultimate social distancing. Stay well my friends.
Playing with automatics in other cars I found....
Adjusting kick down cable makes the car down shift sooner vs lugging engine mid throttle.
Early TC lockup bogs engine. Tap brake pedal to see if this is part of your gripe. If so reprogram to suit your needs. I like lockup based on speed and top gear only. Absent the ability to reprogram I’d run a switch to TCU (off brake switch line) to toggle lockup on freeway only.
In this application it would be great to have the ability to switch between programs manually. Check with Todd at Protomotive and see if he’s got any options for this. He’s a REALLY sharp guy who is up to the challenge.
A small tidbit for use around town. I’ve discovered that you can just put it in third gear and it will shift through all the gears 1 through 3 from a standing start to cruising around town. Most helpful when I have to let my wife drive it for a run around town. Can’t let her cruise at 30 mph in fourth gear, can I? I suppose I could do the same with second gear, but she would be uncomfortable with the car driving at 5K RPM.
