Hey All,
I'm working on a solution for a certain large, square German vehicle and wanted to bounce this off of the electronics gurus. Might also be helpful down the road for those who might want to do a tiptronic Boxster trans in their 914s. So...the challenge for me is that there are only a couple of automatic transmissions that are pointed in the right direction to use in the Vanagon and only one that can handle more than ~150 hp for a significant period of time. That would be the 911 tiptronic. My initial thought was to use a 964/993 trans which does not have a key driven immobilizer. Looking through the wiring diagrams I THINK I can figure out a way to run it with the stock TCU. But then I found the Megashift trans controller: Megashift! IF (big if) I am reading the directions right, it appears you need the shift solenoid configuration (probably more stuff too), and then it should be fairly easy to control. So the questions are: 1. How easy/hard do you think this would be? Seems like you program the solenoid shift config for each gear, kick down, a few other settings like idle increase, etc? 2. Since the security logic for the immobilizer is not associated with the trans itself, do you think this fully bypasses the immobilizer? Seems like it but I know very little about the tiptronic box. 3. Is there another stock automatic TCU from a VW or Audi that could be adapted to run this? EDIT: The Passat TCU MIGHT WORK. Same trans model #...ZF5HP19...

I'll give it a shot if the feedback is good. |
