Anyone have any experience with converting the mechanical throttle linkage on a 911 with an electronic servo system?

My next project....

No, but I can't see a problem, A Search for control circuits for a servo found http://www.epanorama.net/circuits/servo10v.html

I'd be more worried about how it faided though, with the mechanical systems, they mostly fail to closed, a servo losing
power will simply stop, a worst case is that it went berserk

I think the Motec ECU's can deal with them. You really need to be carefull just doing something home made in this area. As Neven said, "worst case is that it went berserk". That would not be good. I thought about this option as I have a Motec M600 on the shelf. The more I thought about it the more I liked the old method.

I don't see why anyone would want to do this. The response will always be slower than a mechanical linkage.

I am exploring the idea of throttle servo because my new ECU can accomodate it. Some of the newer cars have drive by wire. I suppose it depends on how fast the servo is. Also, if it does not have to move much mass a servo might work well in most cases.

It would be really cool to tie this into the tracktion control system. It would make our old cars handle like the new ones.

what benefit do you expect? does your new ECU have traction control? is it a commercial ECU or a grassroots ecu like MegaSquirt?

why?? steer by wire would be more interesting. how lucky do you feel?

yes, you could hook it up to a microsoft force-feedback joystick! and hope for no driver bugs!

And since there aren't any good drivers for 2000 or XP, your car would be tied to 95 or 98.

*shudder*

I too ask why since a lot of the fun in owning a 930 is controlling the traction with your feet.

Agreed - this is a solution looking for a problem...
