Retrofitting Sport Chrono

[tmc]

I have a confession to make: I miss the SPORT button on my M3. Sure it only remapped the accelerator that, if you just added a thicker heel to your shoe or something, would have the same effect. But it was like waking the car up when you pressed that button.

I bought my 987S right off the lot, and it didn't have Sport Chrono. How weird of Porsche to tie the chrono functions to the accelerator remap SPORT button.

Ok, my question: does the Sport Chrono(/Plus) package merely turn on firmware that's already there in the car? Is there just a connector for the SPORT button behind the center where one could tap in and make a homegrown SPORT button? Or is there a separate control unit missing? If the latter, can it be bought and installed?

I guess I'm more interested in the SPORT button itself than mounting a fully-functional chrono to my dash.

I had a short discussin with THE mechanic at my dealer about this. We thought that theoretically it should be possible to retrofit. I think without the wart as well. Might be a little pricey but it's all $$$ and adding the electronics IMO. Just exaclty how to do it is the question.

Interesting, possible is good.

Is there anyone out there with a 987 service manual who can read out the parts that are connected to the Sport Chrono system? Dsumners, if you're game, I'm game for trying to figure this out together!
