Sports Chrono - Please Help!

[TommyRS_]

Hi all,

I have a question is which I would be very grateful if you could hopefully answer it.

I am currently looking at buying a Porsche 911 C4S 997.1 (Manual)

The car is fitted with sports exhaust, PASM and also has the chrono clock on the dash which naturally would suggest it has sports Chrono.

However.... to my knowledge on this generation if it has sports exhaust and also sports chrono the interior received a “sport” button in replacement to the sports exhaust button. I’ve looked at other cars for sale and this always seems to be the case.

But this car has the sport Chrono clock, but with the exhaust button as opposed to the "Sport" button....

I was hoping you would perhaps be able to shed some light on this? I’m not aware of the Chrono clock ever being retrofitted (as where I know the sports Chrono Package can be retrofitted) and the car also has a letter of authenticity from Porsche and “Sports Chrono plus” is definitely listed.

Any help would be appreciated.

Thanks for response.

I'll do some more digging around. Sadly I'm far more knowledgeable to Gen II stuff on wards.

Good shout on the vin number. It's not a deal breaker either way as worse case scenario i know the sports Chrono software can just be retrofitted anyway.

I just find it a little odd that the Germans would accidentally produce the car with the wrong button in it.

If sport mode was retrofitted, which some dealers did, it didn't include the clock as it involved changing the dash so cheaper to sell and buy another car.

If the car you're looking at has the clock, then it should have the sport button which adapts the throttle map, turns on PSE, changes PSM interference point (allows more slip before intervention) and turns on PASM sport (very hard) mode.

Go to 'trip' on the PCM (bottom row on PCM towards right) and see if 'sports display' is an option, if it isn't then someone has just stuck the clock to the dash (!), the other way of checking is to use the computer control arm on the lower right of the steering wheel to select the lap timer. Once you start timing a lap, the clock should illuminate and the hands whizz round to zero and start timing your lap

This will tell you if someone has just stuck the clock on - very unusual.

If these options do work correctly then you have a different problem, the lower row of buttons that has sport / pse / spoiler / psm buttons, is replaceable as one unit and you have to order the one that has the corresponding options for your car. My guess is a previous owner replaced that switch panel for some reason & got the wrong one or something, maybe ordered it off ebay or something. They're probably £200 from Porsche I'd imagine for the right one but just a guess
