- Leave the car sitting for more than 10 days ...be prepared for the battery to be dead.
- If you zip tie the yellow button on the orange rectangular box above the clutch pedal on manual cars, it will improve the shifting.

The throttle map is different depending on if the clutch is in or out. Zip-tying the switch makes the throttle map the same all the time.
It seems like a lot of trouble to mess with when a little practice would do better...that being said I haven't tried it. But I don't plan to.
Okay here's one...the lug bolts have a special collar so that as you tighten or loosen them, they do not rub against the wheels and mar them up.
Also, the tip of the Porsche crest on the center cap is supposed to point towards the valve stem!

After falling in love with a Porsche, it is likely you will think all other cars look like crap ![ooops](https://rennlist.com/forums/graemlins/icon501.gif)
- good info here - I have some new things to do on the car, tried the temp control unit thing and got in some wierd "mode" I will try again later... mine said "0" and something, then I mover the up and down arrows andit went to 1-2.... I stopped... what was that ? (pressed recirc and top ^ on right for 3 seconds)

Ed, do you have this?
Porsche AC Diagnostics
(undocumented, unsupported feature)
The AC Climatronic unit is actually manufactured by Audi. There is some sort of serial data stream (not CAN) that allows the AC unit to display engine parameters. This works on 1997-2000 boxsters. Same as 996....
To switch from F to C:
Hold down the recirculating button then push both the temperature + - buttons.
To access diagnostics:
Hold down the Recirculating & Air up buttons for 5 seconds. The + - buttons go up and down through the list of "c" codes. The center vent button switches the left display between the "c" code and its actual value. Press the Auto button to exit.
I have yet to verify all these, this info was copied from wonderful people on PPBB!
Here is a list of what can be seen:
0c - ERL
1c - Oil Temp?
2c - Inside temp. Sensor mounted in the aspirator assembly at the side of the dash.
3c - Outside temp. Sensor located inside the air inlet of the A/C unit.
4c - Outside temp. Sensor located in front grill of the radiator. The data is fed to the Climatronic from the instrument cluster. When not moving, the instrument cluster OBC temp display retains it's last setting until moving. This is to prevent heat emanating from the radiator affecting the temperature sensor. The A/C unit uses the lower of the two outside air temp values in determining fresh-air temp.
5c - Outside temp. (matches OBC outside temp display)
6c - Coolant temp.
7c - Footwell discharge temp.
8c - Sun sensor (dash top)
9c - Sun sensor.
10c - Passenger compartment fan speed.
11c - Passenger compartment fan voltage.
12c - Temperature mix Flap command 1=COLD, 100=HOT
13c - Temperature mix Flap position
14c - Central Flap command
15c - Central Flap position
16c - Footwell/Defrost Flap command
17c - Footwell/Defrost Flap position
18c - Recirculation Valve command 1=OFF, 100=RECIRC
19c - Recirculation Valve position (feedback)
20c - Vehicle speed in kph, updating only once per second. (real speed, not speed+safety margin as in the speedometer)
21c - Engine RPM in hundreds. This too only updates once per second.
22c - ?
23c - ?
24c - Sun sensor, exterior lights switch & panel lights control (term. 58 & 58d voltage) - used for A/C panel display illum.
25c - ?
26c - ?
27c - ?
28c - Fan speed?
29c - ?
30c - Engine run time in seconds (255 max.)(=0xff)
31c - Timing counter
32c - Displays test
33c - Software version? Mine states 3.4
34c - ?
35c - Outside temp. from inlet sensor (filtered?)
36c - temp?
This is the anti stall (when on a hill) switch... the map is slightly more aggressive so it is easier to drive forward when you are on a steep hill.
It does give it a better throttle response...
This is called a floating collar... it helps maximizing contact surface area of the lugs/wheel, centering the lugs.
This is a concourse detail thing.... this is a must!

That clutch switch is the clutch delay thinger, which actually cuts back on throttle response. I think Porsche wanted it in there so people wouldn't rip up their clutches so fast. A lot of companies do this, actually.

The little tab on the gas flap holds cord and cap away from fender.
Cab top only leaks at the car wash
Panties do not automatically come off passengers.

Some times you can get a check engine light and want to reset it to see if it comes back. Cats or air sensors could through a code. So yes it does save you a few bucks instead of getting a OBDII reader
Meant unlock, though to lock you need ignition key out.
Hitting the PB still will have the fan/heat going. If you want to completey turn off the unit do you need to hit the fan button until it says off. Also the AC/Fans stay off even after restarting the car.
