"..The ecu will adapt to your driving habits.."
And here I thought Porsche owners were too bright to believe that CRAP..!!
Maybe in the general case.
Even if the ECU does "learn", adapt, to some aspects of your driving habits those will be, MUST, be erased upon each engine stop/start cycle.

I'm guessing this is this to decrease drag on the motor, and help keep revs up when shifting???

huh? So, when you put an exhaust or a cai... the ecu wont know the diff between aftermarket or stock?
Not immediately, not unless you "tell" it.
The engine management on these cars are adaptive... just about any modern sports cars have this feature. When you unplug the battery, ("telling" it") the mapping goes to default... as you drive... the car learns your driving habits.
No, it learns new engine/sensor/control mapping parameters while you drive, based on how you drive, NOT YOUR driving habits.
In other words... it re-maps itself based on trending patterns of the way you drive.
Once a parameter is "mapped" it will not be re-learned in accordance with ANYONE's driving habits. Excluding driver unique parameters that are ERASED upon each stop/start cycle, MUST be erased.

Modify the engine in some manner and the ECU will eventually learn new parameters if/as needed. Or you can disconnect the battery for a period and the ECU will adapt to the "new" parameters more quickly.

Walk to the front of your car. Bend down and look into the big opening in the middle. If the opening is actually open and you see a radiator grille in there, then you have the third radiator (the other two radiators can be seen with a flashlight by lookng onto far corners of the front openings). If you see black plastic, or nothing but the outside of the truck well, then you DO NOT have the third radiator. Most C2 manual shift cars DO NOT. All GT3, and Tiptronic C2/C4 (should) have them. C2S/C4S may have it, depending on year.

Another thing.... The driver's side rear fog light is operable but the passenger side rear fog light does not illuminate. It comes that way from the factory.

True if the original engine. All M96/01, M96/02 and M96/04 replacement engines from Porsche have a Tip harness installed and the sprag type pulley. Therefore, the replacement engine can be used in either a Tip or a manual car. The freewheeling pulley was to fix a belt shredding problem IIRC.

and if you want to get a redneck to laugh at your car because it has "electrical problems" just drive in front of your brother with that on and he will be happy to do that for you......
Then explain that it is "normal" and you did that on purpose to see what he would say and it will confuse the sh^t out of him as he will again explain that something is wrong with your lights.....

I've been playing with that climatronic diagnostic. Super cool stuff. It's fun to watch the coolant temp (6c, I believe) get up to 87 degrees, then drop down a few as the thermostat opens, then climb up into the 90s.
We'll have to figure out what some of the "unknown" codes are.

That a CEL on the 996 is usually FI/sensors related whereas other cars I've owned were always polution emissions related. This caused me not to diagnose for 55k miles thinking, "ah, its ok", when the whole time the MAF had croaked.
Bosch electronics..........Germans cant make anything electrical worth a crap and plastic for that matter!
Relax, I'm kraut.
