Do I have to drive like mad after resetting my ecu?
I reset my ecu for the first time and from what I read it will be learning my driving habits for the next 200 miles. How should I drive to optimize the learning?

Here's a excerpt from a thread in the engine section describing the "learning" function of the ECU;
The point to remember is that the ECU is constantly getting updated, so driving for 200 miles like a mad man will eventually get averaged in with the 5000 mile you drive normally.
Ok, the deal with the resetting the ECU. There is a segment of memory that will get cleared out by resetting the ECU. This segment holds info for fuel mapping, airflow, etc... based on your driving style, and is continuously updated and averaged.
So, as you can probably guess, unless you floor the car from every stop, and constantly drive 100mph, that memory will eventually get populated by a descent representation of your "overall" driving style.
If you always drive conservatively, never really give it too much throttle, don't go much above the speed limit, then you will end up with a map that simulates this. On the other hand, if you always have your foot "in the gas", you will end up with a more aggressive map. If you have a conservative map, the car will seem slower to respond if you do want to get on it, and vice versa. Some people say they don't notice any change when resetting the ECU, some say it is quite noticeable, so the overall health of the vehicle comes into play here as well.

you don't need to drive like crazy if you have anytype of piggy back ECU, ie SRT or APexi. The car always see more air all the time. Why would you drive crazy to get to a more aggresive fuel map unless your plan to drive like that forever, because, if you stop driving aggressively, your car will learn back.
waste of time to pursuit this, pursuit a way to reprogram the fuel map in the car main computer, or use some type of piggy back ECU is the way to go.

That's exactly the point I was trying to make! Unless you drive 100mph like your hairs on fire 100% of the time, the ECU will eventually set itself to the "average" of you driving style. To me, the only time I could see resetting the ECU would be if you went to the track, or a meet, or a cruise... somewhere you want to have that extra uummph for a little while.
Just do it like on the 1st of every month or so.
