Irony only shows one thing, does it?
And I'm sorry to tell you but this comparison:
why did u get a new map for ur 147? u could "teach" ur ECU to perform better.
... is just silly.
You really don't have a clue about ecu maps are and their work, do you? Or you just kidding.
Maybe it's time for you to read something about it. Marco... no one talked about that mate, only you.
One things doesn't have anything to do with the other.
Anyway, indeed the ecu gets the data from sensors (and evaluates the external and internal conditions) and also gets data from you're driving style (rpm/throttle position and so on). That data is stored in a different memory (volatile). And that's also why that disconnecting the battery you'll lose all the data (radio code/trip comp/internal and external conditions variables...).
The next time you start your car, it will start from 0 and will have to acquire all the new data from dozens of sensors. The problem is that, apparently it will work fine (and it will) in a compromised way. But it will take some time to acquire in what different conditions and style you're driving now. Would this be the faster way? Who knows... would this be the only way? Of course not!!!! And that's where the reset myth is
Tell me if you also find odd that a Sportronic gear box (on a 166) learns how you drive... cause it really learns.
It's something called self adaptive, it continually adapts to the driving style and type of route in order to determine the desired gear and gear change characteristics. This also works in conjunction with the ECU.
Our ecu's are auto adaptive to a thousand of variables. Any changes (environmental or driving) will be acquired and used to take the best performance from the engine. So, it learns (from the acquired data) and reacts according to that changes. I don't think this is difficult to understand.
