I have used the advanced search to find an answer to no avail, so here is my question.

I will be mounting a new winter wheel set next month that includes new sensors. I already know that the sensors/ECU will have to be initialized so that the ECU recognizes the new sensors.
Question; Next spring, when the summer wheel set returns to the car, will the ECU have to be initialized again or will it remember the previously mounted sensors?
2nd Question; Likewise, when the winter wheels are mounted again the following year, but rotated (front to back, back to front) will this mess up the ECU with the need to have the ECU initialized again?
Anybody been there done that?
TIA
