Motronic Reset?

I put a new battery in my '86 911 Carrera recently and was wondering if there is a reset procedure for the Motronic ecu? I have a '92 Ferrari 348TS with two Motronic ECU's from the same era and every time you use the factory battery cut-off switch or unhook the battery you must let the car run without touching anything until the radiator fans kick on. It states in the factory service manual that the ecu has to reset it's parameters this way. I've never heard about doing this with a 911, but was wondering if anybody else has? The 911 fired up fine and I let i warm up a while for the hell of it without touching anything.
