2007 g35 coupe. after resetting the ecu, how long does it take to relearn my driving habits?

 

The fact that it does, should be your only concern! How long would depend on how far you drive, but it never stops learning!

ECU resets do not relearn your driving habits, it relearns how much fuel and timing to add based on the exact parameters delivered to it by its sensors.

 

Your driving habits have nothing to do with how the Computer trims fuel, this is a huge misconception that still exists for some reason similar to how people used to think that once you switch to synthetic oil you could never switch back to conventional...

 

or are you talking about the drive cycle? are you by chance trying to get a smog test?
