I had not driven my car for the last 3 months , until yesterday. Over this period the battery went completely flat several times . Now the boost only goes to 1.1 bar, whereas before it used to peak at 1.5 bar . Does the car take time to re learn or do i need to get it remapped again.

Thanks

 

The car will relearn but it could be detecting some det and correcting, fuel does actually go off over time.
May be better on your next tank of the good stuff.
