Just came across this app that allows you to setup your next pitstop parameters (tyres, fuel, etc) before you enter the pit lane. (i.e. while waiting for the lights to go green or while driving along a long straight) - potentially saving you up to 10 seconds off your stop.

If you know about or come across any other useful apps for AC drop a line in here.
