Natalya makes a small PCB which feeds the ECU a ~2mph signal for a moment, which causes auto-stop to kick in at any speed, and doesn't affect the FCD (because it calculates MPG and shows speed without the ECU). It will stay in auto-stop until you throw the car back into gear. Just put it on a relay with a button near your shifter and you have auto-stop whenever you'd like.
