When I had modified the motorcycle, I installed a high-end, Bluetooth-enabled digital ECU (Engine Control Unit) that allowed me to adjust the bike's fuel mapping from my phone. It had a security feature most people didn't know about.
The bike was already a quarter-mile away, but it had to pass through a major intersection at the bottom of the hill. I ran toward the edge of the lot, looking down the hill. I could see my bike waiting at a red light.
I tapped the screen: [EMERGENCY ENGINE DISABLE].
The app sent a cellular kill-command through the bike's GPS anti-theft module. Instantly, the motorcycle's engine died, locking the rear wheel.
At that exact moment, a police cruiser happened to be crossing the intersection. The officer saw a man in a tinted helmet frantically trying to push-start a high-end sportbike that had randomly died in the middle of traffic. When the thief saw the cruiser and tried to drop the bike and run on foot, the officer tackled him.
I walked down the hill, phone in hand, to find the thief in handcuffs and my bike completely unharmed.
