Enjoys the Abuse
1) park car with e-brake applied, car in neutral, engine running.
2) throw toggle switch to tell system to take over ignition.
3) turn off key, remove it (engine is still running)
4) exit vehicle, arm security, turn off engine from remote
My buddy has an MTX Integra, and this is how his is set up, although he doesn't have to turn a toggle switch IIRC. He just removes the key, gets out, and when he locks the car with the fob, the car shuts off.
