Knock sensor

Is it possible to add a knock sensor into my 2001 Mustang GT Convertible? I want to add the predator tune which does require 91 octane but I just wanted to prepare for the worst case scenario such as someone in my family taking out the car and fills up the tank with 87 octane, or an even more bizarre scenario such as the gas station filling up their storage tanks with the wrong octane.

Thanks for the information and link

Do you know if this device will also compensate for lower octane?

For example, a Lexus vehicle that requires the use of 91 octane has a knock sensor in it so that just incase 87 octane has been put in, the knock sensor and engine compensates for it to protect the engine from horrible damage, but at the loss of power from the vehicle.

A cobra's ECU uses pins 57, 32, 102, 23 for the knock sensors. If there's no wires you would have to run them yourself. You have to ask the guys at SCT if they can make a custom program for you that pulls timing when knocks are detected. Here's a wiring diagram for the knock sensors for a 2001 cobra. http://www.geocities.com/joop1987/knock.jpg
