What is the Anti Theft?
Anti Theft is a function found on SPS2 and SPS3 that will lock out all inputs to the ECU. It will leave the car totally inoperable even if the thief has the key. Unlike other security devices this has no wires and cannot be defeated without the correct SPS unit for your specific car. Even replacing the ECU will not override the Anti Theft. Unlike the program switching, the Anti Theft function will not operate between different cars.
