On the Mustang, bank 1 is the right side (cylinders 1-4). Bank 2 is the engine left side (cylinders 5-8).
The front O2 sensors are responsible for engine management. The rear O2 sensors check the operation of the cats.
The O2 sensors to disable are the REAR O2 sensors. Sometimes referred to as 1-2 and 2-2 (first number is the bank (right/left), second number is 1 for front, 2 for rear).
There should be a MIL option, and just turn that off. All other o2 options are for such things as turning OBD2 monitoring off, the heater cycles for the sensors and so on.
yeah but if i turn the mil off, then the light wont come on for other problems that may happen.
also if i have all the 02 sensor options on the diablo off, will that screw up the front o2 saen sensors? because that would cause problems if there shut off.
