I Need to replace the motor in my 07 crown Police .can I use a 08 motor ?

Some of the bolt ons like the compressor may not fit for example on that type of a job. Make sure the modifications can be made and yes the computer goes with the engine and each time you disconnect or depleat a battery, the computer needs to be reset for the idle adjustment and the shift timing. There is a procedure for this - that will be the last thing you do before you drive it.

engine will work. no need to swap computer due to civilian cars have pats that will be different.
