msp ECU

hey i need some help again. i just bough a mazdaspeed ecu from ebay, i'm assuming its an msp because the seller had other msp parts such as wiring harness, intercooler, and the lot (no turbo/mani :( ). newayz is there anyway to check the ecu once it gets here to make sure its a mazdaspeed that way if its not i can take it up w/ ebay for a non matching product description????
