first off, what year is your car ? and what year/type of ecu is it suppose to be?
have you removed the ecu cover at all?
if you have removed the cover, see if there's a secondary board on it, as seen here:
if you see this board (knock sensor board), this means the ecu is a genuine DOHC VTEC ecu.
if it doesn't have that board, look for the black transistors pointed out in the '5-speed' section of this image:
if it has those transistors, then it is a VTEC ecu for sure.
