Mass flow sensor?

hi last year I croosed my battery burn the ecu and the mass flow sensor car hesitated. so I went to a junk yard and got a new ecu one mass flow. that didn't fix the problem so I got a another mass flow.. and didn't fix the problem.. now I called mitsubishi dealer and learned that the mass flow the game me is for a galant. not for an eclipse . mine suppost two have a md183609. the one they game is e5t0071 or something like that.. now they look the same and fit perfect.. they go differnt numbers.
so my question is

is the galant mass flow the same as the for a 97 mitsubishi 2.4l .. or should I purchase another mass flow.
i have to fix that hesetation problem. thanks

That sensor is sending a message to the computer that isn't right because despite of the look the sensor has GOT TO BE THE RIGHT ONE get the right one and reset the computer you can not do this go to a dealer or a good shop
