i have a 96 civic hatch. my motor just recently blew and i put the d16y8 in but i have my old d16y7 ecu still in it. the car i bought the motor out of was an auto and i put my 5 speed tranny on it. i was wondering if i could use the ecu out of the old car on mine. even though it was an auto. i would hate to buy another ecu and find out that i could have used the one that i already have.
