alright this ecu came off of my 91 civic with a B18A and i got the right corresponding ecu for it so i dont need this one anymore... i was told by xenocron [hondaswap] that this ecu came off a 1990 integra and there seems to be a difference in the PA sensor hookup location between the two.. so yeah the top one is the one im selling since i recently just bought the bottom one from brian11to1 also from hondaswap
