Ok So i have a 99 honda civic dx (d16y7) awhile back I did a head swap and put on a y8 head and y8 intake manifold and swaped the ecu also. Recently I just put the y7 head and intake mani back on to sell or tradein in the next month or two. Everything is done but switcing back to the stock ecu.. Should everything work out or is there something you need to do when puting the stock ecu back on?
