You have a nasty gremlin on your hands. Becareful grounding black wires by the ecu; not all of them needs to be grounded. I personally have never experienced a problem such as the on you're having, but if you have someone near you that sports the same engine swap, see if they would let you test the ecu I sent you to see if you haven't smoked it already. Your problem lies within the wiring that you wired and it's probably something as simple as a wire being hooked-up wrong. Take your time with this man and don't be too proud to go back through the work you've done already. Good luck..........
