yesterday i unplugged my ecu from my conversion harness and the conversion harness from the engine harness. i then tested another ecu with a type-r base map, i have a B18cR. the car ran like **** for some reason, so i put my original ecu in the car and the now my car still runs like **** even tho i put in my ecu (which i did nothing to). i'm now thinking its the wiring on either the conversion harness or the engine but what wires could cause the car to start, low idle, then bog, then die?
