I bought a '91 Civic Hatch with the B16A in it and it came with a Mugen Chipped ECU. The motor is pretty much stock except for a 4-2-1 header and an intake. Is the ECU even worth haveing? I burn up so much fuel and my plugs keep going out. I was told it dumps in around %20 too much fuel. Should i buy different plugs to burn up the fuel or just get a stock ECU from a GSR or ITR? What would u guys do?
