    I have a 93 honda civic dx. I just swaped a b18b engine from a 96 acura integra. and I made the auto to manual conversion aswell.....Now. I ran the stock ecu for 1 day and it was running good...Next day It started boggin down on me...since the 96 integra ls engine is an obd2 i had to do the obd1 to obd2 conversion....Now im running the stock 96 ecu.....The car starts and all but its misfiring a lot.... Theres a lot of smoke coming from the muffler..(Black smoke) I change the spark plug wires and the plugs. still the same....I took apart the throttle body and the intake was dirty....It looked like Black oil or something....It does this with both of the ecus.........whyyyyyyyyyyy?

    question...s...

    do you think is the o2 sensor?
    ignition timing....?
    what the fu-- could it be......


    I know the engine was good because it was in my buddies acura and he used to drive it....It only has 97,000 miles on it.....

    Thanks....

    from what i understand the gsr is not turbo friendly unless you are going to work on the internals, the b18b is not working, maybe because you are using the obd2 ecu use your stock obd1 ecu see how it runs if it runs even a little better get yourself a chipped ecu that can feed the engine the fuel it needs so it doesn't run lean and you should be good from there and shyt if you not going to use the b18b block pack it up and shipping to pa for me i will fix it no promises of shipping it back...lol good luck

    code 54 is crankshaft fluctuation sensor intermittant interuption, or crankshaft fluctuation sensor no signal.
    The ecu uses the ckf signal to measure changes in the rotational speed of the crank. If the speed changes exceed a set limit, the ecu concludes that misfires have occurred.
    It's located on the timing belt end of the engine, down by the crank pulley, remove the timing cover to see it.

    code 65 - secondary o2 circuit heater. Secondary o2's have no bearing on how well the engine runs in a honda, wont cause a misfire. Secondary o2's are used on 96 and newer hondas, and is only there to monitor catalytic converter efficiency.

    if I had to guess, I'd say its ignition timing.

    b18b out not running because that Crankshaft Speed Fluctuation sensor shit kept on fucking around. O well./... I just bought this guys smashed up 94 gsr with 117,000 miles on it for 2800......I went got a flatbed and towed the integra home.......first thing to come out was the engine.......---> gsr is in ....how do I setup the vtec wiring? I have the one plug with two wires left .....I was told I can plug them into the o2 sensor wires.(Black-Green)...Or should i just run them to the ecu..........what pins on ecu?..... :D


    I have a 93 honda civic........


    What times would i be running on 94 gsr with dc headers,w/ staright pipe and cold air intake.........

    How Do I post Pictures so I can show you guys my setup....... :lol:

Im getting different codes this time.....Im getting

    :ph34r: ...................codes.................. :ph34r:

    #21= VTEC Solenoid Valve Open or short in VTEC solenoid valve circuit, defective VTEC solenoid valve

    #41=Primary Heated O2 sensor heater circuit Open or short in Primary O2 sensor heater circuit, defective


    Does this have to do anything with the black smoke coming ot the exhaust...Im thinking maybe...,,,,when I did my first swap (b18b) which was last week, I went to fill up the gas tank.....I notice then that day that my car was misfiring and smoking a lot....what do you guys think.....would it hve anything to do with the gas.....
