    right I've put a d16z6 into my black facelift Civic which is obd2b 

    the loom im using is the d14 obd2b 

    ECU is the p28 with the conversion harness

    hardwiring VTEC in

    Dizzy was a d16z6 then put all d14 obd2b internals inside the dizzy

    put the car in for MOT today and it failed on emissions big time they also said about the fact its running rich?

    What can i do to get it running correctly? im really running out of ideas I've been told i don't need to worry about the crank sensor, the dizzy has been nothing but a pain im on the verge of selling this or breaking it 

    I've not had much luck on here tbh but its worth a shot

    might be worth trying a different o2 sensor, if there bad or not wired right the emissions go up by alot

    try that too mate.

    xanavi did you hardwire the VTEC in from the solenoid to the ECU and the back of the clocks too? im putting a d15b import engine in my facelift EK and was just looking for some advice or troubles that you may have run into when doing this swap. As the D15B swap is basically the same as D16z6 swap...both obd1
