Gonna swap a jdm d15b into my 92 civic vx, I'm going to use the vx harness but the vx o2 sensor has 5 wires and the d15b has 4 wires, also what would be the best ecu? Thanks!

 

Don't make separate threads. Ecu for the D15b7 is P06, if its a JDM D15b you need a p28

 

Thanks for the input I'm going to get a p28 with maybe with Neptune, but stock for now, my only concern is going from 5wire o2 to 4 wire? Is this difficult? Also if I use the vx ecu will the vtec engauge right because the vx is vtec e.thanks for all the help!
