They acutally have the D15B motor in japan? Isn't that just a DX motor? And with VTEC? Check out Honda Hybrid for your wiring info.

 

cant find him..

 

 

I would recommend running a P28 ECU for the D16Z6 motor..

As for wiring VTEC. What year Civic do you have? And what wiring harness are you using for the D15B motor?

how bout a p08 ecu? is that ok to use? im using a 92-95 sohc cx wiring harness.

 

If I remember right, the P08 ECU is the D15B factory ECU correct? If that is the case, it will run just fine.

As for using the CX wiring harness, wiring for VTEC you need to wire from the VTEC solenoid to the A4 pinout at the ECU.

VTEC pressure sensor from the sensor to the D6 pinout. And VTEC pressure ground to the thermostat housing ground held on by a 10mm bolt. This is the engine harness ground.
