p6? pm6? yes you can, but in my own opnion it doesn't run like it should. Vtec engagment is false and doesn't get the power the motor should get from the ecu. Because the ecu is what gives the motor more fuel and all the actavator does is actavate the solnoid. Missing power. The a6 manifold that is the SI intake manifold right? You can, but you can use the y8. The only thing is, the y8 won't have a IAT sensor location. Then you will have a code 10? I think thats the correct one. Unless you drill into your y8 manifold I guess and run a tap through it and put that sensor in the manifold which is what I was think of doing when I was runing the si ecu.

I would switch over to obd 1.
