Hi fellows, I had just recieved an JDM OBD2 integra type r ecu in replacing my JDM P72. For my knowlege, the p72 has a second stage of vtec if you would to call it, which at 5000RPM the valve butterfly open to allow more air into the intake runners. Since I am going to use a p73, this ecu has a single stage vtec, how do I disconet the valvumm line so that the butterfly will remains open wide from 1000RPM and up? Do I have to disconect the wires that hook up to the wireharness for my p72 second stage of vtec since I am going to use a single stage of vtec??? thanks for the helps
