OK so am running a 95 civic ex body harness & engine harness with a chipped p28 on a 96 JDM ITR engine & my VTEC won't seem to engage. I check the oil level & its good. I check the connections at the ECU & they are good. All sensors are connected in there designed places according to the color going from the computer to the sensors them themselves. What else should i check??? And BTW the JDM ITR does not have a oil pressure sensor by the VTEC Solenoid. Both wires from the ECU are together going to the VTEC solenoid. I had it like that before I took out my harness and it worked perfect, not sure whats missing now. And well if I can't get it to work automatically, how do I hook it up manually?
