Anybody know about this? I am planning to install Greddy Emanage or SAFC to my car since I've BOT my engine and I got complete wiring diagram of my car but I don't know whick one to pick up. This are the sensors I've found: knock sensor, o2 sensor, combine MAP/MAT sensor, camshaft angle sensor, crankshaft angle sensor, ignition system, throttle position sensor and all 4 injectors. I can't find RPM signal wire to the ECU. Fot those who know about it, please inform me. Thanks in advance.
