I'm hoping to install the Perfect Power SMT6 within the next few weeks. Maybe this Sunday if Im lucky. I should be able to wire it up in a similar way to the diagram below and then monitor the pulses sent to the injector (which is not installed).
I will soon have a wide-band O2 sensor (for the option lambda input) thanks to pk2. According to by Bentley book, pin 44 of the 5.2.2 88-pin ECU connector is the throttle position sensor so that should be easy enough. Then there is the RPM input which I think should be ECU pin 80. Im not sure about the correct wiring for the other inputs though. Does anyone know what should be connected to the AMP input? I think its manifold pressure. Is there a wire from the ECU to the mass-airflow sensor that should be used? Maybe ECU pin 47? Or is it going to be from the output of my digital boost gauge (not installed yet)?
Perfect Power sent me a diagram but Im pretty sure its incorrect as it refers to a 55-pin connector and the book says a '99 Boxster uses DME 5.2.2 which is 88-pins.
