    I think I just search for the pin now.

    Should there be 2.5V DC coming from ECM to Sensor?

    The problem with the power is related to your vehicle speed. I am running an LTG crate engine on and engine dyno so there is no vehicle. I had the same problem of loosing power around 2700 rpm. For me I input a signal into the vss conector using a function generator. The signal should be 5 volts. If you can find a way to input a 5 volt digital signal into the ecu you can then change the pulses per rev to set a vehicle speed.
