    Everything you ever wanted to know about the AW4

    Given the apparent simplicity of control parameters, this has been my conclusion also. Manifold pressure, RPM, and coolant temperature COULD be used as modifying parameters, although there does not seem to be any documentation of that. Throttle position, via TPS voltage, is a direct input.
