"BTW, the Regina IAC has a constant +12V supplied but is grounded in a step function through the ECU, hence is able to control the idle."

As I posted below, the Bosch LH 2.4 IAC circuit appears identical to the Regina, right down to IAC pins, wire colors, and ECU pins. Perhaps the FAQ regarding non-interchangability, that Invar mentions, needs to be updated?
