You don't want your fans running during a pass anyway. They actually tend to block air flow through the radiator. They can not move as much air as ram air above 40 MPH or so. Factory computers cut the fans off about that speed and just let them "wind mill". I don't know about other ECUs, but FAST cuts them off at WOT for the same reason. The car will actually run cooler that way, they will come back on in the shut down area. Art, you might check with the people that make the ECU you are using about that.
