The ScanGaugeII will read it. Mine runs over 800 at idle and about 1600 under a load. Have seen over 1900. Some things that the ScanGaugeII is suppose to read does not work on mine.
Maybe the firmware will get updated so that you can read it on the Gryphon. Call Edge and tell the it works on the ScanGaugeII and tell them to get on the ball.
