My Chim 500 has an intermittent problem. It revs like crazy when setting off but seems to calm down after 20 minutes or so. Anyone know the likely cause?

Possibly a failing Ecu water temp sender, or the usual stepper motor fault or un metered air leak into plenum.
Try using Rovergauge to narrow down at least two of these possibilities
