The engine seems to run at normal temperature, according to the gauge. The odd thing is how the electric fan kicks in at cold temps. I don’t know anything about the software for the fuel control unit. Is it supposed be updated frequently? and what does that have to do with the cooling system? The engine is very clean, no oil anywhere. Thanks alot for your input.
