Hi Kikemec, the box is manual, I tell you: everything I put new: the refrigerant temperature sensor, the passage actuator, the lamdba probe, the spark plugs, the spark plug wires, the air filter (it is original), yesterday verifies the tuning with the strobe light and was very past of the 10 ° mark where it should be, it should be a little. I will test all week, disconnect battery 16 sec. I connected it again and left it regulating 15 min to accommodate only as the manual says. The engine temperature indicator is the hot engine always indicates with the needle always in the middle, whether this walking in city or route, that catches my attention, in other cars on the route I always saw the lowest indications.
