F4 EMS GEN 2

Ever stranded by the side of the road with an overheated engine? Or sudden hole through the hood of your car because the engine decided it did not want that crucial part there? That happens when it gets too hot or cold in the engine. And because the car is old it does not know these values. It only knows it is there or if it isn’t there.
Oil for example, the normally syrupy liquid in the engine at higher temperature becomes water like. At which point it will not lubricate anymore. Or a hole in the engine appears, and oil vanishes. An Engine Management system lets you check how the engine is doing and warn you if it gets too hot! Too hot = Bad. Too few = very bad. Too much? Extra oil for rust prevention!
