Tiny consideration right here only that the computer software system, there are 3 significant computer software systems to maximize the efficiency of effect to the car, electricity, fuel, air, and a brief overview of the 3 soft automotive functionality systems, a detailed description of the many parts, for car engine functionality, is the engine Power To enhance and lower the Fuel consumption To cut down emissions to extend engine life. The engine has a lot of mileage but when we checked the compression, readings are all above 140 psi. Also, when testing the oxygen sensors for this engine, the upstream sensor is utilized for engine fuel management whereas the downstream sensor is used to monitor CAT efficiency. Very first of all, remain away from after market place parts when dealing with imported vehicle like Honda. Having said that, if I scanned it, my scanner will not communicate with the engine computer system (ecm).
