ENGINE TUNING IS IMPORTANT

Do you know that engine tuning is very important? Especially when your engine performance and efficiency deteriorating. The tuning process will include the use of special device plugged in to your car and ECU tuning is achieved through the device. Some of the device is called OBD and MUT. You can buy it online with the price of around rm1000 or just going to the local workshop and ask for engine tuning for better fuel efficiency and performance with only rm35 of car engine tuning charge.

Setting the idle speed, fuel/air mixture, carburetor balance, spark plug and distributor point gaps, and ignition timing were regular maintenance items for all older engines and the final but essential steps in setting up a racing engine. On modern engines, equipped with electronic ignition and fuel injection, some or all of these tasks are automated, although they still require periodic calibration.
