2. The Engine Control Module(ECM) of a car is a computer that controls the key functions of your engine.

3. By attaching a chip tuner or performance chip into the system, the parameters in the computer can be altered.

4. Such alteration in the settings can result in a change of key factors in the engine such as the air-fuel ratio and the spark timing.

5. When you opt for engine control module tuning, then it has both positive and negative effects which are discussed below.

6. More power More efficiency Affordable upgrades 1 2 3 Positive effects

7. More power

8. The car manufacturers tend to be conservative with the settings on their ECM to account for changes in elevation, temperature, fuel, and maintenance schedules.

9. Chip tuning can change the settings to get more power from the engine, adding a good chunk of horsepower to the car.

10. More efficiency

11. The main goal of chip tuning for a long time was power, but today’s higher fuel prices and environmental goals have changed that.

12. Modern chip tuning can help your engine run more efficiently, and help you to get more mileage.

13. Affordable upgrades

14. When you think of buying custom car parts, then only you realize how much they can cost to get installed.

15. And in contrast, getting the chip tuned by a professional is much cheaper and that too with great results.

16. More wear More mistakes More maintenance 1 2 3 Negative effects

17. More wear

18. That extra horsepower attained by the car translates to more force and generates excess heat.

19. All these force, heat, and revolutions result in a lot more wear of the other parts of the car and also puts stress on your engine.

20. More mistakes

21. It might seem like chip tuning is as simple as plugging the chip into the right port, but in reality, it's more complicated than that.

22. Use of wrong chip or the wrong chip settings can easily cause your engine to seize up or break down and the damage is often irreparable.

23. More maintenance

24. One of the big reasons manufacturers are so conservative with their chip settings is that they expect people to perform infrequent maintenance.

25. When your engine has a chip tuner installed, you’ll need to make sure that you perform more rigorous maintenance, and also use the right kind of fuel.

26. Lastly

27. Remember that, going for better replacements parts will definitely help you get the most out of your chip tuning.

28. It is something to take into account since many people who get chip tuners are planning to customize their ride anyway.
