How to Upgrade Car ECU Chip?

Want to get more power and better fuel economy from your vehicle? ECU remapping is the effective choice for improving your car performance because it creates a brand-new map that adjusts how the engine works and is designed specifically for your vehicle, with all its individual components taken into account.

What is ECU?

The ECU used to only control the fuel mixture, but they’ve progressed over the years. Modern ECUs are little computers that gather data from sensors all around the car, including wheel speed sensors, O2 sensors, temperature sensors, and engine sensors. ECUs interpret all this information to control everything from throttle position and ignition timing to variable valve timing and your vehicle’s top speed.

What is needed to upgrade an ECU?

Upgrade an ECU is performed by writing a new software program onto electronic control unit (ECU). This is a relatively simple method of tuning, usually done by plugging a laptop into the car's OBD port (the same plug most garages use to diagnose a problem with your car if it breaks down.) However, this requires professional skills and a good ECU Programmer, such as SM2 PRO J2534 VCI Programmer


How to Upgrade Car ECU Chip?

It depends on the type of modifications and the type of engine. For example, changing an intake manifold on a turbocharged engine could have more impact than on an atmospheric engine. More oxygen mixed with more fuel results in more power. But for this to be true, the ECU must be reprogrammed so that it sends the right amount of fuel depending on the amount of air that the new modification brings. Correctly tuning your ECU to fit your new mods will protect your investment and will also make your car go faster.

Here are some examples and the tuning required for the control unit to be compatible with the new setup.

1. Supercharging

The engine will have a hard time to run at idle, start when cold, and produce enough power in hot weather. It’s also required to change the opening time of the new injectors. As the original ECU was calibrated for smaller injectors, the amount of fuel sent by the new injectors will be too large for the same injection time. Nonetheless, it will be necessary to change the ignition time. The new air/fuel mixture will be denser and more heat will be produced by compression, the ignition time delay will also need to be adjusted to avoid early detonation.

2. High revs

You will need to program your ECU if you change your cylinder head to take advantage of more aggressive cams and want to push the rev limit of your ECU even further.

3. Camshaft replacement

In most cases, it is possible to keep most sensors and OEM injectors for this type of modification. However, adjusting the injection time will be required. The ignition timing and atmospheric correction factors will not be affected by this particular modification as much as when supercharging an N/A vehicle.

4. Nitrous oxide

Some nitrous oxide kits come with the necessary parts to increase the amount of fuel sent to the engine without having to reprogram the ECU.

5.Provides your car with a compatible drive

Different car drivers need different types of drives according to their geographic locations. Upgrade ECU Chip for your car will gives you that perfect driving experience.

After the completion of an ECU Upgrade remapping of your car, the performance of your car will improve in various ways.And this is great for improving your vehicle’s fuel efficiency.
