HOW DOES EFFUEL WORK FOR FUEL OPTIMIZATION? IN INDIA

No it does not. It only affects the mapping of the Effuel for the duration that it is connected. Once you remove it from the OBD2 port, the ECU switches back to its factory mapping as if nothing happened. This is why it will not void your car’s warranty.There is no one stopping you from doing so and there is no harm in it as a mechanic can do a similar job manually. However, keep in mind that the remapping performed by a mechanic is permanent and it can prove to be expensive as they charge a lot for this. With this device, the change is temporary (for as long as you like) and it is affordable for everyone.Click Here https://www.globenewswire.com/news-release/2021/04/12/2208677/0/en/Effuel-Reviews-2021-Effuel-Eco-OBD2-Device-Fuel-Saver-Chip-for-Sale-By-iExponet.html https://sites.google.com/view/effuel-web/home https://gocrowdera.com/US/other/effuelecoobd2/
