Time will tell as one has to wait till 2021 end to see whether these issues are being repeated or not if a person is more skeptical. Otherwise the 3 year std warranty is given to address the issues if occur. All previous issues are addressed in old cars so they are trouble free too at the moment.

We cannot term RS2020 or Old 16/17 Turbo Civics programmed better or worst. Technically it is conservatively tuned as compared to old Turbos as per a known after market tuner's feed back. Especially low to mid range torque restricted and it feels a bit heavier than the old caliberation set up at touch / partial throttle push pull. Wide open throttle response is identical so the overall power and torque figures are same. But Good thing is this is not an issue as one can opt for custom tune if he wants to spice it up a bit.

Please correct your info. Since Oct 2017 Honda Atlas Recall for software cal upgrade to address knocking due to high concentrations of mmt in our fuel, all Stock Turbos running without any fault even on Regular Fuel no any issues reported / experienced so far afterwards. We as owners literally forgotton what knocking was.... hahahaha..... although its better to always remain it filled with HOBC if possible.
Definately Euro 5 fuel should be better than before and imo the Cat Converter and spatk plugs life will be increased / enhanced.
