This Jailbreaker temporarily bypasses the CAN gateway on the 2020-2021 US market Honda Civic Type R so that you can instant jailbreak the ECU.
You do not need this product for the 2017-2019 US Honda Civic Type R or any other vehicle.
You still need to purchase the instant jailbreak.
The Jailbreaker device (not the instant jailbreak) can be used on as many vehicles are you like.
