This Hondata Jailbreaker temporarily bypasses the CAN gateway on the 2020 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.
This Jailbreaker device (not the instant jailbreak) can be used on as many vehicles as you like. You still need to purchase the instant jailbreak for each different vehicle.
