    2021 challenger

    I posed this question to support by email, but their response may have disappeared in my deleted spam folder. Does the 2021 challenger require the ecm unlocking service? One page says 2020-2024 requires it, but another page says 2023-2024 requires it.

    As far as I know all Polaris MG1 require an unlock.
