Just accidentally bought a 2020 V3 AP for my 2021 WRX. I tired to install it and got a unknown ROM error, and that my car is not supported. I feel really stupid right now that I bought the wrong one. I want to return it to the website that I bought it from but they say if it was attempted to be installed then they can't return it. SO will I be able to return it? I thought it would work on the 2021 as they have the same ECU but I really don't know much about tuning, first time. Is their anyway to update the 2020 AP v3 to a 2021 because I've heard that you can. Thanks
