I've recently tested trying to tune my accord sport 2021 1.5 however it keeps showing up on a ktuner that my ECU is not yet supported was wondering if anyone with a 2021 1.5 accord is running into ECU issue with ktuners or has had the same problem

Does your ECU number fall into the ECU numbers that are supported? If anything like FlashPro, it supports certain ECUs and its very possible that Honda has a new ECU model split between 2021s that has not yet been added to the list of supported ECUs.

I got '21 Sport CVT 1.5T tuned with KTuner stage 2 and currently on Phearable stage 3. If your ECU is not on the list on this page 18+ Accord 1.5T – KTuner LLC and you really wanted to tune it, email their support. They will give you instructions on how to read the ECU so they can add support immediately. You'll need Ktuner dongle/unit for that though.
