2025 Civic SI compatibility?

[selfdestrukt]

Hi I just recently picked up a flashpro from an authorized dealer and it said on the site that my car was compatible. I m having issues getting it to recognize the vehicle. So I'm wondering if it really is compatible or I'm doing something wrong. Thanks for your help

Sorry, the 2025 Si is not yet supported. We do expect to support this vehicle soon but do not have a time frame yet.

Hello, following up to see if there is an ETA for MY25 support. I got excited because I saw the 1/11 software update but that did not include Si. Thank you.

1-3 months would be my guess at the moment.

Trying to update head unit but receiving error code “TT02”.

Google claims:
The Honda Civic code TT02 indicates a communication error, often during Over-The-Air (OTA) infotainment system updates, pointing to issues with the vehicle's Telematics Control Unit (TCU) or CAN gateway, requiring a dealership visit for diagnosis and potential replacement or connection checks, though some users found it resolved itself or with specific WiFi/Google setup.

Could a possible cause be the CAN Bridge preventing update? If so, should I reflash to stock; remove CAN Bridge; update software; and reinstall CAN Bridge/Reflash after?

I do not think the CANBridge is the cause of the problems. If you wish you can unplug it; it is only used when reflashing.
