Hi everyone! First time here! I have a 2015 Civic lxs (made in Brazil) with the 1.8 R18Z1 engine. The ECU code is R1E-P31. Is there any way to use hondata flash pro with it? If there isn’t I would very much appreciate guidance as to how I would be able to tune my ecu, I really want to squeeze some more power out of this engine! Thanks in advance 🙏🏽

I'm sorry, but that vehicle is not supported and is not something we plan to support.

Thanks for the answer! So would you recommend swapping the ecu for an American supported one? Would that work?

That is not something we recommend or support.

But would it technically work?
