Hi, all,

I have a 2016 Civic 1.5T CVT and my software number is A55. Yesterday I tried to flash. However if I use A55 tuner my check engine light is on. The error code is U0301, maybe it means software mismatch? The car drives fine.

So this morning I flashed A57 (the other option) and the check engine light was gone. My car was sent to fix before because of transmission control module failure (can not start). Maybe at that time dealership ungraded from A55 to A57?

It's no big deal and now everything works fine. I really like the Stage 0 tune, not too much torque to wheel spin and I can keep adding E87 gas. My stock Firestone tires are crappy but I will wait until they worn out to get better tires.

Return to factory will put you on the same software you're currently on.
Thank you! I saw my software is A55 from Ktuner, but if I flashed A55 it gives error code. A57 runs perfectly fine lol

If you return to factory in KTuner while on A57 software and the flash is successful you will be on factory A57 software. If you have to recover it will end up on whatever your very original software was.
