Software mismatch?

Post by SamYu2014 »

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. I know my stock Firestone tires are crappy but I will wait until they worn out to get better tires.

Yes, they must have updated the software. The KTuner Unit Info will show you the current software after you connect to the ECU, just in case they ever do this again. The A57 has many more features than the A55 does, so enjoy!
