- FlashPro firmware updated to version 156
- [2017+ Civic Si] Fixed boost by gear
The problem is that along with the oil dilution ECU update Honda is updating the transmission software to 2017, and the ECU / TCM versions have to match, so 2016 Civics can either use a 2016 or 2017 binary and there is no way of determining which should be the correct one. So when you return to stock it will ask. If you have had the Honda oil dilution update, then choose 2017, otherwise choose 2016. Note that hatches and anything other than 2016 Civics are not affected.
