Gear Ratio Adjustment (2012+ Si)

Hi Hondata,

I wanted to see if it were possible to add the gear ratio adjustment onto calibrations for the 9th gen platform? Currently the only solution once an aftermarket gear set is installed, is to purchase an external dakota digital converter to have the Speedometer function properly and display the correct speeds.

Thanks,

Cristian

Please HONDATA will you support this? There's a lot of us with built transmissions and are having speedo and cruise control issues. I believe this would fix our problems for the 9th gen Civic platform.

All it should be is a copy paste from the 8th gen Civic calibrations to the 9th with the exception of the actual gear ratios. Looking forward on seeing this problem resolved. Thanks!

It is nowhere near a copy paste operation, which is why we have not done this. The 9th gen ECU is not the same as the 8th gen ECU. It does not store the ratios in the same way.
