Hi my gear box has these ratio (S9B EDM CIVIC) 1st=3,230 2nd=1.900 3rd=1.360 4th=1.034 5th=0.848 final=4.266 How to set them in the custom ration the number are different and there are no 5th Thanks regards

There´s probably a more scientific way to do this... but when I encounter a non-standard gearbox, I just tweak the numbers until the logger consistently shows the correct gear. There´s no setting for 5th gear, I assume this is because the Honda code just sees any ratio higher than 4th gear would be 5th. So when you set the 4th gear ratio correctly, 5th will work too.

i'll post an excel sheet later today

Please see attached. Fill in your gear ratios and you will get the values... If i have time or nothing to do i'll add them to eCtune..

Thank you Calvin Officialy this is stock Honda gear box with LSD, coming with EDM Civic MB6, the engine is a B18C4 same as B18C1 with IAB, exaust collector is the same as EDM ITR regards
