### 3/5 — It’s ok, has bugs

*2026-03-29*

I downloaded this to play with final drive ratios given custom gear ratios, but it fails to update the analysis when I change the final drive ratio. It only works when I change transmissions from the drop-down, but now when I change the ratios in a custom transmission.
