Spent some time over the holidays and wrote a gearing app for Android... which I just finished adding to the Android Market.
The reason I am posting it here is because it comes with some features I have found handy since having my Tekin RS, along with being able to store your settings for it (so when someone asks you do not need to plug it in
I found often when changing up gearing, it messed up my RPM range that I had just perfected. By doing the math I found that if I calculated the speed based on RPM and FDR/Rollout and then reversing it with the new FDR/Rollout the boost seemed to work the same (and the motor temperatures too).
So this app shows the speed for your boost start and boost end (in km/h). After changing your Rollout/FDR you can adjust the RPM values to restore the speeds the boost affecting the car....
From my experience (carpet 80x36) the lower boost number is the apex speed on the slowest corner (and on our carpet track varies from about 12-20 km/h), and the max the speed at about 1/2 or 2/3 the straight (25 - 60km/h)
Big difference over gearing apps are:
* you to quickly skip throw spur/pinions using the volume buttons...
* you can calculate the pinion (using the set spur and tire diameter) from a given Rollout or FDR
* you can see the speed your boost start/end at before and after gearing changes which allowing you to correct the range (useful for Tekin RS and other boosted ESCs allowing RPM configuration)
* you can stop guessing which spur to switch to with the gear chart you can see which spur gives you the ratios with your pinions
* you can forget your settings because TwitchRC remembers them for you.
A future version will allow you to download setups to view/edit.
