Hi,
First, I want to say : Thank you ! Fanaled is really amazing for my Formula rim.
Then, I have some idea for you.
In reality, in Formula 1, revleds are used not only for the rpm but also to show the Kers, DRS or more. I've create a little video to show you this : here (sorry for the low quality...)
That can be an idea if you can add the DRS and the KERS in Fanaled.
Note : I'm sorry for my english. I'm french
