Re: Blue and Me Ecodrive Working in Linea !!!! Whooop dee do Sure ashwin. I have a index of 77 and am trying to push it to 80. I am quite sure that just for the sake of achieving index of 80, I will be able to do it, but it will not drastically alter my driving style. With my driving style, I am already at 77 and to push further, the changes required in driving style are huge.
