This is the biggest the site tool will allow me to post. Thanks also to SimonR300, I can see some fun ahead tweaking this! The DRE has 6 led's which light up in pairs, left to right, from the 'get ready', 'get set', and 'change up now' stages. What I'm looking for when I'm sprinting, is to know that I'm in the right gear, using the best of the power available, rather than changing up too early, but protecting the engine by not overrevving it. I never look at the Rev counter (it's the original xflow version, so useless with this engine), and just listen to the engine, but there are many times, midway around a sprint course, when corners and gradients are coming at you pretty quickly, when I doubt whether I'm in the correct gear.
