"At the moment the data logging is ever-present and we record everything all race weekend. Most of the time we don't need it every session but when we do, it is there. If a rider says he is having a problem on one section or corner of the track then I can go exactly to that point at look at exactly what is happening, like RPM, throttle position, gear position and see how the rider is using the bike. We can then make some changes to the ECU to try and help. The ECU controls a lot of different things to do with the rideability of the engine and virtually all bikes have some sort of rideability control. At the beginning of the season we try to get a setting for the rider that will be effective across most the tracks and the bike has a few different sensors that normally adjust the engine for the weather conditions. The only thing the sensors cannot account for is the state of the track.
