![]() You won't be able to tell from the data how hard you're pressing the brakes, only when you started to press it or when you let go. The downside to this is that the brake light only has a one bit resolution (ie. There's a big problem with the brake sensor though, most cars/motorcycles don't come with a pressure transducer sensor in the brake line, but we can tap into the brake light circuit. These are where the most improvements can be made to improve your laptime. ![]() The 3 main sensor inputs that I believe are the most important to look at for a beginner are 1: Throttle Position, 2: Brakes and 3: Position (GPS). So we'll go straight to the source and do it manually. But, my motorcycle doesn't have OBD and OBD is missing a key input which is the brakes. This can all be done nowadays with an OBD bluetooth module and a smartphone since it has GPS. There are many ways to do this, the most popular one is dumping data from the OBD port. There are some current limitations such as data resolution and data syncing from different inputs, but it's a good way to get your feet wet into data logging. Way back when, I originally I used a SmartPhone app with an external GPS unit for data acquisition but soon after upgraded to an AiM Solo 2 DL.This is an old project of mine that I got asked a couple of times during a trackday and figured I'd post it up for people interested. Since moving to the AiM equipment, several riding friends have done the same. Here I’ll share some of the things I do to automate and simplify data acquisition. Reflecting on what I’m going to mention comes largely influenced by my day job in IT where I try to automate whatever I can, make it reliable and almost appliance-like. ![]()
