Racerender gear8/1/2023 ![]() Just find the plug that goes directly in your rear brake light. ![]() This is the easiest of the two so lets get started on that. The Factory Service Manual for your car/motorcycle definitely helps also! You're going to need a multimeter and whatever tools you need to get to these parts, hopefully just screwdriver and ratchet set. However, I will try my best to describe it to you and point you in the right direction.īefore we get started you have to be able to find these two points on your car/motorcycle otherwise we cannot continue any further. *You must be knowledgeable with the electronic system of the car/motorcycle you are trying to data log! Unfortunately, I cannot help you in this area since it varies from car to car / motorcycle to motorcycle. 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. Lean angle: thanks to a sophisticated algorithm you can view your lean angle for any turn without install any extra sensor or accessory on the bike.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. Predictive time: from the third lap you can see the predicted time instead of usual rolling time. ![]() Ideal time: setting the split times you can check your ideal time calculated by adding all the best split times. ![]() Split time improvement led: thanks to the pre-set intermediates, a led will warn you if you are improving your lap time, both at finish line and intermediates The touch screen makes using Start simple and intuitive thanks to the icon menu.ģ split times: is able to manage and record up to three split times. Touch Screen: say goodbye to uncomfortable buttons, Start is equipped with a touch screen with “Gloves Sensitive” technology that allows use even with gloves. It is possible to connect both models to the Box Expander modules.ĥ0Hz GPS receiver: the only lap timer in the world with a revolutionary 50Hz GPS receiver detecting the position 50 times per second Start is able to calculate lap times and draw trajectories with extreme accuracy. Start Next memorizes GPS trajectories, speed, the direction, acceleration and lean angle thereby allowing riders to study and analyze their performance on the PC. Start Basic is the entry-level version, without data acquisition lap times are visualised directly on the display. Thanks to automatic detection and a global database, the circuit will be automatically detected by the chronometer without the need to press any key. The new Start devices use a touch screen display with “Glove Sensitive” technology, allowing the rider to use the device even while wearing gloves, whilst the icon menu make navigation easy and intuitive. Start Basic and Start Next are the only chronometers in the world that use a GPS receiver with a sampling rate of 50Hz guaranteeing accuracy of lap times to one hundredth of a second and precision visualization of GPS trajectories which no other chronometer commercially available on the market today is capable of offering. A new ultra-bright display, a new graphics for displaying the lap time and a Wi-Fi module for wireless data download. ![]()
