In the realm of motorsport and racing, accurate data is invaluable. Whether you're a professional race car driver aiming to shave off a fraction of a second from your lap time or a weekend enthusiast looking for a bit of fun on the track, having a reliable way to measure performance is essential. Enter "Harry's LapTimer," a tool that has revolutionized the way many racers, both amateur and professional, track and improve their driving.

Overview

Harry's Lap Timer, often simply referred to as "HLT", is a versatile and robust smartphone application designed for motorsport enthusiasts. It combines the technology available in modern smartphones, such as GPS and accelerometers, with an easy-to-use interface to provide detailed data on a driver's performance. With this tool, users can measure lap times, analyze speed and acceleration, and even compare their performance against previous laps or other drivers.

Key features

  1. Precision timing: At its core, HLT provides accurate lap timings down to a fraction of a second, allowing users to monitor their progress in real-time.
  2. Data analysis: Beyond just timing, HLT offers extensive data logging. This includes metrics like speed, g-forces, and cornering angles. This data is crucial for drivers looking to understand where they can improve.
  3. Video overlay: One of the standout features of Harry's Lap Timer is the ability to overlay performance data on video recordings. This allows drivers to review their laps visually, seeing exactly where they gained or lost time.
  4. Track library: The app comes with a vast library of famous racetracks from around the world. So, whether you're driving at the Nürburgring in Germany or the Laguna Seca in California, HLT has got you covered.
  5. Customizability: For those who drive on lesser-known tracks or even want to create their custom tracks, HLT offers the capability to set up custom start/finish lines and sector times.
  6. Integration with external devices: The app can also integrate with various external sensors and devices, enhancing its data collection and accuracy. This is especially useful for serious racers who might have specialized equipment in their vehicles.

In the world of motorsport, where fractions of a second can make the difference between victory and defeat, Harry's Lap Timer has carved out a niche for itself as an indispensable tool. It blends the power of modern smartphone technology with a deep understanding of what racers need, delivering a product that is both highly functional and user-friendly. Whether you're trying to beat your personal best or analyzing your performance on a new track, HLT is a companion you'd want in the passenger seat.

Harry's LapTimer app versions

Harry's LapTimer (HLT) offers multiple versions of the app to cater to different users, ranging from beginners to professionals. The distinct versions are:

  • Harry's LapTimer Rookie: This version is designed for those who are new to track days and lap timing. It's the entry-level version with basic timing functions.
  • Harry's LapTimer Petrolhead: A more advanced version than the Rookie, the Petrolhead edition provides additional features such as video recording, multiple track day management, and advanced data analytics. It's ideal for serious enthusiasts who want more detailed insights into their track performance.
  • Harry's LapTimer Grand Prix: The Grand Prix edition is the top-tier version of the app. It offers all features available in the Petrolhead version but adds multi-cam recording, more sophisticated analysis tools, and supports additional sensors. This version is geared towards professional racers and those who want the most comprehensive set of tools to analyze and improve their driving.

In addition to these main versions, Harry's LapTimer also provides various add-ons and extensions that can be integrated for a more personalized and enhanced experience. Users can check the app store descriptions or the official website to get detailed feature lists and differences between these versions.

Remember to always check the official channels or app stores for the latest updates or new versions, as software apps, including Harry's LapTimer, frequently update and may introduce new features or versions over time.

OBDLink adapter is the OBD adapter you want to use

Harry's LapTimer (HLT) combined with an OBD (On-Board Diagnostics) tool like OBDLink can significantly enhance the data-driven insights drivers get about their vehicle's performance on the track. This combination allows users not only to measure lap times and analyze their driving but also to obtain real-time data directly from the vehicle's ECU (Engine Control Unit). Here's what this combination brings to the table:

  1. Deeper xata insights: With OBDLink feeding data to HLT, users can access and record specific parameters like engine RPM, throttle position, coolant temperature, fuel consumption, and more. This is in addition to the GPS-based insights that HLT provides by default.
  2. Video overlays with OBD data: One of the standout features of HLT is the ability to overlay data on recorded videos. When integrated with OBDLink, this overlay can include real-time engine and vehicle metrics, providing a holistic view of each lap. It’s beneficial for racers who want to see the direct relationship between their driving technique and the vehicle's response.
  3. Driving analysis: By understanding both the vehicle's performance (through OBDLink) and driving metrics (through HLT), drivers can get a comprehensive view of areas for improvement. For instance, correlating engine RPM or throttle position with cornering speeds can provide insights into shifting patterns and throttle control.
  4. Enhanced diagnostic capabilities: OBDLink, being a diagnostic tool, can also check for any trouble codes in the vehicle. Though not directly a feature of the lap timing function, it’s good to ensure the vehicle is in top condition before pushing it on the track.
  5. Wireless connectivity: Modern OBD tools like OBDLink MX+ often come with Bluetooth or Wi-Fi connectivity. This wireless connection allows for a seamless transfer of data to smartphones or tablets running the HLT app, making the entire setup quite user-friendly.
  6. Improved accuracy: While HLT uses the phone’s internal sensors for measurements, having data directly from the vehicle's sensors can enhance the accuracy of certain metrics.

It's essential, however, to ensure compatibility. Not all OBD tools may work perfectly with all apps or vehicles. Before purchasing or setting up, you should check whether the specific version of OBDLink you're considering is compatible with Harry's LapTimer and yourvehicle.

In summary, the combination of Harry's LapTimer and OBDLink transforms a regular track day into a data-rich experience, providing racers and enthusiasts with invaluable insights to enhance their driving skills and understand their vehicle's performance at a granular level.
