Karting's Favourite GPS Lap Timer 

The Aim MyChron 5 2T is our best-selling GPS lap timer with two sensor connections, specifically crafted for karting. Combining 30 years of experience with advanced technology, the MyChron 5 2T offers precise lap timing and advanced data analysis for both amateur and professional racers.

Why Choose the MyChron 5 2T GPS Lap Timer  

The MyChron 5 2T GPS lap timer revolutionises how drivers and teams monitor and analyse performance on track.

Due to its highly accurate 25Hz GPS tracking, large screen displaying lap times and comprehensive data logging capabilities, the MyChron 5 2T provides detailed performance analysis from split times and predictive times, racing lines, cornering speeds and braking points.

Advanced Display 

The MyChron 5 2T features a wide graphical display, ensuring excellent readability. Brightness and contrast are automatically adjusted to maintain ideal visibility in all lighting conditions, and this allows drivers to clearly monitor their best vs current sector times.

LED & Alarms System 

5 RGB shift lights can be customised to display lap times or function as traditional shift indicators. The 2 RGB alarm LEDs provide real time engine monitoring of vehicle temperature, ensuring the kart operates within optimal parameters and preventing overheating or potential damage.

Available Sensors 

With the MyChron 5 2T, you can select two temperature sensors to monitor your engine more precisely. Choose from:

  • Cylinder Head Temperature (CHT) Sensor: This under plug sensor measures combustion heat, helping detect overheating from lean mixtures or aggressive tuning.
  • Exhaust Gas Temperature (EGT) Sensors: M5 and T12 sensors monitor exhaust temps to fine-tune fuel mixture and optimise performance.
  • Water Temperature Sensors: Available in M10 (for Rotax, X30, OK) and M5 gearbox versions, these sensors track coolant temps to prevent overheating, with the M5 also being useful for monitoring gearbox water cooling in shifter karts.

Choosing the right pair depends on your engine type and what areas you want to monitor most closely.

Using 2 temperature sensors together gives a deeper view of engine performance and reliability. A popular combo is an EGT and CHT, ideal for air-cooled engines, providing insight into fuel mixture and combustion heat. EGT and water temp sensors suit water-cooled engines like Rotax or X30, balancing tuning with cooling system monitoring.

For shifter karts, pairing gearbox water temp (M5) with either EGT or CHT helps monitor both engine and gearbox temps, preventing wear. Some setups also run dual water temp sensors (M10 + M5) to track both engine and gearbox cooling separately.

The right pairing depends on your engine type and what you need to monitor; performance, cooling, or both.

Expand Your System

The ACC3 adds 4 channels and a CAN bus for integration with the LCU-One S Lambda Controller, SmartyCam 3, or Tyre Temperature Kit, and runs on external power. LCU-One S provides adaptable fuel monitoring, and SmartyCam 3 Sport records synchronised video and telemetry for analysis in Race Studio 3.

Please Note: You will need the MyChron ACC3 split harness to connect the MyChron to the ACC3.
