The EVO4s Downhill Bike Racing Data Logger offers a light weight, full data logging facility for improving bike and rider performance. Optional suspension sensors available.       

Aim EVO4s Downhill Bike Racing Data Logger

Comes with Race Studio 3 software to fully analyse your riding and bike configuration performance.

Aim Evo4s Downhill Bike Racing Data Logger

The Aim EVO4s Data logger is the new powerful and flexible data logger, an evolution of the well known EVO4. It maintains the same one connector per channel connection logic, but with a completely redesigned internal electronic board. Aim EVO4s is fully compatible with the last generation of Aim dash/displays and with the new powerful Race Studio 3 software.

EVO4s Data Logger

A wide range of sources for your data

The EVO4S car racing data logger samples all the information you need: data coming from your bike sensors, from the internal accelerometers and gyro and from the GPS08 module included in the kit.

You also get data from analogue/digital inputs, external expansions as well as predefined math channels. Sensors can be connected to 5 configurable analogue channels, to the RPM input and to 2 wheel speed inputs.

GPS08 Module

GPS technology represents a true revolution in racing data acquisition. Now, thanks to GPS08 Module and Race Studio 3 software, as soon as you start your track session you can immediately sample lap and split times as well as speed, position and acceleration… all the information needed for engine tuning as well as for improving your driving technique.

GPS 08 GPS MOdule

GPS 08 is more precise than most of the existing GPS systems, as it has been designed to add to the GPS satellite’s signal the Global Navigation Satellite (Glonass) system’s signal. With an average of almost twenty satellites working in conjunction, GPS 08 guarantees a precision and a reliability simply not comparable to the old generation GPS systems

The GPS 08 Module included in the Aim EVO4s kit, provides the following information, updated ten times per second:

  • Position (latitude, longitude, altitude)
  • Speed
  • Longitudinal acceleration
  • Lateral acceleration

If EVO4s knows the finish line of the track and the split coordinates, it can calculate and show:

  • Lap Times
  • Split times

GPS08 is more precise


Many sensors can be connected to EVO4s including Linear Potentiometers and speed sensors. (See our full kit for more info)

Internal three-axial accelerometer and gyro sensor

A built-in inertial platform lets you have the most powerful system for understanding rider performance.

Internal three-axial accelerometer and gyro sensor

Digital Output

EVO4s features a 1 amp at 12 volts digital output. You can configure it in order to turn it on or off depending on the value of the analogue or digital inputs, ECU values, expansion values, GPS information or math channels.

CAN Output

With the CAN Output you can send messages directly to an existing CAN network in order to improve the range of vehicle control possibilities.

Download your EVO4s data to a pc for professional data analysis.

Data recorded by EVO4s can be downloaded to PC and analysed with the professional Race Studio Analysis software: graphs, histograms and tables will help you evaluate your performance, providing an objective support to avoid mistakes and improve your driving technique.

Key Features

  • EVO4S samples all the information you need: data coming from your vehicle ECU via CAN, RS232 or K-line, from the internal accelerometers and gyro, from the GPS08 module included in the kit.
  • Completely re-designed internal board
  • 5 analogue channels with configurable 12 bit 0-5 Volt, 0-500 mV, 0-50 mV inputs or thermocouple input, used to sample data coming from temperature, pressure, suspension and other kinds of sensors.
  • 2 speed inputs, which allow to monitor the different wheels behaviour.
  • 1 RPM input, which manages square wave signals transmitted by the ECU, or pulse signals picked from the coil command (low voltage).
