The EVO4S acquires data from your ECU via CAN, RS232 or K-line and also from the internal accelerometers, gyro and GPS08 Module in the kit.
 
Aim EVO4s
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.
 
A wide range of sources for your data
The EVO4S car racing datalogger 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. 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.
 
Sensors
Many sensors can be connected to EVO4S via:
Internal three-axial accelerometer and gyro sensor
A built-in inertial platform lets you have the most powerful system for understanding oversteering, understeering, banking, etc.
 
CAN 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 integrated CAN output, you can now send messages directly to a CAN network to help you improve your vehicle control.
Endless Expansion Possibilities
The following expansion modules can be utilized:
Channel Expansion

You can add up to four 0.5V analogue channels.

LCU-One CAN
Wide band Lambda controller provides all the air/fuel data needed.

SmartyCam HD cameras
These amazing onboard cameras can overlay video feed over the sampled data.

Memory Module
The memory module comes in the form of a small SD car holder and it stores all the recorded data from the race.
