EVO4S is the evolution of the well known EVO4.
It maintains the same connection logic, one connector per channel, but with a completely redesigned internal electronic board, fully compatible with the last generation of AiM dashloggers and with the new powerful Race Studio 3 software.

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.
And from analog/digital inputs, external expansions as well as predefined math channels. Sensors can be connected to 5 configurable analog channels, to the RPM input and to 2 wheel speed inputs.

AiM systems acquire data from the ECU of your vehicle.
The list of available ECU drivers, constantly updated and upgraded, is published here: it includes > 1,000 different ECUs, either Stock and Racing.
They are sorted by manufacturer/vehicle model: for each ECU you find the proprietary communication protocols, including the standard OBDII ones.
From a hardware point of view, AiM systems manage the following data lines:

• CAN
• RS232
• K-Line 

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 analog or digital inputs, ECU values, expansion values, GPS information or math channels.

MORE INFO

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

EVO4S is a modular logger, offering the opportunity to increase the number of channels, adding via CAN the following items:

Channel Expansion 

It permits to add 4 0-5Volt analog channels.

TC Hub
It adds 4 K thermocouples.

LCU-One Lambda Controller 

Wide band Lambda controller LCU-One, with Bosch LSU 4.9 probe, providing all Air/Fuel data, lambda value and exhaust gas temperature, allows to perfectly tune the carburetion.

SmartyCam HD cameras

The on-board cameras that overlays on videos the data sampled by your logger.
