Installing a data acquisition system

Our customer asked us to install an AIM Evo4 Data Acquisition System (DAS) along with AIM's Mychron3 dash. The car is a first generation 997 GT3 that uses the CAN protocol to transfer information throughout the car's electronic system. We used a non-invasive method to tap into the CAN network to retrieve the data the system utilizes.

The design brief the customer provided was:

1. Install the EVO4 near the vehicle's centre of gravity
2. Dash should be removable in less than 30 seconds with no tell-tale signs it was there; dash should not block real dash
3. GPS antenna should be part of the interior and should not require placement when the DAS is used
4. DAS needs to be switchable so that data does not get overwritten unintentionally 
5. USB cable needs to somehow be accessible but also hidden

We installed the head unit near the factory ECU in the space normally used for other factory electronics. We fabricated a dash mount that uses the factory cup holder and ran the wires up through the centre tunnel to ensure a clean installation. Finally, we installed a switch in the centre console alongside the USB cable.

The feedback we received from the customer: "the install is clean, looks factory and exceeded my high expectations; a truly first-class install".

The system provides the customer with the following information to compare and learn from:

Vertical g's
Lateral g's
Longitudinal g's
RPM
Throttle Position Sensor
Individual wheels speeds
Engine coolant temp
Engine oil temp
Engine oil pressure
Steering angle
Steering speed
Brake switch
Gear selected
Fuel level in litres
Battery Voltage
GPS speed
GPS lateral g's
GPS longitudinal g's
GPS heading
GPS gyro

Merged with video using Trackvision software, the system in action:
