3 Axis Accelerometer: 4thAXIS channels 1-3 output a highly accurate X, Y and Z axis measurement of acceleration (G forces) to +/- 4G. This is transmitted to 3 separate channels in your Holley ECU over CAN Bus where you can log the channels and use them for any other logic functions in realtime, such as power management. -
Page 5: General Information And Use
General Information and Use: Power Consumption: The 4thAXIS uses 5 volt power and (sensor) ground directly from your Holley ECU, just like any other 5v sensors. This unit consumes no more than 0.003 amps (30 milliamps) during use. Performance: The 4thAXIS samples chassis orientation and movement at 400khz, and generates CAN data packets at 100 samples per second, the fastest a Holley can receive and store CAN data. -

(rear axle) as low as possible. The 4thAXIS will self-level each time power is applied, but the closer you have it mounted level in your chassis, the better. The mount can be rigid – unlike other inertia measurement systems, this one will filter high frequency noise from chassis vibrations. -

Page 15: Linear Acceleration Channel Configuration
Navigate to your I/O Inputs menu, find the Linear X Accel input and click “Configure” Set up your Corrected X-Accel sensor settings as follows: Custom 5v, Units = G, Format = 1.23, Sensor min = -4.00G sensor max = 4.00G 4thAXIS Instructions v1.2 pg. 15... - Page 16 (bottom) row 1.00v to 5.00v. Make sure you use 1.00 to 5.00v and -4.00 to 4.00G. Click on “CAN Settings” and configure the Corrected X-Accel CAN options as follows: YOU WILL USE THE CAN SERIAL NUMBER PRINTED ON THE BOTTOM OF YOUR 4thAXIS This completes setup of the Corrected X-Accel Channel.
