Combination G Meter + Chassis Angle Sensor for Megasquirt 3 – ACAS+X

This is a combination accelerometer and wheelie-management sensor for Megasquirt-3 only.  (any megasquirt-3 based ECU such as MS3 Gold, MS3x / Kit, MS3-based PNP units, etc.)

This sensor communicates to the ECU via CAN Bus.  It is ONLY COMPATIBLE WITH MEGASQUIRT-3 ECUS USING MEGASQUIRT CANBUS.

ACAS+X sends 4 high speed CAN data channels to your MS3:  Chassis Angle, Pitch Velocity, Raw X Acceleration and Corrected X Acceleration.

Chassis Angle is the Pitch or wheelie angle of the chassis, Pitch Velocity is the rate of change of Chassis Angle.  Pitch Velocity has shown to be more useful than Chassis Angle alone for power management.  Observing realtime velocity of your chassis is far more useful than the chassis angle itself.

Raw X-Accel is the normal X-Axis accelerometer (G-meter) data, uncorrected for chassis angles.  Corrected X-Accel is a corrected acceleration figure that produces more consistent data car to car and pass to pass than raw, uncorrected data.  Accelerometer measures a range of +/- 4G.

The system is zero’d each time it’s powered on, OR can be configured to “zero” whenever a message is received from the MS3 ECU:  for example, zero the ACAS-X whenever Launch input goes active (when you press the trans brake button).   This uses all standard onboard logic and I/O configuration on the Megasquirt-3 ECU:  no configuration of the ACAS-X is required.

• Mounted in a watertight case, using a high quality Deutsch DTM 4-way connector
• Comes with a 4-ft flying lead harness with the mating Deutsch connector already installed.
• ACAS-X wiring requires only four simple connections.
• All software configuration is handled inside the Megasquirt-3 ECU.
• ACAS units may take up to 7 days to ship.
• Each unit is hand assembled in the USA, tested and calibrated individually.
