Product Description
Combination G Meter + Chassis Angle Sensor for Holley Terminator, Dominator, and HP – ACAS+X
A combination of our wheelie management sensor (ACAS) and X-axis accelerometer from our 4thAXIS with corrected and raw X acceleration, for HOLLEY EFI ONLY.
Sends 4 channels of high-speed data to Holley ECU via CAN bus: Chassis Angle, Pitch Velocity, Raw X-Accel, and Corrected X-Accel

This is a combination accelerometer and wheelie-management sensor for Holley ECUs only. See our store for other supported ECUs.
This sensor communicates to the ECU via CAN Bus. It is ONLY COMPATIBLE WITH HOLLEY ECUS USING HOLLEY CANBUS 1MB PROTOCOLS.
ACAS+X sends 4 high speed CAN data channels to Holley: Chassis Angle, Pitch Velocity, 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 real-time 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 range is +/- 4G.
The system is zeroed each time it’s powered on OR can be configured to “zero” whenever a message is received from the Holley ECU: for example, zero the ACAS-X whenever you press the trans brake button. This uses all the normal onboard logic and I/O configuration on the Holley: no configuration of the ACAS-X is required.
