PI 2-Axis G-meter: complete with necessary wiring and hardware. Compatable with 


Link to G-Meter (Accelerometer) Instructions


Our 0-5v Analog Sensors are compatible with most major ECU manufactures such as Holley™, Fuel Tech™, Haltech™, MoTec™, MaxxECU™, and many others!



Holley ECU Sensor Supply Voltage ("5V") varies from ECU to ECU. Actual measurements taken by Plimpton Innovations, LLC (using calibrated measuring equipment) have varied between "4.73V" to "4.89V".  This does NOT impact sensor performance, however, calibrations may require slight modification. On average:

  • "PIN LOW" values: subtract "0.02V" from values on card. 
  • "PIN HIGH" Values: subtract "0.09V" from values on card. 

Holley User Example

"PIN 3 LOW" value on card = 1.24 V, Holley users should use 1.24V - 0.02V = 1.22 V.

"PIN 3 HIGH" value on card = 3.74 V, Holley users should use 3.74V - 0.09V = 3.65 V.

So the voltage values along the bottom row of the calibration table should read from 1.22V to 3.65V.
