Oil Metering Pump Setup Wizard
With Infinity Tuner connected to the ECU, go to the Infinity Tuner Wizard page called “Oil Metering
Pump”.
The OMP Sensor Setup affects the stepper feedback calibration. The default settings may require minor
adjustments. To determine if this needs adjustment, the OMP needs to be installed and Infinity Tuner
needs to be connected to the ECU. Assuming no ErrorMAP, you only need to use the table “OMP_Load
[%]” for calibration.
Step 1: fully populate OMP_Load [%] table with the value ‘0’. Record the value from channel
OMP_Feedback [V].
Step 2: fully populate OMP_Load [%] table with the value ‘100’. Record the value from channel
OMP_Feedback [V].
Step 3: set the wizard option “OMP Volts Min” to the minimum voltage recorded minus 0.05V.
Step 4: set the wizard option “OMP Volta Max” to the maximum voltage recorded plus 0.05V. Increasing
the voltage range by 0.05V on both ends will prevent an OMP_Error_Sensor while the sensor is at 0%
and 100% of its range. The OMP Cal Min can then be reduced to -1 or -2, while OMP Cal Max can be
increased to 101 or 102 to compensate for the expanded voltage range.
The OMP Load Axis setup lets you choose between kPa and psig for the main load axis.
The second failsafe described above is activated if there is a stepper motor position error or a sensor
error. The failsafe by default enables a Fuel and Spark Cut, as seen below. The Fuel and Spark cuts can
