be individually enabled or disabled, and their RPM setpoints can also be adjusted. The wizard option
“OMP Error Position Max [%]” determines the allowable error between the requested position and actual
position of the stepper motor. The default is 5% error.
The OMP Stepper Setup default values are designed to work with the Mazda Oil Metering Pump. These
values should not be adjusted unless attempting to diagnose a stepper motor problem.
STAGED INJECTION
The Infinity ECU can be configured to use Staged Fuel Injection. For the Mazda Rotary application,
Secondary and 3rd Stage injectors can be configured. The setup for Secondary injectors includes a
Staged Split table, allowing fuel flow split between Primary and Secondary injectors. Setup for 3rd Stage
injectors includes additional parameters based on engine load and engine speed. The Secondary staged
injection should be thoroughly understood and configured prior to activating the Tertiary injectors.
Secondary Injection
In the Infinity Tuner Wizard, go to the Injector Setup tab.
Select the total number of injectors.
Select the Fuel type for Secondary Injectors. Note that this Fuel Type applies to both Secondary and 3rd
Stage injectors.
Double click on the "Type" column for each injector that you want to set as a Secondary, and use drop
down menu to set Type to 'Secondary'. Set the phasing for each injector. In this example, the phasing is
setup for a 2-rotor 2-stroke engine, with 2 Primary and 2 Secondary injectors. All of the injectors will be
tied to Lambda1 Feedback when 02 Feeback is enabled.
