MAP Prediction / Fuel Film Model
How to set up the MAP prediction based transient throttle For this to work correctly, you need a functioning TPS (either cable or electronic) and MAP sensor (internal or external) Check that your TPS is operating correctly - ie, it moves smoothly ...
Zero Demand
This table is only active when the Throttle Position for a cable throttle or the Accelerator Pedal Position for a DBW throttle is below the Throttle Limits – User Demand Minimum value. Up to 2D mapping is available with this table. When VE or Mass ...
Fuel Cranking
The cranking fuel table is used to deliver a volume of fuel after the prime pulse but while the engine is below the Max Cranking RPM. This aids in providing the engine with additional fuel that may be required to star the engine after the prime ...
Fuel Prime Pulse
This table controls the volume of fuel injected into the engine when the ECU detects the engine has initially begun cranking and achieves synchronisation. It should deliver an amount of fuel as required to fire and start the engine whereby the ECU ...
Base - Stage 2
The Base - Stage 2 table exists only when the fuel Tuning Method is set to Injection Time and it serves as the raw injection time as delivered through the stage 2 injection system.
Base Fuel Tuning
The Base fuel table serves as the ECU's primary source for fuel delivery calculation. This table works in different ways depending on the Tuning Method set in the Fuel Tuning node. When Tuning Method is 'Volumetric Efficiency' this table is the VE of ...
Target Lambda
The Target Lambda table serves as a major part of the fuel delivery calculation in your Nexus ECU. It maps out the resultant mixture you want the engine to run at under various load and RPM points and is used in both open loop and closed loop ...
Fuel Tuning
The Fuel Tuning node configures the main Fuel System information for the engine. Fuel Tuning Method Sets the method for fueling calculation. Most installations will use Volumetric Efficiency. See also Fuel Base. Auto V.E Air Temp Compensation When ...
