The Memory handling in Ver 3.5 is changed to provide more GP outputs from the unused Coil and Injector drivers. The danger before was that when different Map files is downloaded into the Device, it may override critical setup values which could damage the device or components on the engine. […]
Air Temperature tuning
The Air temperature sensor is used to compensate with fuel and spark timing for density changes in warm or cold air. Neglecting to wire it in may result in the engine detonating when it is Hot. Not all engines have air temperature sensors mounted on them. Most sensors were incorporated […]
Water Temperature tuning
The water temperature sensor is used mainly for cold start compensation with fuel and spark timing graphs. There is however a couple of functions that requires compensation with temperature like idle control, accelerator pump, prime pulse etc. Neglecting to wire the sensor in may result in the engine not being […]
MAP Alt Swop
This function is for Orion to swop the external MAP sensor with the onboard Altitude sensor. This will enable the tuner use the On-board 3 bar sensor for a MAP sensor instead of an altitude sensor. It will also allow the altitude sensor to move to the external input. Note: […]
Altitude Compensation
The ECU can compensate for altitude differences in pressure. It will adjust the fuel mixture and the timing in relation to altitude. Orion has an optional On-board 3 Bar MAP sensor which can be used for altitude. This is optional and has to be ordered separately. With Map/Alt Swop the […]
Throttle Selection
This setting is developed to use a MAP signal on multiple throttle body engines. The problem with them is there is no intake plenum where the vacuum could be measured. The vacuum signal only makes a spike when the valve opens. This spike is also there only once in two […]
MAP Sensor
This sensor measures the MAP (Mean Absolute Pressure) in the intake plenum. This is the main sensor for the ECU to calculate the fuel amount which is injected into the engine at different conditions and load requirements. This sensor, however, does have its shortcomings when it comes to engines with […]
Fuel Configuration
Start enrichment This value will help an engine to stabilize after starting. This amount will be added to the injector time after the engine is started and reaches 500 RPM. It will then be phased out in a couple of revolutions. This value is also compensated with the water temperature […]
TPS Sensor
This sensor indicates to the ECU what the driver wants to do. It is also used for many features in the ECU, such as fueling, accelerator pump, idling control, fuel cutoff, cam control, automatic transmission control, etc. It is possible to control the engine without this sensor but with limited […]
Coil Driver Selection
This block selects the type of coil driver used by the ECU. It is note used in Orion as it has Pos and Negative drivers on the board. It will be blanked out. Note that the coils must get their power from the ECU power relay. At startup this relay […]
