The Orion ECU has the ability to use two injectors per cylinder. The way these injectors are implemented vary for different applications. If you use one fuel and the primary and secondary injectors does not differ too much in size, then the Ratio method is preferred. If you want to […]
Anti Lag
The Anti-lag function will help to keep the boost pressure up when decelerating in corners on the race track. This function will use the launch control settings which will add fuel and retard the timing. The correct installation requires an EGR valve to bypass boost pressured air from the turbo […]
Launch Control
· The Launch Control feature will spin a turbo to higher RPM’s while the vehicle is stationary. This is done by adjusting the RPM limiter, enrich the fuel mixture and retard the ignition timing. This will create boost pressure so that when the driver launches, there will be no turbo […]
Error Messages
The Silicon Laboratories IDE Software display different messages when it cannot connect to the device or the Debug Adapter. Fast way to verify if the equipment is correct is to see if you can get connection to another device if you have one. Below is a description of the messages. […]
Altitude Compensation
The ECU can compensate for altitude differences in pressure. It will adjust the fuel mixture and the timing in relation to altitude. The Mercury2 can do Altitude compensation by wiring an external 1.1 Bar Map sensor onto it. Select Altitude and click on Compensate. The Altitude sensor is pre-calibrated. You […]
Operation
To program your Product, first connect the Programmer to the Product’s Com Port. Connect only the P1 12-Way connector and earth the Product. Switch the ignition on. Click on the button to connect. The download button will become active, click on it. Now use the Browse button to select the […]
Fuel Pressure
The Orion ECU has the ability to control fuel pressure by speed controlling the fuel pump with Pulse Width Modulation (PWM). This is achieved by pulsing the driver at 300 Hz with a required duty cycle and then measuring the actual fuel pressure with an electronic pressure sensor. The duty […]
Installation
After downloading the Firmware Programmer software run the file mcu_ide.exe to install the software program. Follow the onscreen instructions till you are asked for the following. Click on Custom and uncheck Examples and Utilities. You will not need these and they will only take up unnecessary disk space. No harm […]
Precautions
1. Do NOT program the incorrect product firmware in your product. This could lock the microprocessor for operations and destroy the hardware. Each products firmware starts with the product name to minimize mistakes. Most of the firmware do have hardware lockout protection but the Test Programs and the older products […]
Introduction
Each product has a selection of firmware programs. These programs are the heart of the microprocessor that initialize the product to operate in a specific way. Each engine has different sensors and electrical accessories and requires different programs. The firmware programmer allows the users to change the Firmware program in […]
