This block indicates the type of coil combinations that can be used with this firmware. Some firmware programs will allow the user to select between the different coil combinations on his engine. Note: If you have an intermediate or lower hardware class ECU, you may only use single coil with […]
Crank and Cam Angle Sensors
These inputs are required by the ECU to determine exact crank and cams angles so that spark and injection timing can be calculated. VVTI cams can be positioned by the ECU. Their cam signals will be compared to the crank signal to determine the right position for loop control. Version […]
Mercury2 Test Program In an Out Ver 4.0
This firmware will allow dealers to test Mercury2 and see if all inputs and outputs are functional. It is for use on a Spitronics Simulater2 or 3. It is required before you accept Test 2 on the Portal. Note that this test is not 100% fool proof as the simulator […]
General Purpose Outputs
Output selection Version 3.5 can handle up to 10 General Purpose (GP) outputs to configure for several different functions. These outputs can be configured to use any of the analogue signals to switch relays on or off when certain limits are reached. Due to the number of GP outputs this […]
MAP Information
The Map information screen, Name Model and Engine, contains info for the ECU application for a specific vehicle. This helps the tuner to recognize previous work and tuning data. It is saved in the ECU and also in PC maps. It does not affect any tuning on the engine. Map […]
USB Communication Cable
Communication between devices and the Galaxy Software is done via a USB Cable manufactured by Spitronics. The reason for this is to reduce production cost and board space. These components are only used during tuning and you do not need the cable once the ECU/TCU are tuned. The electronics in […]
MAP Sensors
The Map Sensor is designed to measure the manifold’s intake pressure and use that signal as a fuel mixture control parameter. This sensor is enclosed in a plastic holder to protect it in the engine compartment. They come in 2 versions, 1.1 Bar in a red enclosure and 2.5 Bar […]
Stepper Idle Control
The Mercury Idle Control is designed to control small stepper idle motors. There are 2 types namely Type 1 for 4 coil common steppers mostly found with Toyota engines and Type 2 for Bi-Polar steppers mostly found on GM engines. This unit is micro based and receive an open or […]
Mercury Relay Overview
The Mercury Electronic Relay is designed to eliminate mechanical parts and contacts found in relays. It is more durable and has current limit protection of 45 Amp. This relay will be switched on or off by the Mercury2 on the ELR output. It will power the coils, injectors, fuel pump […]
Status Bar Display
This block at the bottom of the software displays all kinds of status, information and fault codes. Below is a description on types of messages. When no device is connected, the connection button may be open and an indication that no device is recognized. If you use a different USB […]
