These drawings explain how the injectors are connected for each injector driver. The amount of connections will vary with engine size. (See specific drawings for your application.) Batch & Split Batch Wiring With this method you always combine 2 injectors in Parallel. In this drawing A1 is on cylinder 1 […]
Optic CAS Cam Angle Sensor
This chapter discuss the connection and settings for the Optical CAS. For fault finding and testing see the Testing Magnetic Crank sensor chapter in this manual. First ensure that the setup in Hyperspace is done according to the startup procedure. This means you will only have a P1 and P4 […]
Crank Angle 12T + 2Home
The 12+2home configuration has the same signal pattern as the old 24+TDC configuration from the Toyota. Here there is no CAS but only sensors on the crank and cam directly. The 12 tooth gear gives a pulse every 30 degrees of crank rotation. There are 2 separate Home sensors. Usually […]
Cam Angle 24T + Home
The popular 24+TDC configuration from the Toyota, Mazda Rotary, Honda etc. engines can be used in many different ways. The 24 tooth gear gives a pulse every 30 degrees of crank rotation. Some distributor encoders use a combination of TDC and Home triggers with this gear. Below are explanations of […]
Sensor Tap-in
The Mercury2 controllers can be tied into existing OEM sensor circuits. There are a few rules around this to ensure that both systems operate correctly and is not damaged. It varies for the different products and sensors. Controllers that share a sensor, has to share a common earth connection. Differences […]
Testing Hall Crank Triggers
Work through each point below to find your problem. First ensure that the setup in Hyperspace is done according to the startup procedure. This means you will only have a P1 and P4connector on the Mercury2. The other connectors must be open, except for the Comms cable. Open the software […]

Dual Map Switch
The Dual MAP selection switch is a normal on/off switch that is connected to the ECU. When it is on it will connect the input to earth, this indicates to the ECU which map is required. Note: The ECU only tests this switch at startup and not on the fly. […]
Launch Control
The launch control input is an analogue input that combines a digital switch with a resistor to make a dual function input. It is used for Launch, Anti-Lag and Retard functions. There are different ways to activate launch but most methods use the switch on the dashboard. Same cases a […]
Fuel Pressure Sensor
The fuel pressure sensor relays the fuel pressure back to the ECU to control the fuel pump with PWM and keep a constant pressure over the injectors. This is important for the ECU to supply an accurate amount of fuel per engine stroke. The ECU can vary the speed of […]
