The Nissan 360 Opto Trigger Mode is designed for use with Nissan optical Crank Angle Sensors (CAS) that have 360 evenly spaced slots and 4,6 or 8 different width slots. Digital trigger decoding uses all of the 360 slots to achieve precise engine position calculation.

Of the 4, 6 or 8 slots, one will be wider than the others. The sizes of the slots are calculated by the ECU using the number of cylinders. This mode works with the coil on plug motors, a different mode (Nissan 360 Opto with Distributor) is provided for the motors that came factory with a distributor.

The Nissan 360 Opto with Distributor Trigger Mode is designed for use with Nissan optical Crank Angle Sensors (CAS) that have 360 evenly spaced slots and 4,6 or 8 different width slots. Digital trigger decoding uses all of the 360 slots to achieve precise engine position calculation.

Of the 4, 6 or 8 slots, one will be wider than the others and the rest will be the same size. The sizes of the slots are calculated by the ECU using the number of cylinders. This mode works with motors that came with a distributor such as motors such as the RB20E or RB30ET.

This mode works in a similar manner to the G4+ 360 Opto mode in that it looks for the widest slot rather than looking at the width of each slot, this means that this mode can be used with trigger wheels that don't follow the typical pattern of slot sizes based on the number of cylinders and the ignition system that the motor has. We recommend only using this mode if neither of the other Nissan 360 Opto modes work or are suitable for your application.

The Nissan 360 Opto Widest Slot Trigger Mode is designed for use with Nissan optical Crank Angle Sensors (CAS) that have 360 evenly spaced slots and 4,6 or 8 different width slots. Digital trigger decoding uses all of the 360 slots to achieve precise engine position calculation.

Of the 4, 6 or 8 slots, one will be wider than the others. This Widest Slot is used by the ECU to determine the engines position in the firing order. As the width of this slot varies depending on the exact CAS used, an automated setup procedure has been provided.

Setup Procedure:

Setup ECCS Trigger Decoding as follows (Read the entire process and ensure you understand before starting):

1.Ensure the 360 slot signal is wired to the ECUs Trig 1 input.

2.Ensure the 4,6 or 8 slot signal is wired to the ECUs Trig 2 input.

3.Switch the key on, do not start the engine.

4.Connect to the ECU using PCLink.

5.Ensure all Configuration options are correct.

6.Under the Fuel heading, select Fuel Setup. Set Injection Mode to OFF. This will prevent the engine from starting.

7.Under the Triggers heading, select Trigger Setup.

8.Select Nissan 360 Opto Widest Slot as the Trigger Mode. Note that this will initialise all trigger inputs to default values. The default values are as follows:

Trigger 1:

·Trigger 1 Type = Optical/Hall

·Trigger 1 Pull-up = ON

·Trigger 1 Edge = Rising

Trigger 2:

·Trigger 2 Type = Optical/Hall

·Trigger 2 Pull-up = ON

·Trigger 2 Edge = All

9.Crank the engine and capture a Trigger Scope.

10.Count the number of trigger 1 teeth that occur during the widest trigger 2 gap and enter it into the ECCS Widest Slot setting, typically this is a multiple of 4.

11.Crank again while watching Trig1 signal, Trig2 Signal and Engine Speed (can all be found under the Trigggers/Limits Tab in the Runtime Values Window). If both Trigger Signals and change to Yes and the Engine speed shows a consistent and reasonable value then the setting is most likely correct. If not, repeat steps 9 and 10.

12.Set Injection Mode back to the desired option.

13.If all is OK, perform a store to permanently save all settings to the ECU.

14.Set the base timing before attempting to start the engine (DO NOT JUST TRY STARTING THE ENGINE!).
