Ordered Vems, forgot to write in "nissan" for engine specifications, so modifying order for Nissan Hall trigger. Guys said it could be solved by ignoring secondary trigger abouve 2500 under secondary trigger settings
I ordered the Ecu with 6high current outputs and 2 logic level outputs, so Im planning on using the 4 stepper drivers to control the other 4 ignition modules. They are all logic type moduleles.
I rewired the Ignition
Ec36 pin 11 logic level output with green wire goes to cylinder No.1
Ec36 pin 12 logic level output with orange wire goes to cylinder No.2
Ec18 pin 4 stepper output with purple wire goes to cylinder No.3
Ec18 pin 10 stepper output with red wire goes to cylinder No.4
Ec18 pin 5 stepper output with yellow wire goes to cylinder No.5
Ec18 pin 11 stepper output with green/black wire goes to cylinder No.6
Power to ignition coils goes to fusebox with two red/black wires, I will use each of them to power 3-3 coils with 12V and the stock Nissan coils need 30amp fused power
Vems warned me about checking the harness to make sure the Bosch LSU WBO2 connections are okay, and to make sure it's not wired to match the older and different pinout Bosch LSU 4.2.
The wiring was perfect as the following;
Ecu EC18connector pin6 with yellow wire is connected to LSU4.9 pin 2
Ecu EC18connector pin9 with red wire is connected to LSU4.9 pin 1
Ecu EC18connector pin13 with black wire is connected to LSU4.9 pin 6
Ecu EC18connector pin18 with white wire is connected to LSU4.9 pin 3
LSU4.9 pin 4 with grey wire is connected by the harness to fusebox with 5amp fuse
