Hello Engdahl,

Please start with the basics, connect and setup your Nissan trigger as follows:

* primary trigger goes to the x cyl number window HALL (in your case 4cyl = 4 window).

* secondary trigger goes to the 360 tooth.

* verify window sync size, this is done as follows:

** forcing the ecu in safe mode, easiest todo by changing the prohibit low byte from (xx which is last two number of firmware version) to some other number.

** make a triggerlog cranking the engine 8-10 seconds

** your triggerlog will have both primary and secondary pulses logged (sectrig only inside the primtooth window). As an example here is a picture of one i made during some testing:

** take notes of the window sizes, Nissan trigger will sync to the longest window; for example if you Nissan trigger windows are 8-2-2-2 than we need to sync to 8sectrig window -> sectrig ignore should be set to 5-6.

** make sure to put your prohibit low byte back to the previous value to revert the safe mode.

* after window length verifcation and correct configuration make another triggerlog to verify all is well

If you have any further questions are problem starting after that, please make a sharing report containing both triggerlogs (safe mode with prim and sectrig), triggerlog after longest window calibration and a short vemslog of the cranking sequence. I'll review and come back to you with my findings.

Best regards, Dave
