I'm not seeing any dwell, start by updating your firmware to the latest one.

[KennyJ]

will do that , thought it was a symptom of the issue

[Adamw]

Do a trigger scope too please.

[KennyJ]

so , upgraded the firmware , here is the map , logs and triggerscope

Your trigger 1 signal appears to be inverted, not sure how that would happen but @Adamw might know.

I agree with Vaughan's diagnosis, the crank sensor waveform is inverted.  The only explanation I could put to that is someone has messed around with the wiring at some stage.  There are no pinout or sensor variations in these models that I have come across yet. 

I have seen the pins mixed up in the firewall plug a couple of times before so possibly something like that.

Crank sensor wiring diagram attached if you wanted to trace out yourself, but I suspect just swapping the +/- wires in the crank sensor plug will sort it.
