It uses the crank wheel for timing, but I wouldnt just trust that is correct as all manufacturers have engineering tolerances.  The offset will be close to zero on most.  My Evo VII offset is -1.  
If you are missing a timing mark then paint your own mark on.  

From memory the sleds had a plug that you can connect an external power supply to and this will then liven up the ECU and the rest of the sled. 
 
At the ECU connector if you put 12V to pin 17 of the 34 pin connector and ground on to pin 15 or 16 the ECU should power up. 

Im not sure sorry, I have a lack of experience with this type of vehicle.  We dont even get snow where I live and Link stopped making those ECU's long before I started working here so I dont know much about them.  I believe all sales and tech support of the snowmobile ECU's was done by a company in Canada as they had most of the knowledge.  Simon has worked here longer than me so hopefully he knows more.  I assume there must be some way to power it up without the engine running - otherwise you would never be able to change a map or update firmware.  

Remove a tooth.

It is not highly critical which tooth you remove, but I would suggest removing a tooth that is under the crank sensor when the cam sensor is roughly half way between edges.

 

Yeah this is the problem.  Unfortunately both the rising and falling edge on trigger 2 are very close to the trigger 1 falling edge.  So I dont think swapping the trigger 2 edge is going to help much.
Is it possibly to maybe slot the holes a little on the cam "tooth wheel" to just rotate it a small amount, 5-10 degs?
Or as you suggest removing a tooth from the crank wheel would be another option.  

I would still suggest you pull a spark plug out to confirm, I have been caught before where a timing light won’t pick up a spark when cranking before if the timing is a long way off.  If the offset is out by a long way and it’s sparking on the intake stroke when there is vacuum in the cylinder for example, the spark voltage is very low and not enough to trigger the lamp.

I would actually use rising edge on trig 2 - sorry I attatched the wrong picture earlier.   
But I dont see any reason for no spark in that log.  There is RPM, dwell being commanded, and no ign cuts so you should have a spark.  Have you pulled a plug out to confirm? 

Can you please give us a log of it cranking using the multitooth mode and a copy of the map too please.

The trigger pattern is not a good match for the GM 24X, I think the problem maybe your trigger 2 is high for 23T and low for 25T.  It should be high for 24T and low for 24T.


 
I think multitooth mode should work though.  
Did you try settings like this?  

 

Will need the triggerscope to see what is wrong with the signal.  Teamviewer has a file transfer function or you can get the remote user to email the file to you.
