I have a Volvo B230 4 cyl 8 valve engine with simple trigger:

It takes "forever" to sync and sometimes fires up immediately, it never complains about trigger errors but one thing is clearly seen :

If I run firmware pre 1.2.x it will sync and start immediately.

I have tried this on a V8 with only 90 degrees between crank teeth, it was almost impossible to get it starting. Downgrade to 1.1.96 and it fires right up every time.

Here is a typical cranking sequence, and clear to see seven (7) crank rotations before it syncs - with no fuel, so it didn't start, only for triggerlog cranking.

Here are my basic settings, anything to be changed here?
