I'm trying to set up camsync on BMW M50 inline-6 engine. The engine starts and revs smooth but it shows trigger errors and tends to foul plug on cyl6. I did some triggerlogs with Vems Tune today. Maybe someone can comment my triggerlogs.
Triggers:
Primary - 60-2, VR
Secondary - 1 tooth, Hall
FW 1.1.81
VT 2010-08-19
Config - http://www.vems.hu/files/Reinis%20Andersons/v3.3_n002875-2010.09.03-23.33.48.vemscfg
Triggerlog (.csv and .triggerlog)- http://www.vems.hu/files/Reinis%20Andersons/Camsyncm50.zip
Should I try to change secondary trigger polarity? Maybe advance secondary trigger tooth about 3 crankdegrees?

Screenshots from Trigger Analyze:
In this screenshot I changed secondary trigger edge from falling edge to rising edge. Loged it to show Hall polarity and how the secondary trigger tooth is positioned.
Thanks, Reinis.
