Ignition firing
The VR6 engine is an even-fire engine with 120 degrees between cylinder events. It uses the same firing order as any in-line 6 cylinder engine, 1-5-3-6-2-4.
The ref tooth table is as suggested 0,40,20,0,40,20 (top to bottom).
Trigger settings
Use the "BMW M20" defaults in the primary trigger dialog to get the correct settings. This engine behaves just like any inline 6 cyl.
Still, use a timing light to verify ignition timing before powering the fuel injectors. Do it again once the engine runs to get a 100% correct value for "TDC after the trigger", use Tools -> Ignition lock and rev the engine a bit.

- The centerline of the cylinders are also offset from the centerline of the crankshaft by 12.5 millimetres (0.49 in). To accommodate the offset cylinder placement and narrow "Vee" design, the connecting rod bearing journals are offset 22° to each other. This also allows the use of a 120° firing interval between cylinders. The firing order is: 1, 5, 3, 6, 2, 4.
