S65 seems even fire engine. 90deg V8. I believe same triggering pattern as V10. IIRC 6 even sectors on inlet cams, 8 minus one on exhaust, 60-2 on crank.
Best scenario would be if one V88 stands for VANOS control and one of DBW sides. Is it possible, or VANOS should be divided between two units? Then - can one ECU control just exhaust, another - just intake VANOS? And share same target map for both cams?
