I got cyl1. You know that coil 4 fires at tdc (give or take) of cyl 4. Therefore when cyl 4 is firing, assume 1,3,4,2 and you get

cyl 2 compression
cyl 1 intake
cyl 3 exhaust.

Therefore the exhaust event we see when coil 4 fires, is number 3 on exhaust stroke. The drop out occurs one cylinder before the coil event, making it cyl 1.

Will have to buy a WPS one of these days
