If you stop and think about it, the "technical" firing order has to be 1342. Cylinders 1&4 have the same piston position, and cylinders 2&3 have the same piston position. Lets say cylinder 1 is at TDC and ready to fire. This means that cylinder 4 is at the top of the exhaust stroke, and ready for the downward intake stroke. Its not posible to fire #4 next, because you have an ignition event every 180 degrees of crank rotation. The next cylinder to be at the top of the compression stroke would have to be either the # 2 or #3 cylinder, depending on how the cams are working the valves anyway. So really it could be 1243, or 1342..Since its wasted spark, there are several ways to wire it, so it still runs ok of course. 1&4 wires have to be on the same coil pack, and 2&3 have to be on the same coilpack.
