Pretty much what Ben said.
The "classic" DIYAutoTune wiring of the ignition system puts "Spark A" on the 2/3 cylinders, and "Spark B" on the 1/4 cylinders. Depending on your point of view, that could be considered backwards. However, they also set up the decoding of the CAS "backwards", so it all evens out in the end.
I personally wired my ignition the "correct" way, as I'm running a 36-1 crankwheel with the missing tooth in the traditional location (just prior to TDC), therefore my firing order cannot be reversed in software to compensate for reversed wiring.
