Just called Power Commander Co. themselves to get a straight answer and after being on hold for 15mins I was told that for the SP1 the Power Commander model # is: 105-410 and it is the same for the SP2! I asked, "what about the wiring harness and them being different?" he told me that the only difference would be the map installed on the Power Commander that would be specific to SP1 or SP2. Which the PC website has both as well as if you chose to Dyno it and create the best map possible.
In Summary the Power Commander for the SP1 and SP2 are the same exact units and wiring harness, all that is different is the map you load on it.
