LS1 swapped RX8 tuning question

[Medic1026]

I have an LS1 swapped into my RX8. The harness and ecu are from PSI Conversions and I'm curious as to what software to tune with. I was informed you guys were the guys to ask so that's why I joined. I'm from the import world and I'm well versed in tuning familiarity however this domestic step has me a bit confused. The ecu appears to be an OEM LS1 so I'm wondering if it will tune like an open source or if it needs to be chipped.

Since this is an HpTuners forum, most everyone on here uses the software "HpTuners" to tune with. Search around youtube for some HpTuners demos, you can find a lot of good videos.
