Carefull !!! SCT had some screwed up updates last week ! Dont know if they fixed them yet .
Do you have Just the handheld ( Xcal-II ) unit ? Or the Pro Racer Package ?
If you have the Advantage software disc & Dongle & you will need to call SCT next week go get it activated .
If you got a dealer flashed handheld From a dealer , you just hook up to OBD port & follow instructions . Pick one of your three pre-programmed flashes to replace stock flash with .DO NOT ABORT FLASH once you have started an actual re-flash . to do so will lock up your ECU .
If you bought it used & it is "married" to another SRT4 ECU , you will also have to get in touch with SCT to get it unlocked or "divorced" from previous ECU so you can lock it to yours .
Welcome to the world of ECU reflashing , SCT style .

There is a lot of info in this section & the wiki if you are a PRP user , but there are some holes in it , so if you cant find what your looking for ask . Im in my first year with the PRP & there is a big learning curve , so I know how intimidating this stuff can look .
If you are going to stick with a dealer flash setup , choose your dealer wisely . The flashes are only as good as the programmer . Some have a much better understanding of this system than others . But all the shops will tell you they are the best .
