Hey guys. I just bought an SCT Xcal II off of a member of these boards (Thanks SVTTECH!), and I know nothing about it. As far as I know, he ordered it for his 01 GT with an O/R X, 4.10s, and a few other bolt ons. I have an 04 with nothing more than a CAI. I know I can't load his specific tunes to my car, but is it possible to go in and change it back to a stock performance tune? I called a local dyno shop, and he's willing to flash a "generic 93 octane stock performance" tune on it for 80.00. The previous owner also told me something about PCM codes, but everywhere I look, it seems that all XcalIIs are compatible with all 96+ GTs. Basically, can I use this thing right now or do I have to pay somebody for a tune?
Thanks dudes!

If it is set up for optional parameters, you can change the fuel trims, timing, shift points, etc yourself. Plug it into your car and see if it says "Optional Parameters?" If it does, you can change your tune. But be careful with what you do, you don't want to lean the engine out or add too much timing.
 
My PCM code is RKN2. I don't know what his is. I have it plugged into my computer, and I can see the only tune in it is 2001 Mustang GT 91+ tune. But that's his custom one with all the mods. On top of it, my freaking Vista computer won't recognize the SCT unit. When my girl gets home, I'm going to load it onto her XP laptop, and see if I can use the free Xtreme tune to change the paramaters and get it to work with my car. I think the biggest thing might be the PCM code. If I can't adapt for that, I'm stuck paying a shop.

I'm sure SVT unlocked the programmer so you can use it with your car. You can change the gears etc with the Xtreme tune software.
 
Yeah, I accidentally erased his tune, and for some reason the Xtremetune software won't let me create a new file. When I go to "file" it only says exit, not "new." I think part of my problem is the whole Vista thing.

I got it in the downloads section at SCT's website. Look under "other products" or "older products" and you'll find it.
