so i got curious as to how i would go about downloading new tunes on my sct scf3/x3 tuner for when i get my new parts soon. so i found out i needed to install an update off of the sct website first. so i downloaded the update but i'm having trouble installing it now. it's an ".lwu" file and when i click to install it all i get is a pop up saying that my computer does not know what to open it with. any1 know how to solve this issue?

Itīs a proprietary format, and itīs extension is not registered in windows. You have to open it through the update program itself(SCT Device Updater).

Iīd just get the updated interface program here by entering in the deviceīs serial #. Then use the live update feature of the program itself to update the SCTīs firmware. It should be called SCTDeviceUpdater.exe I think. Just be prepared to watch a movie or something, the thingīs flash interface is slower than hell. Took about an hour and a half to flash mine the last time.

This is a good thread. I'm subscribing & bookmarking so I can refer to this when I need to update my tuner too.

Windows Vista & 7 seem to Not like the SCT software for some reason.

Just gotta Ļrun as administratorĻ. Just right-click on the shortcut instead of the normal left-click, should be in the menu that shows up. Donīt think you need to use compatibility mode.
