Hmmm, I'm pretty sure what you're seeing is the empeg waking up to check and see if there's anything it's supposed to do... Now, the empeg software has never had a feature that needed to take advantage of this, so there never is anything it's supposed to do, and it goes back to sleep. Are you sure it does it every ten minutes, or ten minutes after you shut the car off?

There's also a posibility that you've got hijack's blinken LED setting set to only blink once every ten minutes while it's in standby, but you'd probably know if you'd done that.
