You can still identify as pansexual if you're aspec, and particularly if you're acespec (after all, you're still attracted to people in some capacity, I assume, since you said aceSPEC and not ace? Although even if you were just aroace, with no -spec, you could still ID as pan, since attraction doesn't always fit perfectly into a single, or even multiple, boxes). If you don't want to or you don't feel like that fits you, though, I'd recommend checking out the labels panalterous and panplatonic!
