Air dash direction?

[SimicEngineer]

I got an upgrade to allow air dashing in "any direction", but it doesn't seem to work right. I can get some vertical movement on a dash, but the angle doesn't match the passages through the spikes in the following area. Is there some kind of trick to controlling the direction? What am I missing here?

edit: never mind, I was doing the Savage Divide instead of the air dash.
