AIM Mychron 3 dash questions

I recently purchased a Mychron 3 dash and I'm just a bit confused as to what I need to use it. I know I could get data acquisition but I don't really want to drop that kind of coin when other parts of the car need attention.



I'm wondering if I can get by with just a data hub or if I need a data logger? I basically just need it for rpm, oil temp, oil pressure and maybe head temperature for my FV.



Any advice appreciated.

thanks,

Brian
