as title states im in a situation where i need an aftermarket computer for my K series.

and i need some good information and guidelines
about a EMS 4424 stinger V4,
im wondering if this would hook up into my EG K swap,
i have a stock prb ecu. but im looking to upgrade abit.
kpro atm is out of the question with the prices so high, and no need.
in need of a ecu that can cover all the basics, which any ecu can.
but someone has offered me a ems ecu, and im wondering if this would be plug and play or would i have to make a harness to get it connected?

if anyone wishes to ask what ecu to run on your car or need help, just post along and im sure someone can help out.
