Not sure where to start

[94 Burban]

Hello everybody.
I'm new to efi, but sorta know the basic funtions of the different components involved.
I recently bought a 94 4wd burb that has had a nv4500 5sp swapped in. It also has an LS98 from a 91 camaro, Edelbrock tbi intake, Lunati 2nd level(I forget the specs) voodoo cam, and shorty headers into full 3" exh.
It has the original ecm for the auto trans, and altho it runs 'ok', its not right. It seems like fuel and timing are all over the place.
Could someone please point me to the correct place to start asking about the proper ecm for this rig and then eventually the tuning of it?

Thanks
