Old f9a system

[Boostaholic]

So I have recently acquired a never used f9a with complete wiring harness for a sbf. I am using it on a stack injection efi.
My question is, is it worth trying to use this old technology?
How hard will it be to get a tune for a pretty much stock sbf 302?
What are the first steps in tuning these computers?

Thanks for any help and if I'm not being clear, please ask and I'll do my best to answer any questions.
