so guys,first of all, I would like to figure out what to do with an eprom programmer

I can, for example, place the edc15 in the case of the block?

can I remap the ecu pi? old type motronic etc?

which programmer should I take?

I saw that there are x-progr,willem,wellon,top3000,upa, etc.

which would you recommend for me to spend not so much?
