can i use any ecu for the b20 or does it have to be the b20 ecu. what ecu would give me the most power

 

you need to use a ecu from a 96+ 5 speed integra ls, all b20 ecu's are automatic ecu's

 

If you want a few extra ponies, chip your ecu.

 

will any b-series ecu work

 

I just answered your question, if you get a b series vtec ecu it will throw a check engine light, if you buy a ecu for a automatic you will throw a check engine light, that leaves you with a B18B p75 ecu. If you can not understand that I dont know what else to say.

 

so if i get the vtec head i can use the vtec ecu then if im correct

read that before hand but short answer is yes

 

A converted p06, p28(chipped) or a p75.
