I was wondering if anyone knew which of the following ecu's is the best for running my b16a engine? It's in a 91 honda civic HB
P28......Pr3......PW0....PO6.....P30.....or any others that are not listed.
All of these are compatable with my engine, but which one will maxamize my performance?

the ecu alone will not maximize anything. your choice of ecu depends whether you are obd1 or obd2.

Obd1
