i need to know how to figure out what type of ecu i have. i bought a integra with a b16 sirII swap and i want to use the ecu if it is a p28 for prelude till i get my new p13 back. i need to know if the one i have is a p28 or if it might be another series, the only thing i see is b16 written in magic marker on it and a sticker with a few numbers and letters on it but none saying p28 could someone please help me
