i've looked on google and couldnt figure it out,
my car is a 92 civic hatch but when i bought it already had a b20b in it with a p-75 ecu and head, noww i bought a b16a head (pr3-3) from a guy. but im tryin to figure all this stuff out cuz a guy wants to buy my ecu and idk what to tell him (if its obd1 or not) so i desperately need the help on this
