I recently bought a 97 turboed civic with a b18 and I'm fairly sure it has only been mildly tuned... The car runs ok but I'm planning on getting it tuned and just want to know if my ecu is working right with my car or.if I need a different one its a obd1 ecu any help is appreciated I'm learning as I go.. thanks

 

Gonna need a pic of the ecu, cover off if you can, and the code on the side of the case. Did you happen to ask what program the car was tuned on

Pic of the injectors, fuel pressure regulator would be helpful. Happen to know if it has an aftermarket fuel pump?
