I just got a 1993 Prelude with a H22a swap. I'm trying to figure out the V-AFC II, but I dont know what I'm doing. The guy that sold me the car said he rebuilt the engine... so I dont know everything that he installed (like piston type/ratio, cams, ect). I've been looking around on the V-AFC II and a few things dont work and/or do not display correctly. I'm wondering if he doesnt have some sensors configured or hooked up... or what is going on. Here is a few pics of what I see: Can somebody help me please? I dont know what year the motor is... so I dont know the terminal drawing to go by. I was going to check and see if everything is hooked up to the ECU right. How can I tell what year my motor is and what terminal drawing to use?
