Okay, I bought a whole setup off of someone where I live. I have a 96 civic ex. the engine is a d16z6 out of a 95 civic ex. The engine came with the turbo, 550 RC injectors,p28 OBD1 ECU, vafc, and a vacuum box for the guage, bov, etc. I heard the engine running in the car it came out of so was confident with would be a simple swap. I got the new engine in and wired the vafc into the jumper harness to the p28 ecu. after everything was plugged in i started the engine. I was idling every rough and smoking horribly. I have the settings from his car to set the vafc to get it into a ballpark until i get it professionaly tuned but still no luck. I cannot figure out why the injectors are giving it way to much fuel, I dont know if im missing something with the vafc or what. I have been doing research and was wondering if the fuel injectors are getting too much volts to where they are staying open. If this is the case would a resistor box help. Im sure someone here has done the same swap. I bought all the jumper harnesses needed, One for the ECU and one for the dizzy. so its not a shitty wiring job. any imput is appriciated. Thanks

Throw that VAFC away and get the ecu chipped.
As for the injectors they should be saturated injectors for an OBD1 car, if not the could be peak and hold and would require a resistor box.

Also what color was the smoke?

they are saturated injectors. The ecu is chipped as well. something is just not adding up.

VAFC=very annoying ****ing contraption. Throw that away and dont bother.. you gain nothing from it. you could have wired something bad and caused a short
