Right now I have a B16B with a CTR PCT ECU. You think everything would work properly. However, the previous owner installed a VAFC for some reason and when I unplug it, the engine runs horribly. I am wondering what to do to get rid of the VAFC and get some proper tuning done. I'm thinking I may need an OBD1 conversion, but I don't know which direction to go. Hopefully I can get some help.

 

what year is your car what year is your harness and what year is your engine? also is your pct obd2a rectangle box or obd2b square box?

 

1992 Civic Si, it is the rectangle box

 

ok, so you have an obd2a pct in a 92 civic, is your motor still obd2? are you using the obd2 harness?

 

it is a ctr motor with a ctr ecu, so im assuming that everything is obd2a
