Not trying to put down PW JDM, they got awesome products, but I just installed a obd2-obd1 conversion Harness for my LSV. I have a 99 SI head on a 94 B18B1 block. Well anyways I had a CEL code 9 (CYP #1 sensor). The problem was the #8 plug of the harness slipped out when I plugged it in. I finally figuered it out and held the wire in place and re-tried it. No CEL after that. just trying to help other people throwing the same code. Seen a lot if posts on code 9. Check the connectors and make sure they're all right. Sorry for the long post, just trying to help other people from my problem I had

 

thanks for the heads up... i dont think ill ever buy something from them. they have good stuff but ive noticed that theyre target market is more along the lines of upper class car modifiers. theyre stuff is expensive and they pride themselves on having parts readily available for the widely owned gtr and evoX...
