Or, check with KRC or another vendor doing flashes - I believe that rear O2 sensor can be programmed to be ignored. It's just there to check catalyst efficiency anyway....
you guys without cats need sims or you need a pcm flash to eliminate your cel.....
mechanical sims are different from electrical..... with mechanical, you install the mechanical sims in the back two o2 sensor positions, then install your o2 sensor into the sims...... see pic in link:
i used the #42002 part's from any local parts store for ~$6.00 a packet (you need a packet for each side)....... from each of the two packets, you need to drill out one of them with a 1/2" drill bit & install them like in the pics in the link above.... you'll probably have to unplug your battery to clear the code (~30 mins) & some driving time may also be involved to clear the code.....
what they do is remove your o2 sensors out of the exhaust stream enough to fool it into thinking there are cats...... work great on my system for over a year.........
you could also strap the back o2 sensors to the frame, but this wouldn't be my choice......
