Hey tephra Im still getting the good ol P0140. I was the MR that Bryan attempted to disable (about 3 weeks ago), but it was of no success. Any word on when this might be a fix? Would greatly appreciate it, as its getting kinda of old having to erase it every 40 or so miles. I have tried even a mechanical fix with no prevail.

so it didnt work for me..... whenever i try to log the afr from the rear sensor it keeps giving lower numbers than actual afr from my wideband. but at least i know its seeing some voltage. so i've tried a couple of different options with the dtc off, bit 1 off, still came on. dtc on, bit 1 off, still came on. dtc on bit on and now i'm getting a p0037 code. i'm gonna try dtc off bit on to see what happens.

I've been CEL free for a long *** time with what I mentioned before. Follow the tutorial on Wideband through the ECU, then disable P0139.
I've done this on multiple Xs, all with good result.
