A little history... I had decal pop (sas removed) so I replaced graphite ring. While I was in there I unplugged stator wires to clean and lube. Also unplugged rear o2 because it was twisting upon install. Got everything wrapped up. Went on a ride and fi light and lots of decel pop. Got home and read error code p0052 and a code for 2ndary tps short. Any help as to what to do next. Can I disable o2's? Or is that a band aid. I would like to keep them for fuel economy purposes. I am at a loss. Any guidance would be helpful.

I disabled o2's and the bike ran like crap. I ordered a used o2 for 50 bucks and hopefully that will fix it. I keep getting code 46 from the fi light the tuneecu tells me otherwise. Still don't know if I am chasing my tail. This doesn't seem to be a very active forum...

I guess my question is why am I getting different readings from two different sources? The dash fi and Tune Ecu don't agree. Upon inspection of the front o2 I noticed the po had taped a section and when I opened up the tape the two heater wires were exposed and I believe they had crossed causing failure. Again, would this simple shorting of a couple of wires cause multiple fault codes? Or simply cause the o2 to not function anymore?
I have MH plates, airbox, sas disabled and mivv carbons so I am not inquiring as to the validity of the function of these items but merely searching for some clarity because I was under the impression that you can never have enough info when it comes to troubleshooting. It just seems strange that the dash and TE don't agree when it comes to fault codes.

So i installed the new lambda sensor in the front but i am still getting a code 46 on the dash. So i hook it up to TE and it only shows a code for the rear cylinder. So i ran diagnostics on the lambdas and only got one code for the rear lambda. But the dash still blinks codes for the front cylinder. What gives? Will the dash reset itself eventually?

Right after i clear it and start her up the dash fi comes on. I replaced one o2 and ordered another. I may havs fried one by checking it with the multimeter. I'm certain the other one was fried from the two white wires touching. This sucks. All this because i needed to change the graphite ring. I wasn't aware that it could be done without removing the o2 sensors until after the fact. Hopefully two new used o2 sensors will clear the code because i am afraid i damaged one and the previous owner started the damage on the other one. I have mivvs and if i could find a map that would work without the o2 sensors then i would just shut them off. I tried that but it ran like ass.

I said Fuug it and threw an akr evo map in for the 08 SD and turned those o2's off and ripped on it. Map feels good so far and no fi light

You wouldn't happen to have that map would you ktmguy? If so so can you email it to me [email protected]
